<P>PROBLEM TO BE SOLVED: To support user's operation for scrolling a display image. <P>SOLUTION: An initial image is shown on a display according to content display start operation (S10 and S12). When a user performs scroll operation on a touch panel (S14), it is monitored whether there is a shift between a reference position in a display target image and a reference position on a screen corresponding to the reference position in the image. When there is no shift, a display area is moved according to scroll operation (S16: N and S20). When there is a shift, a display area moving speed for scroll adjustment is calculated on the basis of a shift amount at each time, displacement at the moving speed is added to an actual position of the display area, and then the display area is moved to the position (S16: Y, S18, and S20). Displacement addition is continued until there is no shift irrespective of whether or not scroll operation is performed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
