    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: In a case where IR data of a near-infrared light image is data in which a visible light component and a near-infrared light component coexist, a point image restoration process is performed on the IR data using a first point image restoration filter based on a first point spread function for visible light of the optical system and a second point image restoration filter based on a second point spread function for near-infrared light of the optical system. An appropriate point image restoration process is performed on the IR data that is captured in a time zone of twilight or dawn by performing weighted averaging on a point image restoration process using the first point image restoration filter and a point image restoration process using the second point image restoration filter using a first gain α and a second gain β according to a light amount ratio between visible light and near-infrared light at the time of capturing the IR data.

    Abstract: An optical system has the entire angle of view at a wide-angle end of not smaller than 90 degrees. A spatial frequency at which an MTF of the optical system acquired using an evaluation wavelength in a region of an image formation plane in which the distance from the center of the image formation plane is not less than 80% and less than 95% of half of the length of a diagonal line of an imaging surface of an imaging element image is not more than 30% is higher at the wide-angle end than at a telephoto end. When F≥√(Fw×Ft) is satisfied (where F indicates the focal length of the optical system when the target image is captured, Fw indicates the focal length at the wide-angle end, and Ft indicates the focal length at the telephoto end), a sharpening processing unit performs a restoration process based on an optical transfer function of the optical system as a sharpening process.
