Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for photographing, reproducing and operating a scene including a subject, and recording an image, automatically trimming a part of the image, and editing the image. He is involved in the field of supporting video shooting technology.

[0002]

2. Description of the Related Art Due to the widespread use of small video cameras and video decks, ordinary people record and shoot images very often. In addition, digitalization of video equipment has been advanced, and attempts to realize video editing have been actively made in home computers. With the spread of digital media, it is expected that high-resolution, high-quality video images can be taken in the future, and that video data can be accessed at high speed.

[0003] However, there is a problem in that ordinary people photograph, but on the other hand, they rarely edit. This may have several factors. For example, editing equipment is expensive. Although photography equipment can be easily handled, editing equipment is difficult to handle. Nobody can see it even if you edit it hard.

[0004] Furthermore, it is considered that the difficulty in obtaining good materials suitable for editing is also one of the factors that prevent the editing operation.

[0005] The video that can be obtained by ordinary people as a material is a video taken by oneself. The images taken by ordinary people with their own video cameras can be broadly classified into two types. One is a case where a specific subject is focused on and tracked and photographed, and the other is a case where an entire scene unrelated to the specific subject is photographed. The former example is often seen when photographing friends and friends at some event. Representative examples are images of children at an athletic meet and images of friends at weddings, etc.
On the other hand, an example of the latter is to use a camera work to capture the beautiful scenery of the travel destination. Each example is shown in FIGS. In the case of the former example of “taking a picture around a specific subject”, when editing using the video, it is often used with the intention of taking the picture around that subject. is there. Of course, the meaning of the video is so ambiguous that it is not absolutely true.However, the editing work is very often performed with respect to the photographer's ideas and intentions. When shooting is performed at the center, the editing work is also performed around the specific subject.

[0006] However, despite the fact that it is possible to easily shoot a video due to the progress of shooting equipment, there are various difficulties and techniques that must be mastered in order to shoot a high quality video used for editing. . For example, there are various conditions such as stable camera work being desirable, a still image before and after panning, and appropriate shooting conditions such as framing, focal length, and aperture when shooting a subject. Several approaches have been proposed to address these issues.

For example, Japanese Unexamined Patent Publication No. Hei 7-115584, "Image Shake Correction Apparatus" aims to correct camera shake information which is likely to occur when a small video camera is handled, and absorbs fine vibration due to camera shake and stabilizes it. It can provide the video taken by the camera work. In this method, the range in which the scene is imaged is made larger than the range in which the scene is actually recorded,
It detects small movements and cuts out a part of the captured video so as to cancel the movements. This method is an effective method capable of photographing an appropriate material image by a relatively stable camera work from an image that becomes blurred due to camera shake when the image is taken.

There has also been proposed a video camera that summarizes the content of a shot video, divides it into sections so that it can be easily used as a material, and shoots in a state where the content is easy to grasp. For example, JP-A-10-28250, "Intelligent Video Camera and Intelligent Still Camera". This method arranges and classifies a video, which is one section obtained during ON / OFF of a camera for photographing, and displays a representative image, which is an image representative of each section, so that the contents can be grasped. ing. Immediately after shooting, you can check the content of the shot, so you can shoot again and again until you can shoot a video that can be used for editing, and the effect of increasing the possibility of acquiring higher quality material video Can be expected. Further, according to the present invention, a simple editing can be performed by combining the displayed representative images, and a function of adding character information to the representative image is also provided. Such added text information can be expected to have an effect of grasping what kind of video is included in the material video when editing work based on the shot video, and it is effective for obtaining video for editing. It appears to be.

However, as an imaging condition for obtaining the above-mentioned good material video, what angle of view should the object be photographed at?
The framing problem described above is generally left to the discretion of the photographer and involves difficulty. Such a sense of framing is usually acquired through experience, and furthermore, such framing generally does not have a correct answer, but rather is a very advanced video technique that must consider even the production intention. is there.
Unlike professionals who constantly shoot video, ordinary people who do not have many shooting opportunities have no way to determine what framing is good, and it is almost impossible to learn good framing.

[0010] Furthermore, in photographing an image, an opportunity to photograph a subject often comes only once instantaneously, and framing for photographing a subject must be determined in an instant. Determining framing and photographing an image in an instant is a very advanced technique and is considered to be a very difficult technique for ordinary people.

In the case where a specific subject is intentionally photographed, if the video includes the target subject and the camerawork is stable enough to be used for editing, a material to be used for editing is used. It can be said that the minimum conditions are satisfied as a video. That is, it is possible to provide an image that can be a material by combining the conventional techniques already introduced.

