Abstract
Abstract The present invention is directed to setting the direction and the quantity of movement by a point and to execute scrolling. A reference point is set in the display screen of the display apparatus of the electric device, in advance. When a user selects a display mode of a data processing function and designates a point within the display screen through a coordinate inputting apparatus, the device calculates a positional deviation of a designate point from the reference point as a deviation of a coordinate value, switches a display image so that an image component which is displayed at a position corresponding to the designate position is located at a position corresponding to the reference position, and scrolls the image. Further, when a point is designated successively a plurality of times as a designation point, an image which is sequentially switched is scrolled the plurality of times at predetermined time intervals. Still further, when designating is successively executed for a plurality of times, the predetermined time is shortened in accordance with the number of designating. When a display image includes a character, an approximate value of a deviation which denotes a positional deviation is found among integer-multiples of the width of a rectangular region which includes the character.
