Abstract
An imaging device 100 includes a pixel array PA. A first period, a third period, and a second period appear in this order in a first frame. During the first period, pixel signal readout is performed on a first row in the pixel array PA. During the second period, pixel signal readout is performed on a second row in the pixel array PA. Each of the first period and the second period is a high-sensitivity exposure period. The third period is a low-sensitivity exposure period.
Claims8
An imaging device comprising:
- a photoelectric converter having sensitivity that changes according to a voltage applied to the photoelectric converter;
- and
- voltage supply circuitry that alternately supplies a first voltage and a second voltage to the photoelectric converter, the second voltage being different from the first voltage, wherein
- in a first frame period, a length of a first period from a first point in time at which the first voltage is switched to the second voltage until a second point in time at which the first voltage is switched to the second voltage subsequently to the first point in time differs from a length of a second period from the second point in time until a third point in time at which the first voltage is switched to the second voltage subsequently to the second point in time.
