Apparatus and Method for editing 3D image}

The present invention relates to an editing apparatus and method for generating a stereoscopic image, and in particular, to perform a preprocessing process of image synchronization and multiplexing of an image obtained from a camera without additional hardware means, and to provide a self-editing function to obtain a clear image. It relates to an apparatus and a method for providing.

Recently, the display technology is combined with the human body research technology to effectively stimulate the user's vision to provide a more realistic and stimulating image technology. Therefore, a method for producing stereoscopic images is actively researched by adding depth elements using parallax to images previously provided in 2D by analyzing a process in which light is transmitted to both eyes of the user and stereoscopically judging an object. have.

The general principle for providing a stereoscopic image using the parallax as described above is to take an image with two cameras arranged to correspond to the positions of the left and right eyes of the user, so that the captured image is reflected on the corresponding eyes, respectively. . At this time, the method of mapping the image of each camera to the corresponding eye is to change the polarization, color (mainly red and blue), brightness of the left and right eyes, or open and close the images alternately in time. . As a result, the darker the perception of the three-dimensional effect due to the difference in color or brightness, the longer the duration of the latent image generated in our eyes is caused by the disparity in the image recognized by the left and right eyes.

The stereoscopic feeling in the stereoscopic image obtained by the image processing as described above appears due to the difference between the left and right images of the object projected to the two eyes, and is recognized as the three-dimensional stereoscopic image through the brain synthesis process.

In the production of live stereoscopic contents for providing the stereoscopic image to a display, a preprocessing operation for receiving two left and right image signals from a stereoscopic camera and synchronizing them and converting them into a stereoscopic image format and editing to convert the stereoscopic contents into a stereoscopic image format It is created through work. The stereoscopic image may also be referred to as a stereo image.

The preprocessing process of the three-dimensional content production is mostly performed using a hardware synchronous control controller called a frame synchronizer and a hardware multiplexer. The frame synchronizer accurately synchronizes images captured by dividing the left and right sides. This is to prevent awkwardness that occurs when stereoscopic images are formed by using misaligned frames. The hardware multiplexer is for real-time conversion into a stereoscopic image format suitable for the type of stereoscopic display to display the synchronized left image and the right image or to store the result.

FIG. 1 is a diagram illustrating a photographing unit for basic left and right image capturing, as shown in FIG. 1, a frame synchronizer 20 for synchronizing a left camera 10a and a right camera 10b and images thereof, and the frame synchronizer 20. It consists of a multiplexer unit (hereinafter, simply referred to as a 'muxing unit'), that is, a muxing unit 30, which generates the synchronized left and right images provided by the 20 as an appropriate stereoscopic image. Sometimes, the frame synchronization unit may not be necessary in case of cameras equipped with a means for synchronizing frames (gen-lock) or a camera made exclusively for capturing stereoscopic images during simultaneous shooting. Based on the frame synchronization unit 20 is essential. The muxing unit 30 converts the captured image into a stereoscopic image format in real time and checks the stereoscopic image display means. The frame synchronization unit 20 and the muxing unit 30 use a hardware device. have.

FIG. 2 illustrates an image obtained by photographing the object 40 of FIG. 1 through the photographing unit as shown in FIG. 1. FIG. 2A illustrates an image obtained through the left camera 10a and an image obtained through the right camera 10b. 2b shows output images when the muxing unit 30 converts them to a stereoscopic image in the form of side by side.

Commonly used stereoscopic images include the above side by side format, top by bottom, interlace, round, frame sequential formats, and the like. It is determined according to the type of the stereoscopic image display means for implementing.

3 shows an example of an editing screen 50 of software for editing left and right images obtained through the photographing unit as shown in FIG. 1 into a stereoscopic image, and since there is no dedicated software for producing a stereoscopic image, a general moving image is shown. The editing software is used to perform the manual work frame by frame. The illustrated edit screen 50 shows an example using a representative video editing software "After Effect", which is applied to each of the left image 52 and the right image 53 to generate a stereoscopic image in a horizontal interlaced format. A mask 51 is set, and a degree of positional movement of each image is specified for each of the left and right images for depth control, and each of them is masked and synthesized to create a horizontal interlaced stereoscopic image 54. You can confirm the setting.

