Description

  The present invention relates to an image comparison display method for displaying two images side by side on a monitor screen, and more particularly to an image comparison display method, an apparatus thereof, and an image capable of easily comparing two images of different sizes. The present invention relates to a comparison display program.

  Digital cameras have become widespread, and a large number of captured images are taken into a personal computer and stored in a large-capacity storage medium such as a hard disk. Further, each image is trimmed on the monitor screen of a personal computer or image processing is performed with retouching software. As a result, processed images are now stored together.

  However, on the other hand, when a large number of images are accumulated, it becomes difficult to select a favorite image from among them. For this reason, for example, in the prior art described in Patent Document 1 below, the monitor screen is divided into two images so that two images can be displayed side by side. This makes it easy to judge visually.

JP 2000-298467 A

  When the display target image is displayed on the monitor screen using image viewer software or the like, usually, a fit display that displays the display target image in the full display frame of the screen or the display window is employed.

  However, when this fit display is used when each of the two images to be compared is displayed on the first divided screen and the second divided screen which are divided into screens, the comparison may be difficult. For example, an image of a flower bed is displayed on the first divided screen, an image of one flower cut out from the image of the flower bed is displayed on the second divided screen, and a flower image that is more beautiful than the image of the flower is an image of the flower bed. When comparing whether or not the image remains in the second split screen, if the image of the flower is enlarged with the fit display, it becomes difficult to compare the image of the flower and the image of the flower in the flower bed. End up.

  An object of the present invention is to provide an image comparison display method, an apparatus for the same, and an image comparison display program capable of easily comparing even images of different sizes.

  An image comparison display method, an apparatus therefor, and an image comparison display program according to the present invention provide an image comparison display program that divides a monitor screen into a plurality of divided screens and displays different images on the divided screens. When the sizes are different, the resolution of each image is automatically made the same and displayed on each divided screen.

  With this configuration, the display resolutions of the two images to be compared are matched without any troublesome operation, so that the two images can be easily compared.

  An image comparison display method and apparatus and an image comparison display program according to the present invention are displayed on one divided screen in an image comparison display in which a monitor screen is divided into a plurality of divided screens and different images are displayed on the divided screens. In the case of changing an existing image to another image, the resolution of the different image is automatically matched with the resolution of the image displayed on the other divided screen before being displayed.

  With this configuration, the display resolutions of the two images to be compared are matched without any troublesome operation, so that the two images can be easily compared.

  The image comparison display method and apparatus and the image comparison display program according to the present invention display an enlarged display or reduced display or scroll display of a display image of one divided screen, It is characterized in that it is displayed in a reduced size or scrolled for the same movement direction movement distance.

  With this configuration, even when one of the image displays is changed, both images can be easily compared.

  According to the image comparison display method and apparatus and the image comparison display program of the present invention, the enlargement display or the reduction display at the same magnification or the scroll display of the movement distance in the same moving direction is performed when an interlocking instruction is input. When there is no input, enlargement display, reduction display, and scroll display are performed only on the display image of the divided screen for which the enlargement instruction, the reduction instruction, and the scroll instruction are given.

  With this configuration, the user can arbitrarily set the linked image change and the unlinked image change.

  The image comparison display method and apparatus and the image comparison display program according to the present invention determine a common image size in which both the first image and the second image are included, and the image is smaller than the common image size. In this case, by adding solid display data around the image, the first and second images are made the same size as the common image size, and each is made a display image, and is cut out from the display image. The image resolution is automatically made the same by displaying the image on each of the divided screens.

  With this configuration, it is easy to match the display resolutions of both images.

  The image comparison display method and apparatus and the image comparison display program according to the present invention link the first image displayed on the first divided screen and the second image displayed on the second divided screen. When the first image displayed on the first divided screen after the enlarged display, the reduced display, or the scroll display is changed to the third image, the display image of the second divided screen is changed. The pixel coordinate of the cutout frame of the display image in the common image size obtained from the second image and the third image is obtained, and the common image size is obtained in the same cutout frame as the pixel coordinate. A display image is cut out from the third image and displayed on the first divided screen.

