Image capturing apparatus and method of controlling the same

摘要

An image capturing apparatus comprising an image sensor including a plurality of pixels each including a plurality of photoelectric conversion units, and a first holding unit and a second holding unit configured to store signals output from the plurality of pixels and a driving unit configured to perform first write processing for writing first signals supplied from a first number of photoelectric conversion elements of each pixel in the first holding unit and second write processing for writing second signals supplied from a second number of photoelectric conversion units of each pixel.

主权项

1. An image capturing apparatus comprising:
a plurality of pixels each including a plurality of photoelectric conversion portions; a holding portion which holds signals output from the plurality of pixels; a driver which performs a first holding process for holding first signals supplied from a first number of photoelectric conversion portions of each pixel in the holding portion and a second holding process for holding second signals supplied from a second number of photoelectric conversion portions of each pixel in the holding portion, wherein a period of the first holding process is set shorter than a period of the second holding process, and the second number being larger than the first number; a signal processor which performs a predetermined process on the second signals and generate a captured image data; a memory which stores the captured image data; and a display unit which displays the captured image data, wherein the second signal is used for generating the captured image data in the signal processor, and the first signal and a difference signal between the second signal and the first signal are used for focus detection.