The stereoscopic image obtained through the above-described process is focused on simply providing a stereoscopic image, and is focused on applying the same image quality correction between the left and right images, so that a user may easily feel tired when watching the stereoscopic image for a long time. I overlook that it can. In other words, in reality, both eyes of a person receive a three-dimensional object, there is a difference in the degree to which the light reflected on the object is focused in both eyes, while there is a relatively less sharp part, the conventional three-dimensional image production method is Ignoring the same principle and focusing on matching the left and right images or adjusting the depth, the sharpness is set higher than that of observing a real object even in the case of the lack of sharpness as described above, thereby increasing the feeling of fatigue on both eyes of the user. There was a problem that you can not watch stereoscopic images.

In addition, since all the processes for producing a stereoscopic image as described above must be performed manually, if the production takes a long time, and the operation to adjust the depth for a certain section is required to repeat the manual operation. For example, a stereoscopic image for displaying on a large screen and a stereoscopic image for displaying on a small screen, even if the stereoscopic image of the same content has to be different in depth of stereoscopic images, even if the same left and right video sources are used, The contents to be provided to the user must be edited and produced differently. Therefore, manufacturing time and cost by this manual operation will inevitably increase. In particular, since an expensive and bulky frame synchronizer or multiplexer is required, it is difficult to popularize stereoscopic contents, resulting in a delay in the spread of stereoscopic displays.

The purpose of the present invention is to newly produce a three-dimensional image that requires expensive hardware equipment or complicated editing operation as described above, at a low cost and simply. By synchronizing images, an apparatus and method for stereoscopic image editing are provided so that left and right images can be synchronized using only a software module without a separate hardware synchronizer.

Another object of the embodiment of the present invention is to provide a plurality of verification process in the frame synchronization process to minimize the error occurring in the synchronization process to prevent errors in the three-dimensional image production process according to the time difference of the frame, synchronization process through the general hardware The present invention provides an apparatus and method for editing a stereoscopic image that can compensate for a gap between the video data.

Another object of the embodiment of the present invention is to provide a simple editing through the user interface by providing a dedicated editing means for receiving the synchronized left and right images and display them together in units of frames, and adjust the depth of the three-dimensional depth in units of frames and pixels. The present invention provides an apparatus and method for stereoscopic image editing that can generate a moving image in a desired stereoscopic image format only by manipulation.

Another object of the embodiment of the present invention is to accept the synchronized left and right image to give a color difference to the object displayed in the frame, to compensate for the difference between the user observes the actual object, the user can watch the stereoscopic image for a long time The present invention provides an apparatus and method for stereoscopic image editing.

In order to achieve the above object, an apparatus for editing a stereoscopic image according to the present invention includes an image processor for digitally processing left and right images and audio signals obtained from a camera, and processing the same quality of the left and right images, and providing the same. A stereoscopic image preprocessing unit for acquiring left and right images and audio signals from a processor, comparing a maximum value of a set signal based on the audio signal, synchronizing a corresponding portion, and converting the same to a preset stereoscopic image format; And a stereoscopic image editing unit configured to display an additionally provided stereoscopic image format on a frame basis and to synthesize the stereoscopic image format.

In this case, the stereoscopic image preprocessing unit and the stereoscopic image editing unit may be computer software capable of acquiring the left and right image and audio signals.

The maximum value of the signal may be a maximum value of RMS signals corresponding to left and right images generated by processing by a root-mean-square (RMS) method based on the audio signal.

In addition, the stereoscopic image preprocessing unit synchronizes by delaying or extending any one of the signals corresponding to the left and right images based on a time difference between a specific adjacent portion where the maximum value of the signal coincides between the left and right images. The stereoscopic image preprocessing unit may synchronize when a time difference of a specific adjacent portion where the maximum value of the signal coincides with a preset time range.

