METHOD FOR DRIVING IMAGE CAPTURE DEVICE, IMAGE CAPTURE DEVICE, AND IMAGE CAPTURE SYSTEM

摘要

An image capture device includes multiple pixels, each of which has multiple photoelectric conversion elements. Each of first pixels which are some of the pixels outputs a signal based on charges obtained by adding together the charges generated in the photoelectric conversion elements. Each of second pixels outputs a signal based on charges generated by a photoelectric conversion element disposed at a first position, without outputting charges generated by a photoelectric conversion element disposed at a second position among the photoelectric conversion elements. Each of third pixels outputs a signal based on charges generated by the photoelectric conversion element disposed at the second position, without outputting a signal based on charges generated by the photoelectric conversion element disposed at the first position.

1. A method for driving an image capture device including a plurality of pixels, each of the plurality of pixels including a microlens and a plurality of photoelectric conversion elements, the plurality of photoelectric conversion elements generating respective charges based on light passing through the microlens and being disposed at a first position and a second position with respect to the microlens in such a manner as to receive light passing through different respective pupils in an optical system, the pupils being different from each other, the method comprising:
supplying a common voltage to the plurality of photoelectric conversion elements such that the plurality of photoelectric conversion elements are depleted; in one vertical scanning period in which rows in which the plurality of pixels are arranged are vertically scanned, by using a first pixel, outputting a signal based on charges obtained by adding together the charges generated by the plurality of photoelectric conversion elements; by using a second pixel, outputting a signal based on charges generated by the photoelectric conversion element disposed at the first position among the plurality of photoelectric conversion elements, without outputting a signal based on charges generated by the photoelectric conversion element disposed at the second position among the plurality of photoelectric conversion elements; and by using a third pixel, outputting a signal based on charges generated by the photoelectric conversion element disposed at the second position among the plurality of photoelectric conversion elements, without outputting a signal based on charges generated by the photoelectric conversion element disposed at the first position among the plurality of photoelectric conversion elements.
