Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to personal computers and workstations, and particularly to a display processing device that displays an enlarged image.

[Conventional technology]

When moving from a partially enlarged image of an image to be processed to a partially enlarged image of another area of the same image to be processed, conventional devices move from the center of the icon to the specified point by specifying a point on the parallel movement valuator icon. A partial enlarged image of the area after the movement was displayed according to the movement amount according to the direction and distance of the area.

However, it is difficult to intuitively judge which region of the image to be processed is displayed by the partially enlarged image after movement, and it is difficult to quickly display the part to be enlarged, so these points have not been considered. There wasn't.

In addition, as a conventional example related to the present invention, for example, Hitachi r HI T A C2 [330 Graphinks Work Station] June 1986 (1st edition) 263
0-10-001. There are PL59 to P160.

[Problem to be solved by the invention]

The above-mentioned conventional technology displays a partially enlarged image after movement by giving the direction and amount of movement relative to the currently displayed partially enlarged image, so this enlarged image indicates which region of the image to be processed. There was a problem in that it was difficult to intuitively judge whether the image was enlarged or to quickly specify the part to be enlarged.

SUMMARY OF THE INVENTION An object of the present invention is to provide a display processing device that can intuitively and quickly specify a portion of an image to be processed that is to be enlarged.

[Means to solve the problem]

The above purpose is to provide a means for storing in which area on the screen the entire reduced image of the image to be processed is displayed, and an area indicating which area of the image to be processed is displayed by the currently displayed partially enlarged image. displaying an instruction frame on the overall reduced image;
This is achieved by providing a means for calculating where on the entire reduced image the region designation frame after movement is located based on the region designation frame movement information provided by the coordinate input device.

[Effect]

Memorize in which area on the screen the entire reduced image of the image to be processed is displayed, and input the coordinates of the area designation frame indicating the area of the enlarged partial image displayed on the entire reduced image relative to the image to be processed. Calculate and display the display device on the overall reduced image of the area instruction frame after movement from the area instruction frame movement information imported from the device, and at the same time compare it with the display position of the stored overall reduced image on the screen and determine the processing target. By calculating which region of the image is indicated, a partially enlarged image of the region indicated by the moved region designation frame is displayed.

This allows the user to intuitively and quickly specify the portion to be enlarged using the area designation frame shown in the entire reduced image of the image to be processed.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. .

Figure 2 shows the processing target image to be processed, and the image is 5040 dots in the
It is composed of 128 dots (hereinafter referred to as dots in the X-axis direction x dots in the Y-axis direction), and the user can enlarge any part of the image to be processed.

As shown in Figure 1(a), the resolution is 1.280 x 1.
In the display screen 1 of 024 dots, a partial enlarged image 2 of 720 x 840 dots where the upper left of the image starts at display screen absolute coordinates 5 (0, 0) and an area instruction of 420 x 344 dots whose upper left starts with the same < (860, 680) Display image 3 at the same time. The area instruction image 3 is the processing target image 50 in FIG.
This is an image obtained by reducing the size of 40 x 41.28 dots to 420 x 344 dots by 1/12 on both the X and Y axes.

Also, the absolute coordinates 5 (860, 680) of the upper left display screen of the area designation image 3 are stored.

In FIG. 1(a), the area indicated by the area specifying frame 4 displayed on the area specifying image 3 is enlarged to display a partially enlarged image 2. In FIG. Here, if information is input from the coordinate input device to move the area designation frame 90 dots in the X-axis direction and 135 dots in the opposite direction to the Y-axis direction, then the absolute coordinates of the lower left display screen of the area designation frame 4 before movement are input. 5 (1060,985)
Add 90 dots in the X-axis direction to the value in (Figure 1 (a)), Y
By subtracting 135 dots in the axial direction, the area is displayed so that the lower left of the area designation frame is at absolute coordinates 5 (1150, 850) on the display screen, as shown in FIG. 1(b). At the same time, a partially enlarged image 2 of the area indicated by the moved area designation frame is displayed using the calculation method described below.

First, when calculating the center coordinates of the area designation frame 4 after movement, the display screen absolute coordinates 5 at the lower left of the area designation frame 4 are (1150, 85
0), 60X because the upper right is (1210,780)
An area of 70 dots is indicated, and the center is (1180, 815), which is 30 dots in the X-axis direction from the lower left coordinate and 35 dots in the opposite direction to the Y-axis. Here, take out the absolute floor and mark on the upper left display screen of the area indication image 3 that was previously stored, and calculate the center coordinates and the X-axis direction of the area indication frame 4 after movement, which were just calculated.
Comparing how many dots are apart in both the Y-axis direction, the upper left coordinates of the area indication image 3 are (860, 680), so 320 dots in the X-axis direction and 135 dots in the Y-axis direction.
Although they are far apart, as shown earlier, the area indication image is an image that has been reduced to 1/12 on both the X and Y axes of the image to be processed in Figure 2, so the point indicated by the center of the area indication frame after movement is actually When converted to the coordinates of the image to be processed, both the X-axis and Y-axis are 12 times larger, 3840 dots in the X-axis direction and 1620 dots in the Y-axis direction.The area to be displayed as partial enlarged image 2 is area f!
Since it is 12 times the distance between the i-designated frame and its center, there will be 30x12 = 360 dots in the X-axis direction and the opposite direction, and 35x12 = 420 dots in the Y-axis direction and the opposite direction. (Fig. 3) Also, the display area of the partially enlarged image 2 is 720
Since the size is 840 dots, and each of the X and Y axes is 12 times larger than the area designation frame 4 (60 x 70 dots), the area shown in FIG. 3 can be displayed as it is as the partially enlarged image 2. This completes the series of processing.

〔Effect of the invention〕

According to the present invention, when moving the display from an enlarged image of one part of an image to be processed to an enlarged image of another part, the part to be enlarged can be directly viewed while viewing the partially enlarged image and the entire reduced image of the image to be processed. Since it can be specified, the part to be enlarged can be specified quickly and accurately, and the enlarged part can be quickly recognized, which has the effect of reducing the mental burden on the operator.
