Abstract
An image is divided into blocks, and each of the blocks is categorized as a block of interest or a block of non-interest. In signal processing in a camera signal processing unit (), a block of interest is controlled using a parameter given by a main control unit () such that a larger amount of high-frequency components are left than in a block of non-interest. A compression/decompression processing unit () allocates a large amount of codes to a block of interest to effectively suppress a deterioration of image quality in a region of interest. There is provided an image-sensing apparatus which can compress an image into a limited amount of codes such that any deterioration of image quality is unnoticeable.
