- the size of the display size in the horizontal and vertical directions is XDISPLAYSIZE and YDISPLAYSIZE, respectively.
- the coordinates (xpositionO, ypositionO) in the input image data corresponding to the upper left point of the displayed display image data are set.
- the input image data is received from the image input device 1801, and is stored in the input image data buffer 1805 (S19 ⁇ 2).
- the control unit 1806 detects input from the user (S1903).
- the squared distance dist between the position (xposition, yposition) requested to be displayed by the user and the current display position 11L (xpositionO, ypositionO) is calculated (S19). 0 5).
- the distance may be used.
- dist is not larger than a certain fixed square distance dist-th (here, set to 10000), it is determined that the movement distance is small, and the movement processing end flag flag used to determine the movement processing end is set.
- Set to 1 and display the display position requested by the user (S1906)
- the image data is created by the display image data creation processing unit 1807, and the created display image data is stored in the display image data buffer 1808 (S1908).
- the contents of the display image data are displayed on the display device 1804 (S190). Thereafter, if the movement processing end flag ag is 1, it is determined that the movement processing has been completed (S 1991).
- control unit 1806 controls the display image data creation processing unit 1807 to create data of a plurality of images to be displayed on the display device 1804.
- the image is created so that the position (xposition, yposition) or scale arate in the input image data is slightly different.
- the created data is sequentially output to the display device 1804 by the control unit 1806 through the display image data buffer 1808.
- the control unit 1806 determines the output order of the data so as to obtain the effect described later, and is configured as a group of data.
- the control unit 1806 sets the movement processing end flag flag to 0, and displays the information of the last step on the display image. Before passing the data to the data creation processing unit 1807, the movement processing end flag flag is set to 1.
- FIG. 17 shows the region A where the display image data position (xpositionO, ypositionO) is the upper left point and the region B where the display image data position (xposition, yposition) specified by the user is the upper left point.
- the positional relationship and each area are shown.
- Fig. 18 shows the display image of the destination specified by the user based on the display image data position (area A).
- FIG. 8 is a diagram illustrating a change in an image area displayed when a movement process is performed up to an image data position (area B).
- the center of gravity of the display image data area is fixed as much as possible.
- the display area is widened (zoomed out) in multiple steps until the display data is input from the area A until the entire display data is displayed (for example, arate is set to 0). . 05 in steps).
- the display image data is reduced.
- the display image data narrows (zooms in) the display image data area in a plurality of steps up to the destination display image data area B (for example, increases arate by 0.05 in increments).
- the display image data is enlarged.
- the display area is expanded from the display area of the current display data in multiple steps. Before the entire input image data becomes the display area, stop expanding the display area, and then move in multiple steps to an area that includes the user-specified position according to the size of the display area. As shown in the figure, the display area may be narrowed in a plurality of steps (the image is enlarged) up to a different destination area specified by the user. In addition, it is also possible to move to the position specified by the user in multiple steps without performing the enlargement and reduction steps and keeping the same magnification.
