Image sensor and image capture apparatus

An image capture apparatus comprising:

• an image sensor in which a length of a pixel portion in a first direction is longer than a length of the pixel portion in a second direction orthogonal to the first direction, wherein the pixel portion includes:
• a plurality of microlenses arranged in a matrix in the first direction and the second direction, and
• a plurality of photoelectric conversion portions provided for each microlens of at least some of the plurality of microlenses and configured to perform photoelectric conversion on light that has entered the photoelectric conversion portions via the each microlens,
• wherein the plurality of photoelectric conversion portions are arranged in at least one direction of the first direction and the second direction, and
• wherein an electric charge crosstalk rate between a plurality of photoelectric conversion portions arranged in the first direction is higher than an electric charge crosstalk rate between a plurality of photoelectric conversion portions arranged in the second direction;
• and
• a processing unit that processes signals output from the image sensor,
• wherein the processing unit is implemented by one or more processors, circuitry or a combination thereof.
