Abstract
Enhancing the image quality by suitable color noise correction is realized without depending on a subject, a photographing scene, and photographing conditions by determining and correcting a color noise component according to photographing conditions of a camera. The present invention is configured of an imaging device that has: an imaging unit; a signal processing unit that performs signal processing on an image signal inputted from the imaging unit and outputs a luminance signal and a chrominance signal; a camera controlling unit that controls at least one of photographing conditions of optical conditions and exposure of the photographing unit and a signal processing condition of the signal processing unit; and a color noise correction unit that extracts and corrects a color noise component from the chrominance signal inputted from the signal processing unit. The camera control unit controls the color noise correction unit using information of the photographing conditions.
