Abstract: A restoration process using a restoration filter that is based on a point spread function for an optical system is performed for original image data acquired from an image-capturing element by an image taking of an object image using the optical system, so that recovery image data are acquired. The above restoration process is performed, in a point-image restoration processing section, for color data of the original image data in which a gradation correction has been performed by a logarithmic process. The restoration filter may be configured by a filter coefficient corresponding to the image data before the logarithmic process, or may be configured by a filter coefficient corresponding to the image data after the logarithmic process. Thus, by performing the restoration process capable of flexibly responding to various properties of the original image, it is possible to reduce the image degradation such as the ringing in the recovery image.

Abstract: According to an aspect of the present invention, for which of the original image data before the gradation correction and the original image data after the gradation correction the restoration process is performed is determined depending on whether or not the image information meets the condition under which the ringing appears in the recovery image data due to the restoration process. When the gradation correction is performed after the restoration process, there is a probability that the side effect (the ringing or the like) of the restoration process is emphasized by the gradation correction. Therefore, in the case where the image information meets the condition under which the ringing appears, it is possible to prevent such a side effect (the ringing or the like) of the restoration process from being emphasized by the gradation correction, by performing the restoration process for the original image data after the gradation correction.

Abstract: A color filter array includes a basic array pattern P1 constituted by a square array pattern corresponding to 3×3 pixels. In the color filter array, basic array pattern P1 is arranged in a horizontal direction and a vertical direction repeatedly. G filters that are brightness system pixels are arranged at the four corners and the center, that is, arranged on the both diagonal lines. The G filters are in each line of horizontal, vertical, and diagonal directions of the color filter array, and the color filter array includes a square array that corresponds to 2×2 pixels that are constituted by the G filters. A ratio of the number of G pixels that help most to obtain a brightness signal of the basic array pattern P1 is greater than each ratio of the number of R pixels and the number of B pixels that correspond to the color other than G.