In addition, the 3D image preprocessing unit compares the synchronized signals by time within a preset time range and outputs whether the synchronization is completed when the maximum time-matched value is equal to or greater than a preset number of times, or performs integration within a preset time range. The apparatus may further include a verification unit configured to output whether the synchronization is completed by comparing the generated integral values. In this case, when the synchronization is not completed, the verification unit may initialize the synchronization process and return to the audio signal of the first left and right images.

In addition, the stereoscopic image editing unit compensates for left and right parallaxes by selecting a predetermined range of pixel sets constituting a specific frame to adjust color difference, and the same pixel as the pixel set for a frame adjacent to the color difference controlled frame. The range may be determined and color difference adjustment may be performed on the pixel range under the same conditions as the color difference adjustment. In this case, the color difference adjustment may be an adjustment for any one of saturation, brightness, and sharpness.

In addition, another embodiment of the present invention for achieving the above object is the step of photographing the left and right image information and audio information at the same time, and receiving the left and right image and audio information to detect the audio signal for each image And synchronizing an image by comparing a maximum value of a signal set based on the audio signal and synchronizing a corresponding portion, and converting the synchronized left and right images into a stereoscopic image format. do.

At this time, the maximum value of the signal in the step of performing synchronization may be characterized in that the maximum value of the RMS signal generated by converting the audio signal to the RMS method.

The method may further include verifying by synchronizing the synchronized signal and outputting whether or not the synchronization is completed in the performing of the synchronization, wherein the verifying is performed within a preset time range based on the synchronized signal. If the maximum time value for each time is more than a predetermined number of times, whether or not the synchronization is completed, or based on the synchronized signal by performing the integration within a predetermined time range by comparing the integral value generated and outputs whether the synchronization is completed or not; can do.

As described above, the apparatus and method for editing a stereoscopic image according to an exemplary embodiment of the present invention may perform synchronization of left and right images based on audio information obtained after capturing left and right images, thereby providing a separate hardware synchronizer. Without the software module alone, the left and right images can be synchronized, reducing costs and increasing user accessibility.

Apparatus and method for stereoscopic image editing according to an embodiment of the present invention has an effect of providing a clear stereoscopic image by increasing the accuracy of synchronization of left and right images through various verification of the synchronized audio information.

An apparatus and method for stereoscopic image editing according to an embodiment of the present invention includes a dedicated editing means for receiving the synchronized left and right images and displaying them together in units of frames while controlling the depth of stereoscopic depth in units of frames, sections, and pixels. By providing a video, an image of a desired stereoscopic video format can be simply generated through an easy user interface.

Apparatus and method for stereoscopic image editing according to an embodiment of the present invention provide a stereoscopic image corrected to the same level as observed in a real object, thereby compensating parallax and allowing a user to watch a stereoscopic image for a long time.

Embodiments of the present invention as described above will be described in detail with reference to the accompanying drawings.

4 is a conceptual diagram showing an operation of an embodiment of the present invention, through which the overall operation of the present invention will be described. The conceptual flow chart shown in the upper part (a) of FIG. 4 and the exemplary information shown in the lower part (b) are arranged in each order.

Looking at the schematic flow of the present invention through the conceptual flowchart of the upper part for obtaining the content of the real-life stereoscopic image shown in the drawing, first, the left and right moving images (collectively referred to as the image and audio signal) are obtained by using a photographing means, and directly (directly) Connection) or indirectly (data transfer only) to an application program running on a computer (S1).

In this case, the provided left and right videos may be processed by digital signals and transmitted, and in order to solve the difficulty of controlling an image due to the quality mismatch of the left and right videos, the application program may match the picture quality of the video according to a preset correction setting. have. In other words, by analyzing the image quality information of one of the left and right videos, it is possible to set the image quality information as a reference of the correction setting, and to correct the other one corresponding to the image quality information (S2).

In this case, the image quality information or the correction setting may be a setting regarding saturation, luminance, sharpness, etc. of an image.

