A solid-state imaging device includes: a pixel array unit in which a plurality of pixels are arranged in rows and columns; a plurality of column signal lines which are provided in one-to-one correspondence with pixel columns; a column processor including a plurality of column AD circuits provided in one-to-one correspondence with the plurality of column signal lines; a power supply variation detector which is connected to a power supply wire through which a power supply voltage is transmitted to each of the pixels, and which detects, in correspondence with pixel rows, power supply variation components attributed to variations in the power supply voltage; and a power supply variation corrector which corrects, for each of the pixel rows, a pixel signal detected by the column processor, using the power supply variation components detected by the power supply variation detector.
