Abstract: A restoration filter based on a point spread function of an optical system is applied to source image data acquired through photographing using the optical system to acquire restored image data (S13: filter application step). Adjustment of an amplification factor of the difference between source image data and restored image data is performed, and recovered image data is acquired from the difference after adjustment and source image data (S15: gain adjustment step). In the filter application step, a common filter determined regardless of a value of a magnification of an optical zoom of the optical system is used as the restoration filter, and in the gain adjustment step, the amplification factor is determined based on the magnification of the optical zoom of the optical system.

Abstract: A first restoration processing section 110 and a second restoration processing section 120 perform restoration processing on images (luminance data Y), which are successively captured by an image capture section, using a first filter 102, which is a restoration filter generated corresponding to a point spread function of an optical system, and a second filter 104 of which a restoration strength is weaker than that of the first filter 102. Depending on a result of determination which is input from an in-focus determination section 150 and indicates whether or not the image at the current time point is in a target in-focus state, a selection section 122 selects and outputs either luminance data YA which is processed using the first filter 102 or luminance data YB which is processed using the second filter 104.

Abstract: Source image data is subjected to a logarithmic process (gamma correction process) (S11), and the luminance distribution of source image data is acquired (S12). Then, it is determined whether or not the luminance distribution of source image data corresponds to “a high luminance scene (highlight scene) biased toward a high luminance side” based on a characteristic of a luminance value equal to or greater than a first threshold value in the luminance distribution of source image data (S13). According to the determination result (Y/N of S13), a restoration process based on a point spread function of an optical system is controlled (S14, S15). A restoration filter which is used in the restoration process has a filter coefficient corresponding to image data before the logarithmic process.

Abstract: An image processing unit 36 includes an information acquisition unit 40, a filter acquisition unit 42, and a filter processing unit 44. The information acquisition unit 40 acquires imaging information of original image data which is acquired by capturing an object image using an optical system. In a case in which the imaging information includes the first imaging condition and does not include the second imaging condition, the filter acquisition unit 42 acquires a sharpening filter which is associated with the first imaging condition and is associated with a representative condition of the second imaging condition. The filter processing unit 44 applies the sharpening filter acquired by the filter acquisition unit 42 to the original image data to acquire sharp image data.
