Abstract
An image enhancement device is obtained which is capable of extracting, as regions of interest, still objects or objects with smaller motion vectors, or regions located out of the central area of an image. An image processing module (22) applies memorized-color correction to image data, and then stores, in an SDRAM (7) through a memory interface (26), information about the positions of the memorized-color-corrected pixels and information about the application levels (correction levels) applied to the memorized-color-corrected pixels. A mask signal generating module (23) refers to the positional information stored in the SDRAM (7) to extract the memorized-color-corrected regions of the image data as regions of interest. Also, the mask signal generating module (23) refers to the information about the correction levels stored in the SDRAM (7) to set priorities of the regions of interest in such a way that higher priorities are assigned to regions of interest that are memorized-color-corrected at higher levels (i.e., with larger amounts of correction).
