1. An image pickup apparatus comprising:
a zoom lens for image pickup, the zoom lens having a changeable focal distance; a zoom driving section that operates to be electrically driven for changing the focal distance of the zoom lens for image pickup; a lens control section that controls driving of the zoom driving section; an image pickup device arranged at an image forming position of the zoom lens for image pickup; a mechanism section that causes the image pickup device to relatively move with respect to an optical image formed by the zoom lens for image pickup; an image processing section that generates a cut-off image corresponding to the optical image formed on a specified area of the image pickup device based on an electric signal outputted from the image pickup device, and outputs the cut-off image; an image display device that makes a display of an image output based on the cut-off image outputted from the image processing section; a touch panel provided on the image display device; a control section to which an operation signal outputted from the touch panel is inputted, and that outputs (1) a signal for driving and controlling the zoom driving section to the lens control section, (2) a drive signal for relatively moving the mechanism section, and (3) an instruction of the specified area to the image processing section; and an external apparatus communication section mutually giving and receiving information between an external apparatus and the control section; wherein when the touch panel detects a drag operation during a live view display operation of successively displaying images outputted from the image processing section on the image display device, the control section causes the specified area to relatively move with respect to the optical image according to a movement direction and movement distance of the drag operation, and when the specified position is in contact with an end part of an effective pixel area and cannot continue the relative movement in moving the specified area, the control section (1) changes the specified area to a second specified area, which is a specified area obtained by reducing the first specified area which is a current specified area with an aspect ratio of the first specified area being kept, and causes the second specified area to move, and (2) at the same time, outputs an instruction for driving the zoom driving section to the lens control section so that the focal distance of the zoom lens for image pickup is shortened according to magnification by which the first specified area is reduced to the second specified area. |
