Abstract: An image processing device and an image processing method capable of satisfactorily performing a point image restoration process of a visible light image and a point image restoration process of a near-infrared light image are provided. A point image restoration process is performed on luminance data Y indicating a visible light image and IR data indicating a near-infrared light image using a first point image restoration filter based on a first point spread function with respect to visible light of an optical system and a second point image restoration filter based on a second point spread function with respect to near-infrared light of the optical system. An appropriate point image restoration process is performed on the IR data so that restoration strength (second gain β) in the point image restoration process for the IR data captured with radiation of near-infrared light is higher than restoration strength (first gain α) in the point image restoration process for the luminance data Y.

Abstract: An imaging support device that supports imaging performed by an imaging apparatus includes an acquisition portion that acquires an in-image shift amount between a predetermined position in a captured image obtained by capturing an imaging region by an imaging element and a position of a target subject image showing a target subject, and a focal length of the imaging apparatus, a derivation portion that derives a movement amount required for moving the position of the target subject image to a specific position by a position adjustment portion which adjusts the position of the target subject image in the captured image, based on the in-image shift amount acquired by the acquisition portion, the focal length acquired by the acquisition portion, and information related to a pixel interval of pixels in the imaging element, and an output portion that outputs the movement amount derived by the derivation portion.

Abstract: Image data obtained by imaging of an imaging element capable of imaging a subject with sensitivity to a wavelength band of visible light and a wavelength band of near-infrared light via an optical system is acquired. A point image restoration process using a common restoration filter is performed on the image data of the subject captured with sensitivity to the wavelength band of the visible light by the imaging element and the image data of the subject captured with sensitivity to the wavelength band of the near-infrared light by the imaging element. The common restoration filter is calculated on the basis of average optical characteristics of the optical system obtained by performing weighted averaging of first optical characteristics with respect to the visible light of the optical system and second optical characteristics with respect to the near-infrared light of the optical system.
