Zusammenfassung:This invention is an image pickup device that realizes a wide dynamic range while minimizing circuit area using a pixel array that can pick up a low-sensitivity image and a high-sensitivity image. This invention obtains information (S1/S2) needed for generating a correction coefficient using one more than the number of pixels readout circuits (RC1 to RCn+1). This significantly reduces the circuit area compared with the case of using twice as many readout circuits as pixels for generating the correction coefficient.