However, when aiming for further perfection, a method that can easily solve framing is desirable. Therefore, it is difficult to determine framing at the time of shooting, but it is possible to shoot a video in a wider area than the normally shot video beforehand, and to perform trimming as necessary from the video shot at the time of editing. If possible, it would be possible to obtain and edit video with better framing than to determine framing at the time of shooting. FIG. 11 shows an image of this realization.

FIG. 11 (a) captures an image in a capturing state. The view angle of the photographer at this time is similar to the view angle of the photographer (b). At this time, the image is photographed at the view angle of the photographer as shown in (b) due to camera shake or immature camera work. It has been assumed that The resulting video is
It is assumed that an image is surrounded by a broken line on the recorded image of (c). However, in practice, a video is recorded with a wider angle of view as shown in (c), and the image is captured by performing trimming as shown in (d) so that the framing becomes appropriate when used for editing. It will be possible to solve the problem of framing at the time.

On the other hand, at present, digital video editing machines are actively proposed and put into practical use, and devices operated by a simple personal computer for home use and application software are also proposed. A typical example is Ad
Obmi's Premiere and the like. These are provided with a simple trimming function so that a certain space in the video can be mechanically cut out.

[0015]

However, the trimming function proposed in the above-mentioned conventional digital video editing machine or the like is not suitable for an operation of changing a range to be cut out for each frame. Therefore, if the range to be trimmed is changed for each frame, the range to be trimmed must be specified for each frame. With this, it is not possible to achieve the optimal framing to build a better image by editing,
Future improvements are needed.

As described above, when an image is photographed while paying attention to a specific subject, it is meaningless if the subject is not included when framing. Therefore, even when the problem of framing due to trimming is solved, if the subject exists in the range to be trimmed, the trimming must be performed consciously.

A technique for recording an image over a wide area and automatically performing trimming so as to obtain a high-quality framing image, and if an object exists, it is possible to perform trimming including the object. Required.

As described above, the framing of an image including a subject that is difficult to determine instantaneously when shooting is performed.
In order to make it easier to perform, by trimming the video at the time of editing as needed from a video that has been shot widely in advance, it is possible to obtain an optimally framed video with a small number of operations. In order to achieve this, it is necessary to implement a technique for appropriately and automatically trimming a spatial range including a subject.

An object of the present invention is to appropriately and automatically trim a spatial range including a subject from an image that has been taken in advance in a wide manner, so that it is difficult to instantaneously determine the subject at the time of shooting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific embodiment of an editing video photographing method and apparatus with a subject trimming function will be described below.

First, FIG. 1 shows a flow chart of an embodiment of an editing video photographing method with a subject trimming function according to the present invention.

First, there is a scene 0 to be photographed.
Here, it is assumed that there is a subject that the photographer 20 particularly wants to photograph. By shooting step 11, this scene is
The image is captured as the image 1 including the object. The video 1 containing the subject is recorded as a video recording 2 in a video recording step 12. The means for recording the video used here is not particularly limited. However, it is needless to say that the recorded video must be capable of reading out the recorded video and reproducing it as a video in the video reproduction step 13. For video recording, camera ON / OFF,
Various information such as lens parameters and time information are also recorded.

The editor 21 designates the designated range 4 in the space range designation step 14 for the video information 3 read from the video recording in the video reproduction step 13. This serves as a reference frame for performing trimming from the recorded video. Next, the editor 21 designates the in-range subject 5 in the in-range subject designation step 15 in order to designate a notable subject existing in the designated range. In this way, based on the designated range 4 and the subject 5 within the range designated by the editor 21, in the range change corresponding step 16, the cut-out video information 6 in which the range to be cut is calculated is output from the video information 3. When the range to be cut out on the video is determined, trimming video information 7 is output from the video recording in the video cutout step 17 based on the determined range. The trimming video information 7 has already been considered for trimming for editing, and it has been subjected to framing considered by the editor. Using the video information as a material, the editor 21 performs an editing operation or an operation necessary for editing in a video operation step 18 and outputs the operated video 8.

FIG. 2 is a block diagram showing an embodiment of an editing video photographing apparatus having a subject information acquiring function according to the present invention.

The photographer 20 captures an image 31 of a subject through the photographing means 60 with respect to the scene 30 of the subject.
This photographing means converts optical information into electronic information using a CCD or the like, and converts the information so that it can be handled by an electric circuit. There is no particular limitation on the number of pixels, the angle of view at the time of shooting, and the focal length. However, it is assumed that the photographer shoots at a size larger than the angle of view and size that the photographer intends to shoot. As for the size, the larger the size, the better.

