Patent attributes
An imaging device includes pixels each including first and second photoelectric conversion units on which pupil-divided parts of incident light are incident and a holding unit that holds charges transferred from the first and second photoelectric conversion units, and outputting signals based on amounts of charges held by the holding unit. Each pixel outputs a first signal and a second signal based on amounts of charges generated by the first photoelectric conversion unit and by the first and second photoelectric conversion units, respectively, during a first exposure time, and a third signal and a fourth signal based on amounts of charges generated by the first photoelectric conversion unit and by the first and second photoelectric conversion units, respectively, during a second exposure time. The first and second signals are output before the third and fourth signals in one frame and after the third and fourth signals in another frame.
