摘要： Provided is an imaging device including a scanning unit configured to control a plurality of pixels so as to perform a shutter scan and a readout scan, and the scanning unit is further configured to switch a drive mode between a first drive mode and a second drive mode having periods of different lengths of the readout scan in control of the plurality of pixels and start the shutter scan performed in the second drive mode before the readout scan performed in the first drive mode ends when switching a drive mode from the first drive mode to the second drive mode.

摘要： 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.

摘要： 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.

摘要： A photoelectric conversion apparatus comprising: pixels; L (L≥3) vertical signal lines disposed on each pixel column; M (M≥2) selection circuits disposed in each pixel, each of the selection circuits respectively connecting one of the pixels to a different vertical signal line; a vertical scanning circuit configured to scan the selection circuits; and a control unit. The control unit sets first operation mode in which the vertical scanning circuit performs a single read scanning operation at a time, and a second operation mode in which the vertical scanning circuit performs multiple read scanning operations at a time. In the first operation mode, the control unit uses first selection circuit out of the M selection circuits for scanning operation. In the second operation mode, the control unit uses a second selection circuit, which is different from the first selection circuit, out of the M selection circuits for scanning operation.
