PROBLEM TO BE SOLVED: To accurately correct deviation of a white reset signal from photoelectric conversion characteristics.SOLUTION: A pixel composing an image sensor 200 outputs a WR1 signal and a WR2 signal as two types of white reset signals having different leak periods. A first correction unit 301 calculates slope deviation information in a log area of photoelectric conversion characteristics on the basis of the WR1 signal and the WR2 signal, and corrects deviation of a first white reset signal from the photoelectric conversion characteristics on the basis of the slope deviation information. A second correction unit 302 corrects deviation of a second white reset signal from the photoelectric conversion characteristics on the basis of the slope deviation information. |
