Abstract
An image sensor, comprising a pixel region in which a plurality of pixel units are arranged, each pixel unit having first and second photoelectric conversion portions, a first output portion that outputs, outside of the image sensor, a first signal based on a signal from the first photoelectric conversion portion of the pixel units, and a second output portion that outputs a second signal based on a signal from the first photoelectric conversion portion and a signal from the second photoelectric conversion portion of the pixel units, wherein output of the first signal from the first output portion and output of the second signal from the second output portion are performed in parallel.
Claims9
An image capturing apparatus, comprising:
- a plurality of pixels respectively comprising a plurality of photoelectric conversion portions and outputting a first voltage signal based on charges of a part of photoelectric conversion portions among the plurality of photoelectric conversion portions and a second voltage signal based on charges of the photoelectric conversion portions other than the part of photoelectric conversion portions among the plurality of photoelectric conversion portions;
- and
- a plurality of storage circuits respectively provided in one-to-one correspondence with each of the plurality of pixels and storing voltage signals based on the charges generated by the plurality of photoelectric conversion portions,
- wherein each of the plurality of storage circuits comprises a plurality of storage units including a first storage unit for storing the first voltage signal and a second storage unit for storing the second voltage signal.
