PLAN DISPLAY DEVICE AND PLAN DISPLAY PROGRAM

摘要

When a plurality of enlarged/reduced images to be displayed based on a predetermined original image are displayed on a display screen, each of the enlarged/reduced images is created and displayed at a higher speed. Therefore, desired regions (vertical/horizontal target regions (532 and 533)) within an original image (690) are designated, and desired images (vertical/horizontal target images (700 and 710)) including the entire designated desired region are read from the original image, and stored separately from the original image (690). Then, an enlargement/reduction ratio (P) with respect to the original image (690) is acquired, and an enlarged/reduced original image (620) obtained by enlarging/reducing the original image (690) with the enlargement/reduction ratio (P) in both a long-side direction and a short-side direction is created and displayed on a display screen (53). Further, enlarged/reduced desired images (enlargement/reduction vertical/horizontal target images (621 and 622)) obtained by enlarging/reducing the desired images that are separately stored only in the long-side direction with the enlargement/reduction ratio (P) are created and displayed in the vertical/horizontal target regions (532 and 533) so as to be superimposed on the enlarged/reduced original image (620).

主权项

1. A drawing display device, comprising:
original image storage means for storing an original image; region designation means for designating a desired region within the original image; desired image saving means for reading a desired image comprising the entire designated desired region from the original image and storing the desired image separately from the original image; enlargement/reduction ratio acquisition means for acquiring an enlargement/reduction ratio (P) with respect to the original image; enlarged/reduced original image creating means for creating an enlarged/reduced original image by enlarging/reducing the original image with the acquired enlargement/reduction ratio (P) in both a long-side direction thereof and a short-side direction thereof; enlarged/reduced desired image creating means for creating an enlarged/reduced desired image by enlarging/reducing the desired image with the acquired enlargement/reduction ratio (P) at least in the long-side direction of the desired image; and display means for displaying the created enlarged/reduced original image and the enlarged/reduced desired image together.
