Abstract: The photoelectric conversion device includes a pixel unit configured to output first and second signals from columns of first and second regions, and a processing circuit including a first processing circuit including first and third memories, a second processing circuit including second and fourth memories, and a data exchange circuit. The first memory stores the first and second signals output from the first region, and the second memory stores the first and second signals output from the second region. The data exchange circuit stores the first signals read out from the first and second memories in the third memory, and stores the second signals read out from the first and second memories in the fourth memory. The processing circuit outputs the first signals stored in the third memory from the first processing circuit, and outputs the second signals stored in the fourth memory from the second processing circuit.

Abstract: The photoelectric conversion device includes pixels each including photoelectric converters and a floating diffusion to which charges of the photoelectric converters are transferred, a vertical scanning unit for performing readout processing and reset processing on the pixels while switching the photoelectric converter to be processed and the floating diffusion to be processed, and a control unit that controls the vertical scanning unit. The control unit includes a readout row address generation unit and a reset row address generation unit that generate a row address to be processed. A first cycle in which the photoelectric converter is switched is shorter than a second cycle in which the floating diffusion is switched, an update cycle of the row address is equal to the second cycle, and a setting unit of an update timing of the row address is equal to the length of one cycle of the first cycle.

Abstract: In a photoelectric conversion apparatus, an amplification unit outputs a first amplified signal generated by amplifying a first signal using a first gain, a second amplified signal generated by amplifying the first signal using a second gain, a third amplified signal generated by amplifying a second signal using a third gain, and a fourth amplified signal generated by amplifying the second signal using a fourth gain to an analog to digital (AD) conversion unit in this order. The AD conversion unit generates first to fourth digital signals corresponding to the first to fourth amplified signals, respectively, and outputs the second digital signal and the third digital signal to an output unit prior to the first digital signal and the fourth digital signal.
