Image sensor and image capture apparatus

An image capture apparatus comprising:

• an image sensor comprising:
• a plurality of microlenses arranged in a matrix in a first direction and a second direction orthogonal to the first direction;
• a plurality of photoelectric conversion portions, provided for each microlens of at least some of the plurality of microlenses, perform photoelectric conversion on light that has entered the photoelectric conversion portions via the respective microlens;
• and
• a readout unit that sequentially reads out signals from the plurality of photoelectric conversion units with the first direction being a main scanning direction and the second direction being a sub-scanning direction,
• wherein the plurality of photoelectric conversion portions are arranged in at least one direction of the first direction and the second direction, and
• 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 readout unit and the processing unit are implemented by one or more processors, circuitry or a combination thereof.
