Photoelectric conversion device and signal processing device

Abstract

A photoelectric conversion device includes a pixel array, a pixel control unit, and a correction value generation unit. The pixel array includes an effective pixel region outputting a signal according to incident light and a correction signal acquisition region outputting a correction signal for black level correction. The correction signal acquisition region is arranged corresponding to each row of the effective pixel region. The pixel control unit controls pixels of two or more rows in parallel in one row control period, and changes the number of control rows in which the pixels are controlled in parallel in one frame period. The correction value generation unit generates the correction value using a first correction coefficient in a predetermined number of row control periods including a timing at which the number of control rows changes, and generates the correction value using a second correction coefficient in other row control periods.
