Description

  The present invention relates to an image display device for comparing a plurality of images acquired by re-shooting or continuous shooting.

  In recent years, the capacity of a recording medium using a flash memory has been increased, and a digital camera using such a recording medium has come to shoot without worrying about the number of shots. In such a situation, there are many cases where continuous shooting or re-taking is performed with different settings, and as a result, a large number of photographs having the same composition are obtained, and it takes time and effort to select images for storage and printing. It has become like this.

  When the user compares and selects images, the point of interest varies depending on where the comparison target image is captured and where the image difference is. For this reason, for example, the following operations may be performed in the image display for comparison on a personal computer (PC).

(1) When re-taking with a different exposure Displaying the entire image side-by-side (2) When re-taking with a slight change in focus distance Enlarging and displaying the vicinity of the focus position (3) Re-taking with a different composition Case Consider displaying one image at full angle of view and switching display target images Even if you perform this kind of operation, the user must first start by grasping the shooting parameters and the difference between the images. It takes a lot of work to compare and examine images.

  In order to deal with such a problem, Japanese Patent Application Laid-Open No. H10-228707 selects an overall unit that handles a plurality of images that meet a predetermined condition as one image group, and selects at least one representative image for each image group. The technology is disclosed. According to this technology, it is possible to provide an apparatus that automatically groups images with similar compositions and automatically selects and presents high-quality photographs.

[Example 1]
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a configuration diagram of a recording / reproducing apparatus 100 according to an embodiment of the present invention. The recording / reproducing apparatus includes an optical system 101, an imaging unit 102, a camera shake correction control unit 103, an image acquisition unit 104, an imaging parameter acquisition unit 105, a work memory 106, an inter-image translation / rotation estimation unit 107, an imaging parameter difference extraction unit 108, It comprises a difference evaluation unit 109, an image comparison display control unit 110, an operation / display unit 111, a JPEG CODEC 112, a CPU (Central Processing Unit) 113, and a recording unit 114.

  The optical system 101 captures and forms a subject image at the time of shooting, and has a correction optical system (not shown) for correcting camera shake. The imaging unit 110 includes an image sensor / image processing unit (both not shown), takes a subject image formed on the image sensor through the optical system 101, and performs photoelectric conversion and image processing. The camera shake correction control unit 103 includes a camera shake detection unit (not shown) that detects the amount of camera shake, and performs camera shake correction by controlling the operation of the correction optical system included in the optical system 101.

  In addition, it has a function of calculating the amount of camera shake that has not been corrected by the correction optical system when the amount of camera shake during shooting is large (the amount of camera shake correction remaining). The image acquisition unit 104 acquires the image data recorded in the recording unit 114. The shooting parameter acquisition unit 105 acquires parameters at the time of shooting the image data recorded in the recording unit 114. The work memory 106 is a working memory for processing image data and the like. The inter-image rotation / translation estimation unit 107 compares two images and estimates the rotation / translation amount between the images.

  The shooting parameter difference extraction unit 108 acquires shooting parameters for two images and extracts the difference. The difference evaluation unit 109 compares and evaluates the difference between the images and the imaging parameters extracted by the inter-image rotation / translation estimation unit 107 and the imaging parameter difference extraction unit 108. The image comparison display control unit 110 controls a display UI for the user to compare images. The operation / display unit 111 includes a physical button and a touch panel LCD (not shown), displays an image and a UI, and performs a UI operation by touching the physical button or the touch panel. The JPEG CODEC 112 compresses / decompresses image data. The CPU 113 performs processing by software. The recording unit 114 has a nonvolatile memory (not shown), and records / reproduces image data and imaging parameters of the image data.

(Recording function)
The recording / reproducing apparatus 100 has a still image recording function. At the time of recording, the image data acquired by the imaging unit 102 is encoded by the JPEG CODEC 112 and then recorded in the recording unit 114. When recording image data, settings (imaging parameters) when the image data is captured are recorded. The shooting parameters include a shutter speed, an aperture value, a focus position on the image, a focus distance, and a camera shake correction remaining amount.

(Playback function)
The recording / reproducing apparatus 100 has a still image reproduction function. During reproduction, the image data read from the recording unit 114 by the image acquisition unit 104 is decoded by the JPEG CODEC 112 and then displayed on the LCD of the operation / display unit 110.

(Comparison display function)
The recording / reproducing apparatus 100 also has a function (image comparison display function) for comparing and displaying two images selected by the user among images read from the recording unit 114. In the image comparison display function, a display method suitable for comparison is automatically selected from the imaging parameters of the two images and the difference between the images themselves for display. The user can change the rating score of each image on the comparison display screen based on the result of the comparison study.

(Rotation / translation estimation between images)
An inter-image translation / rotation estimation unit 107 estimates rotation and translation amount as a difference between images for use in the image comparison display function. For translation, one of the two images is translated in parallel to estimate the amount of movement that matches the two images. For rotation, one of the two images is rotated to estimate the rotation angle that matches the two images. In addition, reliability is calculated for each of these estimated amounts. For example, when two images having no correlation do not match due to rotation or movement, the reliability of the result of estimating the rotation / translation amount is low. For each of rotation and translation, the estimated difference amount is output when the reliability is equal to or higher than a certain level. Otherwise, the result of the difference amount is output as zero.

