Abstract: A control section sets an exposure timing and an exposure period for imaging pixels for acquiring an imaging picture and light intensity detection pixels for detecting intensity of illumination light individually by an imaging section. A correction gain calculation section calculates a flicker correction gain for each of the imaging pixels on the basis of pixel signals generated by the imaging pixels and pixel signals generated by the light intensity detection pixels.
