US 11,115,601 B2 · Image processing apparatus, imaging apparatus, and image processing method

Abstract

An image processing apparatus including a first acquisition unit for acquiring a visible-light image signal representing a visible-ray image which comes into focus at a first distance and an infrared image signal representing an infrared-ray image which comes into focus at a second distance that is shorter than the first distance and an infrared-ray image which comes into focus at a third distance that is longer than the first distance; a second acquisition unit for acquiring first brightness information, hue information, and saturation information from the visible-light image signal and at least second brightness information from the infrared image signal; a third acquisition unit for acquiring third brightness information based on edge information obtained from the first brightness information and edge information obtained from the second brightness information; and a generation unit for generating a second visible-light image using the third brightness information, the hue information, and the saturation information.
