Image sensor

Abstract

The present invention provides an image sensor capable of high-speed readout of signals used for focus detection and signals used for image generation. [Solution] The image sensor includes a first photoelectric conversion unit that converts light transmitted through a first microlens into electric charge, a second photoelectric conversion unit arranged next to the first photoelectric conversion unit in a first direction, a third photoelectric conversion unit that converts light transmitted through a second microlens into electric charge, a fourth photoelectric conversion unit that converts light transmitted through a second microlens into electric charge and is arranged next to the third photoelectric conversion unit in a second direction intersecting the first direction, and a control unit that outputs a first added signal obtained by adding a first signal based on the charge converted by the first photoelectric conversion unit and a second signal based on the charge converted by the second photoelectric conversion unit, and a second added signal obtained by adding a third signal based on the charge converted by the third photoelectric conversion unit and a fourth signal based on the charge converted by the fourth photoelectric conversion unit.

Claims

[Claim 1] A first photoelectric conversion unit that converts light transmitted through the first microlens into an electric charge, A photoelectric conversion unit that converts light transmitted through the first microlens into an electric charge, comprising a second photoelectric conversion unit disposed next to the first photoelectric conversion unit in a first direction, A third photoelectric conversion unit that converts light transmitted through the second microlens into an electric charge, A photoelectric conversion unit that converts light transmitted through the second microlens into an electric charge, comprising a fourth photoelectric conversion unit positioned next to the third photoelectric conversion unit in a second direction intersecting the first direction, A control unit that outputs a first added signal obtained by adding a first signal based on the charge converted by the first photoelectric conversion unit and a second signal based on the charge converted by the second photoelectric conversion unit, and a second added signal obtained by adding a third signal based on the charge converted by the third photoelectric conversion unit and a fourth signal based on the charge converted by the fourth photoelectric conversion unit.
