Abstract
An image processing apparatus generates an image from a captured image, in which an influence of fine particles in an atmosphere has been reduced. The image processing apparatus acquires the captured image, performs correction processing (i) to correct the captured image to reduce the influence of fine particles in the atmosphere, based on a pixel value of a pixel in which a scattered light component is enhanced due to the fine particles, and (ii) to generate a corrected captured image, and outputs an image based on the corrected captured image. The pixel value of the pixel, in which the scattered light component is enhanced due to the fine particles, is determined based on a lower pixel value, except for a minimum pixel value, within a predetermined block that includes the pixel in the captured image.
