Abstract
An image sensing apparatus includes: an image sensing device for sensing light representing a subject image; a first component extractor for extracting a first component having a predetermined frequency out of a photographic image obtained by the image sensing device; a second component extractor for extracting a second component having a frequency higher than the frequency of the first component out of the photographic image; a compressor for compressing a dynamic range of the first component extracted by the first component extractor with a predetermined compression ratio; an image generator for generating an image based on a compressed first component obtained by compressing the dynamic range of the first component by the compressor, and the second component extracted by the second component extractor; and a compression correction coefficient calculator for calculating a compression correction coefficient used in compressing the first component, using the second component extracted by the second component extractor, wherein the compressor determines the compression ratio in such a manner that the larger compression correction coefficient increases the compression ratio based on the compression correction coefficient calculated by the compression correction coefficient calculator, and compresses the dynamic range of the first component based on the determined compression ratio.
