Abstract
A low-resolution image having a low resolution and low frequency band is generated from an image sensed by using a single board color image sensor, and pseudo color suppression and color noise suppression are performed on each of the image and low-resolution image. The resolution of the low-resolution image is then restored, and weighted combination is performed on this image and the former image. If it is determined that a pixel of interest belongs to a region where a pseudo color is generated, a MIX ratio calculator () for calculating a ratio coefficient for combination calculates a ratio coefficient by which a color signal of a pixel of the low-resolution image having the restored resolution is the result of the weighted combination. This makes it possible to effectively suppress both a pseudo color and color noise.
