Patent ID: 7777793

Claim:
An image capture apparatus, comprising: an image pickup element that generates an analog signal; an A/D conversion unit that converts the analog signal generated by said image pickup element to a digital signal; an operation unit that performs a predetermined operation on a plurality of digital signals converted by said A/D conversion unit from the analog signals output from a plurality of optical black pixels of said image pickup element; a selection unit that selects and outputs one of the digital signals converted by said A/D conversion unit and a result of the predetermined operation by said operation unit; a setting unit that sets an output start timing of the result of the predetermined operation by said operation unit, in a case where the digital signals converted by said A/D conversion unit from the analog signals which are read out from said image pickup element to generate dark correction data are output; and a control unit that controls said selection unit such that the digital signals converted by said A/D conversion unit from the analog signals read out from a plurality of pixels of said image pickup element are output by said selection unit before the output start timing set by said setting unit is reached, and the result of the predetermined operation performed on the output digital signals by said operation unit is output by said selection unit when the output start timing set by said setting unit is reached.