(Details of image comparison display function)
A flow of processing performed by the image comparison display control unit 110 when performing image comparison display will be described. First, selection processing of two images to be selected is performed. The image selection operation is performed using a UI on a touch panel LCD included in the operation / display unit 111.

  In the image comparison display function, the user first selects one image as a reference for comparison. When another image to be compared is selected, comparison display is performed for the two selected images. An image for image selection is displayed using a playback function.

  FIG. 2 shows a UI display example 200 for selecting the first image. This represents a state in which the user touches and selects a desired image 202 on the image list 201. By pressing the button 203 in this state, the screen transitions to the second image selection UI. When the button 204 is pressed, the image selection can be canceled and finished.

  FIG. 3 shows a UI display example 300 for selecting the second image. In this figure, the image selected in FIG. 2 is fixedly displayed as shown in the image display 301, while a UI 302 for selecting the second image to be compared is displayed. The UI 302 can scroll to the previous and next images by a touch operation. After scrolling so that the desired image is in the center, a button 303 is pressed to perform comparison display of the images. If the button 304 is pressed, the screen can return to the first selection screen. Two images to be compared are selected by the above UI operation.

(Example based on representative difference)
FIG. 4 shows the flow of processing until the selected two images are compared and displayed. First, the image acquisition unit 104 reads two images from the recording unit 114, decodes them by the JPEG CODEC 112, and stores them in the work memory 106 (S401 in FIG. 4). Next, the shooting parameter acquisition unit 105 reads out shooting parameters corresponding to the two images from the recording unit 114 and stores them in the work memory 106. The shooting parameter difference extraction unit 108 extracts the difference between the shooting parameters of the two images (S403 in FIG. 4). The inter-image translation / rotation estimation unit 107 estimates the translation / rotation between the two images (S404 in FIG. 4).

  The difference evaluation unit 109 evaluates the imaging parameter and the translation / rotation amount between images, and determines the most main difference (representative difference) from these (S405 in FIG. 4). Based on the determined representative difference, the two images are compared and displayed on the LCD of the operation / display unit 111 (S406 in FIG. 4).

(Difference weighting)
Details of the difference extraction performed by the inter-image translation / rotation estimation unit 107 and the imaging parameter difference extraction unit 108 will be described. In order to determine the representative difference, it is necessary to compare different differences, but the shooting parameters to be compared and the translation / rotation amounts between images are of different dimensions, and it is not possible to simply compare their magnitudes Can not. For example, when the focus distance is expressed as the distance to the subject, the distance from the closest end to infinity is handled, which is not suitable for comparison. In view of the above, in the present embodiment, the numerical value is expressed as follows according to the type of difference.

  The inter-image translation / rotation estimation unit 107 quantifies the number of pixels of the translation amount between images as a translation difference between images, and the rotation angle (degree) between images as a rotation difference. Further, the photographing parameter difference extraction unit 108 takes the logarithm of the ratio of exposure time as the difference in exposure, the difference in the size of the remaining correction component converted into the number of pixels on the image as the difference in the remaining camera shake correction, and the focus distance As the difference, the rotation position of the focus lens drive motor is normalized as a difference in the range from the near end to the infinity, and is converted into a numerical value.

(Difference comparison-comparison display)
The difference evaluation unit 109 performs comparison by multiplying the various difference amounts digitized as described above by a predetermined weighting coefficient.
Various differences

And the corresponding weighting factor

Is described. The range of the value of i is up to (the number of difference types minus 1). At this time,

The i-th difference that maximizes the value of is the representative difference. However, in cases where there is a large amount of difference other than the representative difference, it may not be appropriate to compare only the representative difference.
When the value exceeds a certain value, a result of excessive difference is output.

  The image comparison display control unit 110 selects a comparison display method according to the output result of the difference evaluation unit 109, and performs comparison display on the LCD of the operation / display unit 111. This will be described with reference to FIG. When there is no representative difference such as the same image (No in FIG. 5 SS501), the default comparison display method “display side by side on the entire screen” is performed (FIG. 5 SS511). If there is a representative difference (FIG. 5 Step S501 Yes), if there is an excessive difference (No in SS502 in FIG. 5), a default comparison display is performed (S511 in FIG. 5). When the representative difference is rotation between images (S503 in FIG. 5), all the angles of view are displayed side by side with grid auxiliary lines (S504 in FIG. 5).

  When the representative difference is translation between images (No in FIG. 5 S503, FIG. 5 S505 Yes), one image is displayed at all angles of view, and the user can switch images (S506 in FIG. 5). When the representative difference is the camera shake correction remaining (No in FIG. 5, No in FIG. 5 S 507), the vicinity of the focus position is enlarged and compared and displayed (FIG. 5S 508).

  Similarly, when the representative difference is the focus position and the difference in the focus distance is equal to or smaller than the predetermined value (S507 No, S509 Yes, S510 Yes in FIG. 5), the vicinity of the focus position is enlarged and comparison display is performed (S508 in FIG. 5).

  When the representative difference is the focus position and the difference in the focus distance exceeds a predetermined value (S507 No in FIG. 5, S509 Yes, FIG. 5 S510 No), the images are displayed side by side at all angles of view (S511 in FIG. 5).

  If none of the above-mentioned representative difference types is applicable (No in FIG. 5 S507), for example, if it is exposure, the images are displayed side by side at all angles of view (S511 in FIG. 5).

(Explanation of display examples)
