Restoration filter generation device and method, image processing device and method, imaging device, program, and recording medium

摘要

The present invention relates to a restoration filter generation device and method, an image processing device and method, an imaging device, a program, and a recording medium. In the restoration filter generation device according to one aspect of the present invention, the information acquisition unit (82) that acquires information indicating variation in color of the optical transfer function of the optical system (14) and the information acquisition unit (82) acquire the information. Based on the obtained information, it is assumed that there is a restoration filter generation unit (84) that generates a restoration filter that weakens the restoration strength according to the variation of the optical transfer function according to the color, and that there is no variation due to the color of the optical transfer function. A restoration filter generation unit (84) for making the restoration strength of the restoration filter weaker than the restoration strength of the determined ideal filter. Thereby, overcorrection is reduced.