  With this configuration, even if one image is changed after enlarging, reducing, and scrolling processing, the display resolution and position of the other image remain fixed, and the changed image is also displayed at the corresponding position with the same resolution. Therefore, it is easy to compare both images.

  According to the present invention, since both images are automatically displayed with the same resolution, comparison is easy even for images of different sizes.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a configuration diagram of an image comparison display device according to an embodiment of the present invention. This image comparison display device is realized by causing an ordinary personal computer or the like to execute an image comparison display program.

  The image comparison display device according to the present embodiment includes a high-speed central processing unit (CPU) 11, a main memory (RAM) 12, a ROM 13 storing an initial program, a keyboard 14 and a mouse as input devices, and the like. A display control unit 20 to which a pointing device 15, an FD drive 17 to which an external storage medium such as a flexible disk 16 is connected, a hard disk (HDD) 18 as a large-capacity storage medium, and a monitor display device 19 having a screen 3 are connected. And an interface (IF) unit 22 for connecting the digital camera 21 and a bus 23 for connecting them together.

  FIG. 2 is a conceptual explanatory diagram of an image comparison display method executed by the image comparison display device of the present embodiment. An example will be described in which image A is displayed on the first divided screen and image B is displayed on the second divided screen. In this example, the image A and the image B have the same aspect ratio, but the image size of the image B is smaller than the image size of the image A. Now, the resolution of the image A, that is, the image size is 800 (horizontal) × 600 (vertical) dots, and the resolution of the image B, that is, the image size, is 640 (horizontal) × 480 (vertical) dots.

  In the present embodiment, when the image sizes of the two images to be compared and displayed are different, the common image size Mab of both images is determined. The common image size is an image size in which both images are included. In the case of the images A and B, 800 (horizontal) × 600 (vertical) dots are determined as the common image size Mab.

  Since the image size of the image A matches the common image size Mab, the image data of the image A is used as it is as a display image. However, the image size of the image B does not match the common image size Mab. Therefore, in this example, image data of 800 (horizontal) × 600 (vertical) dots as a whole is created by adding data B ′ that is displayed in gray, for example, around image B around image B, This is the display image for image B.

  Then, as shown in FIG. 3, the display image of image A is displayed on the first divided screen 1 of the monitor screen 3, and the display image of image B is displayed on the second divided screen 2. Thereby, the resolution of the image A displayed on the 1st division | segmentation screen 1 and the image B displayed on the 2nd division | segmentation screen 2 becomes equal, and the comparison of both the images A and B becomes easy. That is, the image B is not displayed enlarged on the second divided screen 2 by the fit display.

  In FIG. 2, the common image size Mab is determined from the images A and B having the same aspect ratio. However, the common image size Mab can be determined from the images A and B having different aspect ratios. FIG. 4 is an explanatory diagram thereof.

  The image size of the image A in the example shown in FIG. 4 is 800 (horizontal) × 600 (vertical) dots, and the image size of the image B is 480 (horizontal) × 640 (vertical) dots. In this case, an image size of 800 (horizontal) × 640 (vertical) dots is determined as a common image size Mab including both images A and B. Then, the data A ′ displayed in gray on the upper and lower sides of the image A is added to form a display image for the image A, and the data B ′ displayed in gray on the left and right of the image B is added to the left and right sides thereof. Thus, the image B is displayed.

  FIG. 5 is a diagram illustrating an example in which the image A created in FIG. 4 is displayed on the first divided screen 1 and the image B is displayed on the second divided screen 2. Even in this case, since the images A and B are both displayed as images having the same resolution, an intuitive comparison is possible.

  Here, since the common image size is generated from two images A and B having arbitrary sizes, the aspect ratio and size thereof are the same as the aspect ratio and size of the first and second divided screens 1 and 2. It is normal to be different. Therefore, in such a case, areas to be displayed on the divided screens 1 and 2 are extracted from the display images of the images A and B having the common image size by the cut frames 4a and 4b having the same size (see FIG. 4). Cut out and display.

