  • Publication number: 20220086383
    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.

  • Patent number: 11218661
    Abstract: A signal processing apparatus includes an analog-to-digital conversion unit, a determination unit including a comparator, and a data calculation unit that performs calculation. The data calculation unit generates a first calculation result by performing calculation including processing for averaging a first digital signal and a second digital signal or processing for adding the first and second digital signals. The data calculation unit generates a second calculation result based on a difference between the first digital signal and first noise digital data. The data calculation unit switches whether to output the first calculation result or output the second calculation result, based on a comparison result of the comparator.

  • Patent number: 11202023
    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.
