PROBLEM TO BE SOLVED: To promptly and surely give an instruction for a zoom magnification and zoom speed desired by a user with touch operation.SOLUTION: A zoom control device is provided that includes: touch detection means (touch panels 106a, 70a) for detecting touch operation; and control means (CPU 151, system control unit 50) for performing control in such a manner that, when the touch detection means detects that a plurality of points are touched and detects touch operation for moving the touch positions, zooming is performed with a zoom magnification corresponding to a change of a distance between the plurality of touch points and at a zoom speed corresponding to a rotation angle of a straight line formed by the plurality of touch points.SELECTED DRAWING: Figure 2 |