  When an enlarged display instruction, a reduced display instruction, a scroll display instruction, or the like is input to the image A displayed on the first divided screen 1, the display of only the image A may be enlarged, reduced, or moved. However, when the input operation of the interlock instruction is performed, both the images A and B are enlarged and reduced at the same magnification, and the screen is scrolled in the same movement direction and movement distance. This makes it easy to compare the images A and B even when the images A and B are enlarged, reduced, or scrolled.

  FIG. 6 is a flowchart showing a processing procedure of the above-described common image size determination processing for images A and B and interlocking processing at the time of enlargement / reduction display. Although the scroll display interlocking process is omitted, this can be performed in the same manner as the enlargement / reduction process.

  First, the width data and height data of the image A are acquired, and the width data and height data of the image B are acquired (step S1). Next, the larger width data W of the width data of the images A and B and the larger height data H of the height data of the images A and B are obtained to obtain the common image size Mab. The image size W × H is determined (step S2).

  In the next step S3, display images A and B having a common image size W × H are created from the images A and B. In the example described with reference to FIG. 2, when creating the display image B from the image B, the gray solid display data is added around the image B. However, the image B does not have to be the center, and the image B Gray solid display data may be added so that the positions are biased. These display images A and B are temporarily stored in an image memory provided in the display control unit 20 of FIG. 1 separately from the images A and B.

  In the next step S4, the display images A and B created in step S3 are displayed on the divided screens 1 and 2 (FIGS. 3 and 5), respectively. At this time, if necessary, the display target area is cut out from the display images A and B using the frames 4a and 4b described in FIG.

  In the screen display of FIGS. 3 and 5, it is assumed that the interlock button 5 in the screen 3 is clicked using, for example, a mouse cursor. In step S5, it is determined whether or not the enlargement instruction button 6 among the operation buttons on the screen 3 has been clicked. If an enlargement instruction is input, the process proceeds to step S7 via step S6, and the enlargement instruction is input. If not, the process proceeds to step S7 as it is. In step S6, the display image A is enlarged and displayed on the divided screen 1, and the display image B is enlarged and displayed on the divided screen 2 at the same magnification as the enlargement ratio of the display image A.

  In step S7, it is determined whether or not the reduction instruction button 7 has been clicked. If a reduction instruction is input, the process proceeds to step S9 via step S8. If a reduction instruction is not input, the process proceeds to step S9. In step S8, the display image A is reduced and displayed on the divided screen 1, and the display image B is reduced and displayed on the divided screen 2 at the same magnification as the reduction ratio of the display image.

  In step S9, it is determined whether or not the display is to be continued. If the display is to be continued, the process returns to step S5, and the display is terminated when there is an instruction input for not continuing the display.

  As described above, according to the present embodiment, two images having the same resolution are displayed on each divided screen, so that image comparison can be easily performed without troublesome operations.

  Next, when the image A and the image B are displayed on the divided screens 1 and 2 of the same screen 3 as described above, an instruction to change the display image of the divided screen 1 from the image A to the image C is input. The case will be described.

  As shown in FIG. 7, an arbitrary area in the image B is cut out with the cutout frame 4b and enlarged and displayed on the split screen 2, and the arbitrary area of the image A is cut out and divided with the same cutout frame 4a as the cutout frame 4b. Assume that an enlarged display is made on the screen 1. When the display image of the divided screen 1 is changed from the image A to the image C, for the user, the image C of the divided screen 1 corresponds to the image B while the display of the image B of the divided screen 2 is fixed. In view of image comparison, it is preferable to display an enlarged image cut out by C, that is, the cut frame 4c corresponding to the cut frame 4b.

  Therefore, in the present embodiment, when the above interlocking instruction is input, for example, the pixel coordinates (sx, sy) and the lower right corner of the upper left corner point b1 of the cutout frame 4b with the upper left corner point b0 of the image B as the origin. The pixel coordinate (ex, ey) of the point b2 is obtained, the height bH and the width bW of the image B are obtained, and the upper left corner point M0 of the common image size Mbc of the image B and the image C is extracted as the origin The same cutout frame 4c (upper left corner point c1, lower right corner point c2) as the frame 4b is calculated, and the display image C is cut out with the cutout frame 4c and displayed on the divided screen 2.

