摘要： An imaging device includes a pixel cell including: a first photoelectric converter that generates a first electrical signal; and a first signal detection circuit that detects the first electrical signal. The first signal detection circuit includes: a first transistor one of a source and a drain of which is electrically connected to the first photoelectric converter; a first capacitor having first and second ends, the first end being electrically connected to the other of the source and the drain of the first transistor, a reference voltage being applied to the second end; and a second transistor having a gate electrically connected to the first photoelectric converter. The pixel cell outputs, in one frame period, a first image signal and a second image signal in sequence, the first image signal being output when the first transistor is off, the second image signal being output when the first transistor is on.

摘要： 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.

摘要： An imaging device includes a semiconductor substrate including a first surface receiving light from outside, and a second surface opposite to the first surface, a first transistor on the second surface, and a photoelectric converter facing the second surface and receiving light through the semiconductor substrate. The semiconductor substrate is a silicon or silicon compound substrate. The photoelectric converter includes a first electrode electrically connected to the first transistor, a second electrode, and a photoelectric conversion layer located between the first and second electrodes and containing a material absorbing light having a wavelength 1.1 μm or longer. The first electrode is located between the second surface and the photoelectric conversion layer. A spectral sensitivity of the material in a region of 1.0 μm or longer and shorter than 1.1 μm is 0% to 5% of the maximum value of a spectral sensitivity of the material in 1.1 μm or longer.
