Abstract

CCD-RAW data obtained by sensing the image of a subject is applied to a first noise reduction circuit via a offset correction circuit, a gain correction circuit, a linear matrix circuit and a gamma correction circuit. Uncorrelated noise is removed from the CCD-RAW data in the first noise reduction circuit. The CCD-RAW data is subjected to synchronization (color interpolation) in the synchronization processing circuit, and luminance data Y and color difference data C is generated by an RGB-YC conversion circuit. The generated luminance data Y and generated color difference data C is subjected to noise reduction processing on a per-frequency-component basis in the second noise reduction circuit. Suitable noise reduction processing conforming to the state of image data before and after synchronization processing is executed.
