IMAGE PICKUP APPARATUS THAT DETERMINES SHOOTING COMPOSITION, METHOD OF CONTROLLING THE SAME, AND STORAGE MEDIUM

摘要

An image pickup apparatus capable of generating image signals for viewing images shot in a composition (vertical or horizontal) intended by a photographer as a three-dimensional image. The apparatus has an image pickup device for converting an optical image to a picked-up image signal as an electric signal. The device includes a plurality of unit pixels, each of which has a plurality of photo diodes for converting the optical image to the picked-up image signal. When an image pickup operation is performed, a posture of the image pickup apparatus is determined, and the plurality of photo diodes in each unit pixel are grouped into a plurality of photo diode groups according to a result of the determination. A plurality of image signals are generated from picked-up image signals output from the photo diode groups, respectively.
