Abstract
Image processing is performed in view of the difference between the chroma component and the brightness component in an image, with a relatively smaller amount of data processed during the image processing. A frequency decomposing unitperforms frequency decomposition directly on Bayer image signals from an imaging element. With this, a high frequency component representing color information and a low frequency component representing brightness information are obtained. A filter coefficient obtaining unitof a correction processing unitobtains filter coefficients and the filter coefficients for the high frequency component are different from those for the low frequency component. A filtering processing unit performs a filtering process on subimages based on the filter coefficients obtained by the filter coefficient obtaining unitin such a manner that processing details of the filtering process for the high frequency component are different from those for the low frequency component.
