US Patent 9826175 Image pickup apparatus and photographing apparatus including the same

Provided is an image pickup apparatus capable of reading out and outputting pixel data of a partial area of a rolling shutter type image sensor. The image pickup apparatus includes: a readout condition setter setting a readout condition for pixel data readout control from the image sensor; a charge time setter setting charge time of the image sensor; a skip setter setting, based on the readout condition, areas in which processing concerning one of readout and charge in an image pickup area of the image sensor is skipped; a controller controlling a charge of the image sensor and readout from the image sensor so as to achieve constant charge time of the image sensor within one frame based on the charge time and the areas set by the skip setter; and an image signal output unit outputting a pixel signal read out by the controller.
