る。BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a reduced image display device of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a functional configuration of a main part of a reduced image display device according to the present invention. The reduced image display device itself is a CP
It is configured by dedicated hardware or a personal computer equipped with U, and various processes and operations to be described later are controlled by a program. Also, this program is stored in a recording medium such as a hard disk (not shown), and is read out to the memory of the reduced image display device and executed as necessary. In FIG. 1, a reduced image creating unit 2 reads electronic data such as image data, a document created by a word processor, data of spreadsheet software, and creates a reduced image. The unit to be created is, for example, the number of units to be displayed on the screen at one time. Difference determination unit 3
Calculates the degree of similarity between the plurality of reduced images created here, and if the degree of similarity is greater than a predetermined threshold value, the difference image creating unit 4 determines the area of the difference portion in the similar images. The image is cut out and the portion is displayed on the image display unit 1.
When the area of the difference portion is larger than the image size displayed on the image display unit 1 (for example, the size of the thumbnail image), the reduced image creation unit 2 creates a reduced image in the area, and the image display unit It may be displayed in 1. For example, in the case of a document image, the determination of the difference is made by identifying areas such as a character area, a character line, a photograph area, a table area, and a drawing area, and for each area, the corresponding areas of a plurality of similar reduced images There is a method to find the difference between. The method of dividing an image into areas is a common method in character recognition technology, and thus detailed description thereof is omitted. In character recognition, it is not necessary to recognize the photo area and the drawing area. Therefore, determine the area where the character exists, and determine the line direction (vertical or horizontal), line width (character size), etc. It will be decided. The difference between the reduced images is
For example, the determination may be made based on whether or not the pixel values of the pixels in the areas match. Also, the image with the largest difference may be displayed on the image display unit 1 instead of the reduced image. For example, in the case of the example shown in FIG. 3, the document 10 on the left has a large space between the character lines in the lower left areas of the two document images, and the document 11 on the right is large.
Is small. When these reduced images are created, they cannot be discriminated because the overall layout is similar. However, if there is a difference between the image 12 on the left side and the image 13 on the right side in the lower left area, the difference becomes large. Therefore,
As shown in FIG. 4, by displaying the lower left character area 11 having a large difference on the image display unit 1 instead of displaying the reduced image of the entire image, it is possible to easily identify the two images. Although an example of a character area has been described here as an area, the same applies to a photograph area, a table area, and the like.

像を表示したが、初めから差異画像を表示しても良い。Next, the operation of the reduced image display device of the present invention will be described with reference to FIG. FIG. 2 is a flowchart showing the processing of the reduced image display device of the present invention. In the figure,
First, a reduced image is created (S100). For example, when it is desired to display an original image of 1000 × 1000 pixels in an area where the displayable area of the reduced image is only 100 × 100 pixels, it is necessary to create a 1/10 reduced image. The image itself can be reduced easily by thinning out pixels. This image reduction is performed once for the number of images to be displayed on one screen, and reduced pixel data is stored. Next, the reduced images are compared (S101). Since the reduced image usually has the same number of pixels, it can be performed by comparing the pixel values of the corresponding pixels. The pixel value is a numerical value of each of RGB in a color image, a grayscale value in a multivalued image, and a 1-bit value of 0 or 1 in a binary image. Then, when the number of pixels having the same pixel value is equal to or larger than a predetermined number (threshold value), it is determined that the two images have a high degree of similarity. The reduced images are compared by brute force for the reduced images created at one time. Next, a difference image is created for the reduced image determined to have a high degree of similarity in step S101 (S102). This method, for example, recognizes areas such as characters, photographs, and figures using the technology of character recognition as described above, compares the areas, and selects an area with a large difference,
Generate an image of a predetermined size. The predetermined size means the same size as the reduced image in principle. And step S
A reduced image is displayed at 103. In this embodiment, the reduced image obtained in step S100 is displayed regardless of the degree of similarity. Then, the user is allowed to sequentially change the screen display using a mouse or the like. Thereafter, the interaction between the user and the device starts. First, the device waits for a mouse click (S10).
4). When the click is detected, it is determined whether or not the part instructing the end is clicked, and if so, the process ends (S105). If it is not finished, it is determined whether or not the portion supporting the display of the next screen is clicked (S106). If the next screen is clicked, the process proceeds to the image reduction step of step S100 to process the remaining electronic data. If a specific reduced image is clicked (S107), the difference image created in step S102 is displayed instead of the reduced image clicked (S108), and the mouse is waited for. If a specific reduced image is double-clicked, it may be processed as an instruction to display the contents of the data.
In this embodiment, the reduced image is first displayed regardless of the similarity of the reduced image, but the difference image may be displayed from the beginning.
