<p><P>PROBLEM TO BE SOLVED: To quicken the moving operation of a cursor by reducing the number of times of operations necessary for moving the cursor. <P>SOLUTION: When the changing amounts of an image generated by an image generation means 18 are equal to or more than a fixed value, an image changing amount calculation means 15 transmits the changed image to a region information calculation means 13. The region information calculation means 13 divides the reception image into fixed regions, and calculates information amounts in each region, and transmits it to a cursor moving region calculation means 12. The cursor moving region calculation means 12 connects a plurality of adjacent regions with small amounts of information to generate one connection region, and stores the generated connection region and coordinate information of independent regions with large amounts of information in a moving region storage means 101. When the input operation information is the region moving operation of the cursor, a cursor moving operation control means 14 outputs the cursor moving operation control signal between regions by using the information stored in the moving region storage means 101. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
