Abstract:
1. An image pickup apparatus comprising: an image pickup section that photoelectrically converts, by an image pickup element, subject images formed through a plurality of image pickup optical systems including a first optical system and a second optical system and outputs a plurality of images corresponding to the image pickup optical systems; a first lens drive section that drives a first zoom lens included in the first optical system; a second lens drive section that drives a second zoom lens included in the second optical system; a control section that controls stepwise driving of the first lens drive section and the second lens drive section; a first counter that counts an amount of stepwise feed of the first zoom lens by the first lens drive section with respect to a predetermined reference position as a start point in accordance with control by the control section; a second counter that counts an amount of stepwise feed of the second zoom lens by the second lens drive section with respect to a predetermined reference position as a start point in accordance with control by the control section; a calculation section that calculates a magnification of the first zoom lens corresponding to the amount of stepwise feed counted by the first counter and a magnification of the second zoom lens corresponding to the amount of stepwise feed counted by the second counter; and a zoom correction information creation section that creates zoom correction information in which the amount of stepwise feed of the first zoom lens and the amount of stepwise feed of the second zoom lens corresponding to one of a plurality of magnifications of the first zoom lens and one of a plurality of magnifications of the second zoom lens close to each other are associated and records the zoom correction information on a predetermined storage medium, and further comprising a designation section which designates a zoom factor, wherein the control section identifies a first amount of feed which is the amount of stepwise feed of the first zoom lens and a second amount of feed which is the amount of stepwise feed of the second zoom lens corresponding to the zoom factor designated by the designation section from the zoom correction information and controls the first lens drive section to drive the first zoom lens by the first amount of feed and the second lens drive section to drive the second zoom lens by the second amount of feed, and wherein the zoom correction information creation section calculates a difference between the amount of stepwise feed of the first zoom lens and the amount of stepwise feed of the second zoom lens corresponding to each magnification in the zoom correction information and creates zoom correction information in which the amount of stepwise feed of the first zoom lens corresponding to each magnification and the difference are associated, and the control section identifies the first amount of feed as the amount of stepwise feed of the first zoom lens and the difference corresponding to the zoom factor designated by the designation section from the zoom correction information and controls the first lens drive section to drive the first zoom lens by the first amount of feed and the second lens drive section to drive the second zoom lens by an amount in which the difference is subtracted from the first amount of feed.