After the above process, images of the same object having different viewpoints are presented as shown in the lower portion of the left and right moving images. The application program executes each of the following functional blocks S3 to S7, which may be a single software or a program module (DLL, OCX, ActiveX, etc.) and integrated software for managing the same. It encompasses virtually any form that can be implemented in software rather than hardware. In the present embodiment, an application program running on a personal computer is merely an example. However, the application program may operate on a dedicated device, a remote server, or a virtual computing environment. This is irrelevant to any environment in which the application program can be executed. However, it is advantageous in terms of general versatility to be a general program that runs under a general operating system in a general-purpose widely used personal computer.

Looking at the operation of the functional blocks (S3 ~ S7) that operate in software, first to extract the audio signal of the left and right video provided (S3). The audio signals are filtered to remove noise (S4). An exemplary waveform at this time is shown in the lower portion, and as shown, it can be seen that the left and right audio signals are shifted. This is caused by the fact that the actual shooting timing is different when using a photographing means without a special device (eg, Gen-Lock). When this is converted into a stereoscopic image format, the quality of the stereoscopic image is deteriorated.

Accordingly, the RMS signal is generated from the noise-free left and right audio signals extracted through the steps S3 and S4 by using a root-mean-square (RMS) scheme (S5), and for the left and right audio signals over time. The synchronization process may be performed by comparing the maximum value of the RMS signal with reference and adjusting the time difference to match the maximum value (S6). In this case, the maximum value may be synchronized with the same signal when the difference with the other RMS signal is within a preset error range based on the maximum value of the RMS signal of the left and right audio signals. .

That is, it can be easily synchronized using only a portion of the RMS signal within a predetermined time range, and more specifically, to set a specific section or one of the RMS signals for the left and right audio signals within a predetermined time range. The time difference is measured by comparing parts of the maximum value of the other one RMS signal with respect to the maximum value based on the maximum value, and delaying or extending the time of any one of the RMS signals. Synchronization can be achieved by compensating for and matching the differences.

In this case, the time difference between the RMS signals is preferably made within a predetermined threshold. The reason is that if the maximum value of the RMS signal coincides but there is a significant difference in time interval, there is a high possibility that the frames of the left and right images corresponding to the portion where the maximum value coincides are not the same, so that the time difference between the frames is constant. This is to prevent a case where the maximum value of the RMS signal coincides but the frames are not identical by providing a reference.

Therefore, when the time difference is out of the predetermined threshold value, it may be regarded as different frames to prevent the occurrence of an error and precise synchronization may be performed. Therefore, if the time difference between the RMS signals is within the threshold, synchronization is performed by matching the maximum value between the RMS signals.

In addition, after synchronizing using the maximum value of the RMS signal as described above, the step of verifying whether the synchronization is performed correctly may be performed, which may be followed.

Firstly, a predetermined time range or a user-specified time range is reset for the synchronized RMS signals using the maximum value of the RMS signal, so that the maximum value of the RMS signals within the time range matches. In case of more than the set number of times, it may be determined that the synchronization is normally performed and may output whether the synchronization is completed. Second, it is determined whether the synchronization is completed by determining that the synchronization is normally performed when the integration value is matched by resetting the preset time range or a user-specified time range with respect to the synchronized RMS signals. You can also output it. In particular, it is a matter of course that the error range can be allowed when comparing the integral values.

If it is less than a predetermined number of times through the verification as described above, or if the integral value does not match, the synchronization may be outputted and initialized with an audio signal before the synchronization process to perform the synchronization again.

Although described based on the RMS signal as described above, this is merely described as an embodiment of the present invention, and can also be synchronized by setting and comparing reference values based on the audio signal in other ways.

The synchronization process is configured to process a hardware device such as a frame synchronizer in a software manner, and thus it is possible to synchronize left and right videos through a low cost and a simple method.

In addition, the left and right videos synchronized through the above process are applied to a dedicated editing program to be described later or directly provided to another type of program or a 3D video display. Since the stereoscopic image formats are mixed according to the stereoscopic display method, it is preferable to support various formats so that one of them can be selected and stored. However, if the purpose is to be applied to a dedicated editing program to be described later, the sequential frame method (the method shown below), the side-by-side, or the top-by-bottom method, which is the simplest stereoscopic video format, may be used.

