Abstract: A photoelectric conversion device includes a plurality of unit pixels each including a charge holding portion to which charges are transferred from four or more photoelectric conversion units. Sensitivity of each photoelectric conversion unit of a first group to incident light is greater than sensitivity of each photoelectric conversion unit of a second group to the incident light. After charge accumulation is started in all the photoelectric conversion units of the second group, charge accumulation is started in the photoelectric conversion units of the first group. After signals corresponding to charges accumulated in all the photoelectric conversion units of the second group are read out, signals corresponding to charges accumulated in the photoelectric conversion units of the first group are read out.

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: An imaging device includes pixels, output lines on each column, an AD conversion unit including column AD conversion circuits connected to the output lines, a first storage unit including holding units connected to the column AD conversion circuits, a transfer unit that transfers signals in the first storage unit, a second storage unit that holds signals from the transfer unit, and an output unit that outputs signals in the second storage unit. The pixels output a first analog signal based on signal from the first photoelectric converter and a second analog signal based on signal from the first and second photoelectric converter. The AD conversion unit converts the first and second analog signals into first and second digital signals. The number of signals corresponding to the first digital signals of signals output by the output unit is less than the number of signals output in parallel from the output lines.

Abstract: An embodiment includes: a pixel unit including first and second imaging regions arranged with effective pixels and first and second reference regions arranged with optical black pixels; and a scanning unit that performs, on a row-by-row basis, reset operations of photoelectric converters and readout operations of pixel signals based on charges generated in the photoelectric converters which includes charge transfer to transfer charges generated in the photoelectric converters to holding portions. The scanning unit drives the pixels in the first imaging region and the first reference region in a first condition where a period from the end of reset operation to the end of charge transfer is a first length and drives the pixels in the second imaging region and the second reference region in a second condition where a period from the end of reset operation to the end of charge transfer is a second length.
