IMAGING DEVICE AND IMAGING SYSTEM

摘要

An imaging device includes pixels including a photoelectric conversion unit, a holding unit that holds charge, and an amplifier unit. The pixels include a first group outputting a signal based on charge generated during a first exposure period, and a second group outputting a signal based on charge generated during a second exposure period longer than the first exposure period. The pixel belonging to the second group includes in the second exposure period a first period during which the charge generated in the photoelectric conversion unit is accumulated in the photoelectric conversion unit, and the charge held by the holding unit is transferred to the amplifier unit, and a second period during which the charge generated during the first period is held in the holding unit, and the charge generated after the first period is held by one of the photoelectric conversion unit and the holding unit.

主权项

1. An imaging device comprising:
a plurality of pixels, each of the plurality of pixels including a photoelectric conversion unit that generates charge by photoelectric conversion, a holding unit that holds charge transferred from the photoelectric conversion unit, and an amplifier unit that outputs a signal based on charge transferred from the holding unit, wherein the plurality of pixels includes
a first group including the pixel that outputs a signal based on charge generated in the photoelectric conversion unit during a first exposure period in each of frames, anda second group including the pixel that outputs a signal based on charge generated in the photoelectric conversion unit during a second exposure period in each of the frames, the second exposure period is longer than the first exposure period, and at least a part of the second exposure period overlaps with the first exposure period, and the pixel belonging to the second group includes in the second exposure period
a first period during which the charge generated in the photoelectric conversion unit is accumulated in the photoelectric conversion unit, and the charge held by the holding unit is transferred to the amplifier unit, anda second period during which the charge generated in the photoelectric conversion unit during the first period is held in the holding unit, and the charge generated in the photoelectric conversion unit after the first period is held by one of the photoelectric conversion unit and the holding unit.