The image 31 containing the subject thus photographed is stored in the recording medium 40. Although no particular designation is made for the recording medium, it is preferable that the recording medium be sufficiently recorded and easy to retrieve. For example, it is a magnetic disk, a medium using optical information, or a tape medium. The recording format, size, shape, and recording medium of the video information to be recorded are not particularly limited, but may be any format that can reproduce the video recording to be stored.

The angle of view and the size of the image that the photographer intends to shoot, the angle of view and the size of the image recorded in the actual image, and the angle of view of the clipped image used in editing that will be described later. And its size is not specified, but the angle of view of the recorded video and its size are
The larger the angle of view and the size of the image to be shot, the better. The angle of view and the size of the video used at the time of editing do not matter if it is smaller than the recorded video because the conversion is performed. However, it is preferable that the angle of view and the size of the video to be shot are substantially equal to each other. .

Video recording 3 recorded on recording medium 40
2 can be read from the recording medium 40 as the video information 33 by the video reproducing means 61 and reproduced. For this video information 33, the editor 21 specifies a specified range 34 which is a range to be trimmed from the video information by the space range specifying means 62. If not specified, a predetermined trimming range is used. This is because the angle of view intended by the photographer is stored together with the video recording, and a reproduction of the angle of view may be used, trimming may be unnecessary using the entire video recording, and editing may be performed. An area in the center of the screen may be used according to the size.

This specified range is basically used as a video for editing, and its ratio is desirably based on the ratio of the video to be edited. However, the scale may be changed in some cases, and if the ratio does not match,
A single color area such as black may be added. FIG. 5 shows an example of the specified range and the result of the trimmed video according to the specified range. When there is no designation, it is determined here that the same thing as the viewing angle of the photographer is used (FIG. 5A).

If the size of the specified range is equal to the size of the video for editing and only the trimming position is different, the position is shifted by the amount of movement (FIG. 5B). Video for editing,
If the frame of the range with the image to be trimmed has the same ratio, but the size is different, the resolution is changed, and in some cases, the image is complemented or degenerated (FIG. 5D). If the ratios of the ranges are different, fill in a black area so that the ratios match (FIG. 5C).

When there is a subject to be noted in the specified range, the editor designates the subject to be noted. This step is performed via the in-range subject specifying means 63 to determine the in-range specified subject 35. The present invention is primarily intended to compensate for the problem of framing at the time of shooting by trimming at the time of editing.
It cannot be specified. If the editor does not particularly specify the subject, the trimming is performed as it is.

Basically, for the work in the space range designating means and the in-range subject designating means, the editor may designate each frame at a certain time interval.

For example, it may be mechanically time-wise, frame-wise, or shot-by-shot. In the case of each shot, the start of the shot may be used, or the end or the center may be used. In the present embodiment, the range is specified for each shot, and the range is specified in the first frame of the shot. Of course, you can change the range during the shot. Similarly, when specifying the subject within the range,
Basically, the designation is made in the first frame for each shot as in the spatial range designation means. However, since the subject does not always appear in the shot, the designation may be made in the middle of the shot. The specified range and the time range affected by the specified subject within the range may be a few frames before or after the specified frame, or all of the shots to which the specified frame belongs, or the next specified range. It may be until it is done. In the present embodiment, since it is assumed that designation is performed for each shot, if a space range and a subject are designated in any frame including the beginning of the shot, the designation is performed in all of the same shots. Shall be affected. If different designations are made within the same shot, priority may be given to the ones that are close in time to the multiple designated ranges, or to explicitly specify the part over which the setting range extends You may. This is shown in FIG.

In FIG. 7A, the content specified in the first frame is reflected on all frames in the same shot. Next, when a designation is given to another frame, the designation reflected on each frame is a frame existing at a distance close to the designated frame (FIG. 7).
(B)). For a frame specified later, the range affected by the frame may be explicitly specified.

When a subject within the range is set, it is often assumed that the editor wants to compose an image around the designated subject, and estimates the image around the subject. The target subject is not always stationary in the same shot. This may be due to camera work, movement of the subject itself, or the like. The movement of the subject is tracked, and the position of the subject is always estimated. There are various methods for tracking the subject. Here, an example is shown in which a process based on block matching is performed, a difference is calculated for a similar region around the designated region, and a region is moved when there is a region with the smallest difference. . This is shown in FIG.

FIG. 8 schematically explains block matching. Region p in an image f (t)
In (k, t), in order to search for a frame to be searched, p (k, t + 1) of (generally the next frame) f (t + 1), an area corresponding to p (k, t) is variously changed. Move, calculate the difference for each corresponding pixel in the area, and set the area where the difference is the smallest as the subject area.As information used when performing the difference calculation, information such as brightness, color, etc. Used. In the present embodiment, the RGB lightness difference sum is used as information for difference calculation.

