ABSTRACT:
In an image information processing apparatus including a combined display and input unit, which includes a coordinate specifying unit for specifying on a screen a rectangular area containing an image and also specifiying the destination to which it is to be moved, a mode specifying unit for specifying a move mode for the rectangular area to be a paralleling mode or a rotating mode, and a position specifying unit for enabling the specification of the destination, an image paralleling and rotating system is disclosed, when the rectangular area specified by the coordinate specifying unit is displaying in the screen as moved to the destination, enabled by the position specifying unit, in accordance with instructions made by the mode specifying unit, a decision is made to determine if the coordinate specifying unit has specified a predetermined neighboring portion of a corner of the rectangular area so displayed. Further, if a result of the decision indicates that the coordinate specifying unit has specified the neighboring portion of the corner of the rectangular area, instructions from the mode specifying unit and the coordinate specifying unit are rendered to be valid. This thereby avoids an erroneous movement of the rectangular area instructed by an erroneous instruction from the coordinate specifying unit.
