Abstract: An imaging device includes first and second pixel cells. The first and second pixel cells each include: a photoelectric converter that generates charge; a first charge transfer channel that has a first end electrically connected to the photoelectric converter, and a second end, the charge transfer channel transferring the charge in a direction from the first end toward the second end; a second charge transfer channel that branches from a position of the charge transfer channel, the second charge transfer channel transferring at least a part of the charge; and a charge accumulator that accumulates charge transferred via the second charge transfer channel. Distances from the first end to the position in the direction of the first and second pixel cells are different from each other.

Abstract: A solid-state imaging device that suppresses streaking includes an imaging region in which unit cells are aligned in matrix, an A/D converter for converting an analog signal generated in the imaging region to a digital signal, and a ramp buffer having an input terminal and an output terminal. Ramp voltage is input to the input terminal, and a reference signal having the ramp voltage is output from the output terminal toward the A/D converter. The A/D converter includes a comparator disposed in each column for comparing an analog signal with a reference signal, and a counter disposed corresponding to the comparator for counting a comparison period of the comparator. The ramp buffer includes a feedback circuit for simultaneously outputting the reference signal to the multiple comparators and controlling the amount of current flowing to the output terminal according to the ramp voltage of the reference signal output from the terminal.

Abstract: In an imaging device, a first digital signal corresponding to a first analog signal read out from a pixel, and a second digital signal corresponding to the amount of charge accumulated during a first exposure period following a period for reading the first analog signal. A difference is acquired between a first difference and a second difference wherein the first difference is a difference between a third digital signal and the second digital signal, the third digital signal is a digital signal corresponding to the amount of charge cumulatively accumulated during the first exposure period and a following second exposure period, and the second difference is a difference between the second digital signal and the first digital signal. At least one of the first exposure period or the second exposure period includes a period during which the first light source is in the on-state.
