Abstract

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).

Claims

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.

2. A drawing display device according to claim 1, wherein the desired region comprises a rectangular region.

3. A drawing display device according to claim 2, wherein the enlarged/reduced desired image creating means enlarges/reduces the desired image with the acquired enlargement/reduction ratio (P) in the long-side direction of the desired region and with a fixed reduction ratio (S) in the short-side direction of the desired region.

4. A drawing display device according to claim 2, further comprising movement amount acquisition means for acquiring a movement amount for changing a display range of the enlarged/reduced original image,

wherein the display means performs display by moving the enlarged/reduced original image by the acquired movement amount and moving the enlarged/reduced desired image in the long-side direction of the enlarged/reduced image by a long-side direction component amount of the acquired movement amount.

5. A drawing display device according to claim 2, wherein:

the region designation means designates the desired region within the original image by designating the rectangular region of the enlarged/reduced desired image displayed by the display means; and

the reduction ratio (S) comprises an enlargement/reduction ratio of the enlarged/reduced desired image, which is displayed by the display means when the rectangular region is designated by the region designation means, to the original image.

6. A drawing display device according to claim 2, wherein the desired image saving means reads and stores the same range as a width of the designated desired region in the short-side direction and the entire range of the original image in the long-side direction.

7. A drawing display device according to claim 1, wherein the desired image saving means reads the desired image from raster data created with a predetermined resolution when the original image is vector data.

8. A drawing display device according to claim 1, wherein:

the desired image saving means performs mask processing for the read original image and then stores the resultant as the desired image; and

the display means displays the enlarged/reduced desired image superimposed on the enlarged/reduced original image.

9. A drawing display device according to claim 8, wherein the mask processing performed by the desired image saving means comprises processing for causing the enlarged/reduced original image on a lower layer to be transparent with respect to data representing a specific color.

10. A drawing display device according to claim 1, wherein the display means comprises enlarged/reduced desired image moving means for moving a display position of the enlarged/reduced desired image to another position within the enlarged/reduced original image.

11. A drawing display program for causing a computer to implement:

a region designation function of designating a desired region within an original image stored in original image storage means;

a desired image saving function of reading a desired image comprising the entire designated desired region from the original image and storing the desired image separately from the original image;

an enlargement/reduction ratio acquisition function of acquiring an enlargement/reduction ratio (P) with respect to the original image;

an enlarged/reduced original image creating function of 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;

an enlarged/reduced desired image creating function of 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

a display function of displaying the created enlarged/reduced original image and the enlarged/reduced desired image together.
