摘要

PROBLEM TO BE SOLVED: To convert at least two analog signals output from a single pixel into digital signals at high speed at a pixel used for focus detection based on a phase difference detection system or an image acquisition signal.SOLUTION: An image sensor has a plurality of comparators, at least two analog signals output from a pixel are input to the plurality of comparators respectively, and periods in which the plurality of comparators perform a comparison operation are overlapped.
