Abstract
An image processing apparatus and an image processing method for amplifying an image signal are provided without reducing an image size and without lowering a sense of resolution. An edge-direction detecting arithmetic section () detects an edge minimum direction from extracted Bayer data (BAY). An assigning arithmetic section () assigns a coefficient in which weighting is applied in the edge minimum direction of the extracted Bayer data (BAY) at a higher distribution ratio than other directions to a spatial filter kernel. In other words, the coefficient of the spatial filter kernel is changed in accordance with the edge minimum direction. A pixel adding arithmetic section () performs a sensitization process of extracted Bayer data (BAY). Therefore, it becomes possible to selectively perform a low-pass filtering process in the edge minimum direction. As a result, a sense of resolution can be prevented from being lost during the low-pass filtering process, and the sharpness of the outline of an image can be maintained.
