Patent attributes
The photoelectric conversion device includes a plurality of pixels, a plurality of signal lines, a pixel control unit that controls readout of signals from the pixels, a column circuit unit that generates pixel data from the signals read out from the pixels, and a signal processing unit configured to perform digital signal processing on the pixel data. The signal lines include first and second signal lines on the same column, and a period of reading out a signal from the first signal line and a period of reading out a signal from the second signal line overlap each other, and the signal processing unit includes a difference acquisition unit that acquires a difference value between a pixel data read out to the first signal line and a pixel data read out to the second signal line, and a correction unit that corrects the pixel data based on the difference value.