Next, based on the set space range and the tracked subject, the space range to be trimmed is actually determined by the range change correspondence means 65. If the subject is relatively stationary, trimming may be performed mechanically.If the specified subject is tracked and it is determined that the subject is moving, the spatial range must be changed. May have to happen. There is no particular problem if the subject exists within the designated space range. However, if the subject exists outside the space range, the space range is changed. This change is based on a preset rule. For example, the range may be moved in the moving direction of the subject, or if the size of the subject is changed by zooming in / out, the setting of the spatial range may be changed accordingly. However, it goes without saying that such a change in the range does not extend beyond the frame of the recorded video. FIG. 6 shows a state of trimming reflecting this tracking result.

FIG. 6 shows a case where the subject itself moves and comes out of the initially set space range. As shown in FIG. 6B, the subject jumps out of the spatial range. In response to this, the position of the spatial range is moved and the trimming area is changed so that the subject can be accommodated (FIG. 6 (3)). In response to this, the final trimmed video has a format as shown in FIG.

When the spatial range becomes clear and the range to be actually cut out becomes clear, the video cut-out means 66 cuts out the video. This outputs a trimmed image 38 for a designated space range. The editor operates the video with the video operating means 67 for the trimmed video 38 as needed. The contents of this operation are premised on editing work, and play, trick play, delete, add video, rearrange, arrange for seams,
Includes all operations intended to change the contents. Note that this step is an operation itself, and it is needless to say that there is no need to set restrictions according to the purpose.

FIGS. 3 and 4 show an overview and an operation image of an embodiment of the apparatus of the present invention.

The photographer uses the photographing and recording device shown in FIG. A scene 100 existing ahead of a photographing optical axis 102 is photographed through a photographing lens 101 and recorded. The angle of view of the photographer,
The image according to the parameters set by the photographer is displayed as an image 104 on the liquid crystal monitor 103. This corresponds to the range 110 shot in the actual scene.
On the other hand, the video is actually wider and larger than the viewing angle set by the photographer, without being conscious of the photographer. For example, 1
The angle of view of the image is as shown in FIG. Therefore, in actuality, the image scene input through the photographing lens 101 is photographed at a wider angle of view than intended by the photographer. The photographer can control the start and stop of recording of the camera by using the photographing control button 106, and can operate various parameters that influence the photographing conditions by using the various control buttons 105.

When a video is shot with the above-described device,
Next, in order to perform trimming on the video, a spatial range and a specific subject within the range are estimated as necessary. This is shown in FIG.

The editor controls the recorded video with the playback control button 125 and confirms the content. For the confirmation, all the images may be confirmed, or a part such as the beginning, end, and center of the shot may be used. It is needless to say that the recorded video has a larger viewing angle than the video captured by the photographer at the time of capturing, that is, a large image. At the time of reproduction, the range at the time of photographing is specified so that the viewpoint of the photographer can be recognized.

Next, a spatial range and, if necessary, a subject are specified for a required video recording location. In FIG. 4, the input operation pen 121 is used for the operation on the series of images. However, a separate mouse may be used, or the control command 124 on the screen may be operated with a finger or the like using the liquid crystal monitor 120 as a touch panel. Alternatively, a wired or wireless operation interface may be used, a control button used at the time of shooting may be used, a keyboard-type input may be used, or a general input interface for digital equipment may be used. Through this operation, the range to be trimmed is determined from the designation by the editor and the calculation result including the tracking of the subject. When the trimming range is determined, trimming is performed from the video recording, a final video is obtained, and operations related to editing work are performed.

The embodiments of the present invention have been described above. In the present embodiment, all operations can be performed by a single housing, but the operations may be performed by a plurality of housings. In addition, the above method is described in a computer program, and ROM, FD, CD, DVD, memory card,
It is stored in a storage medium such as a removable disk,
By using a computer having a function of acquiring a video, having a recording medium for recording various kinds of information centering on a video and a subject, and having a calculation function of reading and executing the computer program, the same processing can be constructed. Is quite possible. Note that the above-described embodiments are some embodiments for reproducing the essence of the functions, and even if some functions and specifications that can be easily analogized are changed, they are also within the scope of the present invention.

[0071]

According to the present invention, when an editor intends to edit a video centering on a specific subject based on a video shot by the user taking a particular subject into consideration, the photographer specifies Since it is possible to organize and construct a video using information of a subject, it effectively functions for simple video editing.
