Abstract
In a case where IR data of a near-infrared light image is data in which a visible light component and a near-infrared light component coexist, a point image restoration process is performed on the IR data using a first point image restoration filter based on a first point spread function for visible light of the optical system and a second point image restoration filter based on a second point spread function for near-infrared light of the optical system. An appropriate point image restoration process is performed on the IR data that is captured in a time zone of twilight or dawn by performing weighted averaging on a point image restoration process using the first point image restoration filter and a point image restoration process using the second point image restoration filter using a first gain α and a second gain β according to a light amount ratio between visible light and near-infrared light at the time of capturing the IR data.
