<P>PROBLEM TO BE SOLVED: To smoothly move a display area in an image as a display object. <P>SOLUTION: A range with a predetermined width, before the display limit is set in an image as a limit area. A limit area judging part 120 determines whether present display area is on the limit area. In the case the display area is on the limit area, a moving-speed determining part 122 modifies the intrinsic moving speed of the display area to the reducing direction, according to the radio of the display area entered into the limit area. A repelling-speed determining part 126 determines the moving speed of the display area for repelling the same in the direction moving away from the limit area according to the radio of the display area entered into the limit area. A frame-coordinate calculating part 124 calculates the frame coordinates of a display area to be newly displayed, on the basis of the moving speed determined by the moving-speed determining part 122 and the repelling-speed determining part 126. <P>COPYRIGHT: (C)2011,JPO&INPIT |
