Description

Technical Field

[0001] The present invention relates to a program, a method, an information processing apparatus, and an information processing system.

Background Art

[0002] Conventionally, a technique for determining whether two images are identical has been known (Patent Document 1). For example, in the field of commercial printing where high-quality printed materials are required, a user may evaluate whether the same quality of printed materials can be obtained even if the printer driver is changed due to a version upgrade. The user checks an image showing the difference between the two images to determine whether the two images are identical.

Summary of the Invention

Problems to be Solved by the Invention

[0003] However, in the conventional method, when there are multiple types of differences between two images, it has been difficult to clearly show the differences between the two images to the user.

[0004] FIG. 1 is a display example showing the difference between conventional images. The <difference image> shows the difference between the <first image> and the <second image>. Assume that the difference between the <first image> and the <second image> is two types of differences: the font and the brightness of the background color. As shown in the <difference image> of FIG. 1, when multiple types of differences are represented in the same color on one image, one difference (in the example of FIG. 1, the difference in font) is buried in the other difference (in the example of FIG. 1, the difference in the brightness of the background color). Therefore, there have been problems such as a leak occurring when the user checks the difference in the image and the user taking a long time to check the difference in the image.

[0005] Therefore, an object of one embodiment of the present invention is to improve the efficiency of the operation of checking the difference in an image.

Means for Solving the Problems

[0006] A program according to an embodiment of the present invention causes a computer to function as a display unit that displays a first image, a second image, an image showing a difference between the first image and the second image, and a type of the difference.

Advantages of the Invention

[0007] In one embodiment of the present invention, the efficiency of the operation of checking the difference between images can be improved.

[0016] <Functional block> FIG. 4 is a diagram showing the functional blocks of the information processing apparatus 10 and the information processing server 20 according to an embodiment of the present invention. The information processing apparatus 10 and the information processing server 20 include an image acquisition unit 101, a comparison unit 102, a first image display unit 103, a second image display unit 104, a difference display unit 105, a difference type display unit 106, and a difference type selection unit 107. Further, the information processing apparatus 10 and the information processing server 20 function as the image acquisition unit 101, the comparison unit 102, the first image display unit 103, the second image display unit 104, the difference display unit 105, the difference type display unit 106, and the difference type selection unit 107 by executing a program. Note that the first image display unit 103, the second image display unit 104, the difference display unit 105, and the difference type display unit 106 are also collectively referred to as a display unit 100.

[0017] The image acquisition unit 101 acquires two images, a first image and a second image, which are objects to be compared. Note that the image acquisition unit 101 can acquire the first image and the second image stored in an arbitrary storage device. For example, the first image and the second image are images represented by CMYK (four components of cyan, magenta, yellow, and black).

[0018] The comparison unit 102 compares the first image and the second image, and generates an image (hereinafter also referred to as a difference image) indicating the difference between the first image and the second image. The comparison unit 102 can generate an image (difference image) indicating the difference between the first image and the second image for each type of difference.

[0019] Here, the types of differences will be described. The type of difference may be any type of difference that occurs between the first image and the second image. For example, the type of difference may be a font, the brightness of the background color, etc., which may occur due to an upgrade of the printer driver version.

[0020] Here, the generation of the difference image will be described. For example, the comparison unit 102 compares the pixel value of the first image and the pixel value of the second image for each pixel. Further, the comparison unit 102 determines the type of difference between the first image and the second image from the comparison result of each pixel. Further, the comparison unit 102 generates a difference image for each type of difference.

[0021] The first image display unit 103 displays the first image acquired by the image acquisition unit 101.

[0022] The second image display unit 104 displays the second image acquired by the image acquisition unit 101.

[0023] The difference display unit 105 displays an image (difference image) showing the difference between the first image and the second image generated by the comparison unit 102.

[0024] For example, when the type of difference is selected by the user, the difference display unit 105 can display a difference image that is the selected type of difference.

[0025] For example, the difference display unit 105 can display an image (difference image) showing the difference using different colors for each type of difference.

[0026] For example, the difference display unit 105 can display an image (difference image) showing the difference by indicating the locations where differences occur for each type of difference.

[0027] For example, the difference display unit 105 can display an image (difference image) showing the difference by alternately displaying the first image and the second image at high speed.

[0028] The difference type display unit 106 displays the types of differences between the first image and the second image. Specifically, the difference type display unit 106 displays all the types of differences between the first image and the second image discriminated by the comparison unit 102.

[0029] The difference type selection unit 107 selects a difference image to be displayed according to the type of difference selected by the user. Specifically, the user selects a desired type of difference from the displayed types of differences. Then, the difference type selection unit 107 selects a difference image that is the type of difference selected by the user from among the difference images generated by the comparison unit 102 for each type of difference.

[0030] <Method> FIG. 5 is a flowchart showing the flow of processing for displaying a difference image (in the cases of FIGS. 6 and 7) according to an embodiment of the present invention.

[0031] In step 1 (S1), the display unit 100 displays an image to be compared. Specifically, the first image display unit 103 displays the first image acquired by the image acquisition unit 101. Also, the second image display unit 104 displays the second image acquired by the image acquisition unit 101.

[0032] In step 2 (S2), the display unit 100 displays a difference image. Specifically, the difference display unit 105 displays an image (difference image) showing the difference between the first image and the second image.

[0033] In step 3 (S3), the display unit 100 displays the types of differences. Specifically, the difference type display unit 106 displays all types of differences between the first image and the second image.

[0034] In step 4 (S4), the difference type selection unit 107 selects a difference image to be displayed according to the type of difference selected by the user.

[0035] In step 5 (S5), the display unit 100 displays a difference image. Specifically, the difference display unit 105 displays a difference image corresponding to the type of difference selected by the user in S4.

[0036] Note that S4 to S5 are repeated each time the user selects a type of difference.

[0037] <Display Example> With reference to FIGS. 6 to 10, a display example of an image (difference image) showing the difference between the first image and the second image will be described.
