Abstract: An image capturing device includes an image capturing section that captures first video data having a frame cycle of a first frame cycle and an exposure time for one frame shorter than the first frame cycle, an image acquisition section that acquires the first video data captured by the image capturing section, a detection section that detects a flicker of a light source in the first video data, and an image capturing frame cycle control section that controls the frame cycle of the image capturing in the image capturing section. The image capturing frame cycle control section changes the frame cycle of the first video data captured by the image capturing section from the first frame cycle to a second frame cycle, which is a frame cycle shorter than the first frame cycle, in a case where the detection section detects the flicker.

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: According to the present invention, when restoration processing of a taken image by the use of a restoration filter corresponding to a subject distance is performed, by storing only a corresponding restoration filter in a subject distance range between the estimation variation close range and the infinity such that a restoration filter in a range on the nearer side than the estimation variation close range is not provided from the beginning, it is thereby possible to reduce the number of restoration filters held beforehand.