The process of generating the synchronized left and right images in the stereoscopic image format is also a software method, which can effectively replace an expensive hardware multiplexer. That is, the existing hardware multiplexer is an essential equipment used to monitor the content and state of the stereoscopic image to be taken by applying the result to the stereoscopic display when the image is taken. However, the hardware multiplexer is considered to be one of the main reasons that stereoscopic image content production has not been universalized because it is very expensive and bulky. However, the illustrated process of performing muxing in software (S7) can generate synchronized left and right moving images in a single stereoscopic image format without expensive hardware equipment.

In addition, when the stereoscopic image format is applied to a dedicated editing program to be described later, the stereoscopic depth control provided by the editing program is free, and if desired, the result of adjusting the stereoscopic depth may be checked through the stereoscopic display. The muxing process S7 may be omitted, and the dedicated dedicated editing program may directly use the synchronized left and right moving picture information.

5 is a diagram of a dedicated stereoscopic editing program that reads a stereoscopic image format obtained through the above process, sets a desired frame section to a desired level of depth, and then converts the stereoscopic image format into a resolution and stereoscopic image format suitable for a target stereoscopic image display. The screen configuration example is shown.

The screen 100 provided as illustrated includes a left image display area 101 displaying a left image and a right image display region 102 displaying a right image, and adjusting a stereoscopic depth of the left and right images. There is provided a left and right image adjustment window 110 including a color difference correction window for compensating a difference in image quality of the left and right images through a depth adjustment window and color difference correction.

In addition, the frame editing window 130 provides a plurality of frames in a row so that it is easy to select a desired frame among a plurality of frames and to easily set a desired frame section, and the left and right audio signals corresponding to the provided plurality of frames. Indicative audio editing window 140 is provided.

In this case, the audio editing window 140 may be synchronized by manually adjusting and matching the time difference between the left and right images by respectively providing signal level control scroll bars for synchronizing the left and right image audio signals in response to the left and right audio signals. . In addition, based on the time at which one signal value of the audio signal level of the left and right images is positioned through an input window provided by clicking an input button provided on the right side, By inputting a value for the difference to delay or extend the signal, synchronization may be performed by matching the time at which the reference signal value is located. In addition, the frames corresponding to the left and right video audio signals may be displayed in the frame editing window 130 according to the control of the left and right video audio signals.

In addition, it is obvious that the process of matching signal values of the left and right images may be automatically performed through a predetermined algorithm in addition to the manual adjustment as described above.

After performing the above synchronization process, click the verify button located at the right end of the audio editing window 140 to check whether the matching signal value meets a predetermined threshold or integral value as described above with respect to the synchronization result. By judging, verification can be performed to output the completion of synchronization, and this can be informed through a separate display window.

In this case, if it is determined that the synchronization has failed, it may be initialized to a previous step of the conversion process for the left and right video audio signals and may be performed again. Preferably, the step before the conversion process is a step before generating the RMS signal.

In addition, a frame progress scroll bar 150 for setting an edit position to move quickly to a desired edit point on a frame basis, a status output window 160 for displaying a current state, and a menu bar 120 for displaying various menus are provided. Consists of. In this case, the frame progress scroll bar 150 may be provided with an input button on the right side to move to a desired frame point like the input button function of the audio editing window 140.

Each information displayed on the single screen does not necessarily need to be displayed on a single screen. Some of them may be displayed only when a specific menu is selected, and the configuration of the screen may be variously changed.

Although not shown, an additional stereoscopic image display area for displaying stereoscopic contents at the same time as frame editing through stereoscopic image display is added, or a menu for providing a stereoscopic image of the current frame in full screen is provided. It may be configured to quickly check the three-dimensional state of the current frame (or frame section).

The user interface composed of the elements constituting the screen 100 may naturally be controlled by various input means, which may include a general keyboard, a mouse, a tablet, a touch pad, a voice, and the like. It is self explanatory and is not shown separately.

