IMAGE PROCESSING DEVICE, IMAGING DEVICE, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM

摘要

The present invention provides: an image processing device which is capable of respectively performing satisfactory point image restoration processing of a visible light image and satisfactory point image restoration processing of a near infrared light image; an imaging device; an image processing method; and an image processing program. In an embodiment of the present invention, a first point-image-restoration filter based on a first point spread function related to visible light in an optical system, and a second point-image-restoration filter based on a second point spread function related to near infrared light in the optical system are respectively used to perform point image restoration processing on luminance data Y indicating a visible light image and IR data indicating a near infrared light image. The restoration intensity (the second gain β) used in the point image restoration processing of IR data imaged as a result of irradiation with near infrared light in particular is set so as to be more intense than the restoration intensity (the first gain α) used in the point image restoration processing of the luminance data Y, to perform appropriate point image restoration processing on the IR data.
