IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM

摘要

The objective of the present invention is to perform image processing in accordance with differences in the color component and the luminance component of an image, while processing a relatively small amount of data. A frequency resolution unit (110) performs a direct frequency resolution on a Bayer image signal from an imaging element (3). Thus, a high-frequency component indicating color information and a low-frequency component indicating luminance information are obtained. A filter coefficient acquisition unit (131) of a correction processing unit (130) acquires different filter coefficients for the high-frequency component and the low-frequency component. On the basis of the filter coefficients obtained by the filter coefficient acquisition unit (131) a filter processing unit performs different filtering processes on a component image for the high-frequency component and the low-frequency component.