  FIG. 8 is a flowchart showing a processing procedure of the interlocking display process described in FIG. First, in step S11, the divided screen 1 is set as the main screen (display fixed side screen), the divided screen 2 is set as the width screen (display change side screen), the change flag is turned off, and the process proceeds to step S12.

  In step S12, it is determined whether or not there is an instruction to change the image A being displayed on the divided screen 1 to another image C. If this determination result is negative, it is determined in the next step S13 whether or not there is an instruction to change the image B being displayed on the divided screen 2 to another image C.

  If the determination result in step S13 is negative, the process proceeds to step S14 to determine whether or not the change flag is on. If the determination result is negative, the process proceeds to step S15 and whether or not to continue the display. If the determination result is affirmative, the process returns to step S12. If the determination result is negative, the process ends.

  If the result of determination in step S12 is that there is a display image change instruction input for split screen 1, the process proceeds from step S12 to step S13 via step S16. In step S16, the divided screen 2 that has not been instructed to change is the main screen, the divided screen 1 that has been instructed to be changed is the sub-screen, and the change flag is turned on.

  As a result of the determination in step S13, if there is a display image change instruction input for the divided screen 2, the process proceeds from step S13 to step S14 via step S17. In step S17, the divided screen 1 that has not been instructed to change is the main screen, the divided screen 2 that has been instructed to be changed is the sub-screen, and the change flag is turned on.

  If the determination result of step S14 is affirmative, that is, if the change flag is on, the process proceeds to step S18 to step S24, and then, step S15 is entered.

  In step S18, first, the display position of the image on the main screen is acquired, and the size (width and height) of the image on the main screen is acquired. In the example of FIG. 7, the pixel coordinates of the upper left corner point b1 and the lower right corner point b2 of the image B, the image size width bW, and the height bH are acquired.

  In the next step S19, the width and height data of the image B are read and the width and height data of the image C are read. In step S20, the larger width W of the widths of the images B and C is selected. At the same time, the larger height H of the images B and C is selected to determine the common image size Mbc. Then, in step S21, data for gray solid display is added around image B to create display image B, and data for gray solid display is added around image C as the center. Display image data C is created. The processes in steps S19, S20, and S21 are the same as steps S1, S2, and S3 in FIG.

  Next, in step S22, the pixel coordinates of the upper left corner point c1 (Sx ', Sy') and lower right corner point c2 (Ex ', Ey') of the cutout frame 4c cut out from the display image C shown in FIG. The upper left corner point M0 of the display image C is calculated as the origin.

The calculation formula is Sx ′ = sx + (W−bW) / 2.
Sy ′ = sy + (H−bH) / 2
Ex ′ = Sx ′ + (ex−sx)
Ey ′ = Sy ′ + (ey−sy)
It is.

  In the next step S23, the image C cut out by the cutout frame 4c is displayed on the divided screen 1, and the cutout frame 4b (this cutout frame 4b is newly based on the origin M0 similarly to the cutout frame 4c). The image B cut out in the same manner in step S22) is displayed on the divided screen 2. Then, the change flag is turned off (step S24), and the process proceeds to step S15.

  Thus, in the present embodiment, since the display of the image B already displayed on the divided screen 2 can be fixed, the image C can be displayed in accordance with the resolution of the image B without troublesome operations. The user can compare images easily and accurately.

  In the above-described embodiment, each of the divided screens 1 and 2 is illustrated in FIGS. 3 and 5 as a screen that does not overlap. However, two display windows that can be overlapped are respectively divided screens, and each display window is displayed. The present invention is also applicable to the case where images are displayed and compared.

  The present invention can display an image with the same resolution without troublesome operations, so that the image comparison is easy and accurate, and is useful as an image comparison display method.
