Abstract: An imaging device includes: pixels arranged in m rows by n columns; a first comparator that generates a first output signal indicating a result of comparison between a first pixel signal outputted from each pixel located in an ath column among the pixels and a reference signal; a first counter that generates a first digital signal by counting a period from start of a first counting period to inversion of the first output signal; and a first control circuit that determines, in accordance with a magnitude correlation between the first digital signal obtained from a first pixel located at the ath column and a bth row and a threshold, a period in which the first clock signal is supplied to the first counter in the first counting period of a second pixel located at the ath column and a cth row different from the bth row.

Abstract: An imaging device includes a plurality of pixels arranged in a matrix, a first signal line connected to the first pixel; a second signal line connected to the second pixel; and a power-supply line connected to at least one of the plurality of pixels. The plurality of pixels includes a first pixel and a second pixel that are located in a same column. Two or more voltages that differ from each other are applied to the power-supply line. When a distance between the power-supply line and the first signal line is denoted by d1, and a distance between the power-supply line and the second signal line is denoted by d2, d1 d2 is satisfied in a second cross-section that is orthogonal to the column direction and that is different from the first cross-section.

Abstract: An imaging device includes a plurality of pixels, a first circuit, a first signal path, and a second signal path. The plurality of pixels includes a first pixel and a second pixel. The first circuit includes a first wiring part and a second wiring part. A signal of the first pixel flows through the first signal path. A signal of the second pixel flows through a second signal path. In a flow of the signal of the first pixel, a first crossing portion is located upstream of a first extension portion. In a flow of the signal of the second pixel, a second crossing portion is located upstream of a second extension portion.