Looking at the functions provided by the interface through the user interface provided on the screen 100, first, the stereoscopic image editing program provided with the screen 100 is generated by the method described with reference to FIG. 4 or other various methods. The stereoscopic image format may be called to separate left and right images and provided to the user in units of frames. In addition, the depth of the three-dimensional effect can be adjusted (in real time, if necessary) in units of frames, and the three-dimensional effect can be collectively adjusted through the section setting. In addition, after completing this process, and converts the left and right images and audio signals to the desired resolution and stereoscopic image format again.

In other words, when the user executes the editing program and selects a desired 3D image format, visual information on the left and right videos is provided in units of frames, and the user can select a 3D effect as a whole, and a desired part is 3D in units of sections or frames. It can be adjusted differently, and by converting it to the desired resolution and stereoscopic image format, it is possible to easily generate content suitable for the desired stereoscopic image display.

In addition, the left and right image adjustment window 110 includes a pixel section setting function for setting specific pixel sections 101a and 102a of the frame using the editing program, and color difference correction for correcting color differences for the pixel sections. The color difference correction window may be used to correct saturation, luminance, sharpness, etc. of the pixel section.

In this case, the setting information generated by designating the first pixel section 101a in any one of the left and right images and adjusting the color difference is used in the first pixel in the other one frame corresponding to the specific frame. The second pixel section 102a corresponding to the section 101a may be automatically designated, and the same content as the setting information may be automatically applied to the second pixel section 102a.

In addition, the editing program stores the setting information of the pixel section set in the same manner as described above, and sets at least one adjacent frame section before and after the frame based on a frame including the set pixel section to move the pixel section. By tracing, the setting content may be applied to the pixel section included in an adjacent frame.

By doing this, in order to prevent the user from seeing the blurry part of the object in the stereoscopic image providing process to increase the fatigue of the user's eyes, by setting the pixel section corresponding to the blurry part It is also possible to compensate for left and right parallax by performing color difference correction.

The editing program may be integrated with the synchronization and muxing program described with reference to FIG. 4, may be divided into different programs, and may be divided and configured into a module state, and then may be selectively called and managed by an integrated management program.

When the left and right video sources including specific audio synchronization information are prepared as described above, the following processes of 'synchronization', 'muxing', 'stereoscopic editing', 'video editing', 'resolution conversion' and 'stereoscopic video format conversion' are all performed. Since it can be implemented through software, it is very easy to generate real-time stereoscopic image contents, and the hardware burden and cost for this can be greatly reduced.

Then, the software processes described together with the various possibilities are collectively described through an example of the overall operation sequence illustrated in FIG. 6.

First, after determining a target stereoscopic image display, a source video is input to generate a stereoscopic image format having an appropriate resolution. It can be input in real time directly through a hardware connection, in the form of a file, or in some cases by streaming over the network. In this case, when the source video is received through a hardware connection, the source video is digitally processed.

The left and right videos are extracted from the source video and the left and right videos are corrected by using predetermined color difference information or by compensating for the quality of the remaining videos based on the quality of any one of the left and right videos to compensate for the difference in picture quality between the left and right videos. Unify the quality difference between the two.

Subsequently, frame synchronization is performed on the left and right audio signals included in the source video based on the maximum value of the RMS signal generated by the RMS method. Then, the verification function determines whether the synchronization is properly performed and outputs whether the synchronization is completed. Executes or initializes the editing function.

After the verification process as described above, a process for generating a stereoscopic image format using a muxing function or an editor for editing the synchronized left and right videos without the muxing process is executed.

After executing the editor, a section for editing is set to adjust a three-dimensional effect or frame-by-frame editing, wherein the editing section is set to a partial section or a whole section or a single frame designated by a user, and the three-dimensional adjustment is left and right parallax. Are adjusted individually or simultaneously. At this time, the three-dimensional adjustment may be performed by a two-dimensional curve conversion method, the resolution adjustment for the hole compensation may be performed. Frame-by-frame editing allows you to insert or delete specific frames and apply specific effects, similar to general video editing.
