(57) [Problem] To reduce image quality deterioration due to loss of high frequency components of a compressed image due to high compression ratio even when a plurality of compression ratios can be selectively set. A control unit for centrally controlling an imaging operation of a digital camera includes a filter unit for performing a filtering process (contour enhancement process) of image data and a recorded image generating unit for performing a compression process. In the digital camera, two types of compression ratios can be set by the switch S COMP , and the filter unit 211f has a digital filter having a plurality of filter characteristics corresponding to the compression ratios. The control unit 211 performs a filtering process on the image data with a filter characteristic corresponding to the set compression ratio, and compresses the image data at the compression ratio to generate a recorded image (compressed image). Record on the card 18. By changing the filter characteristics according to the compression ratio, image quality deterioration due to compression processing is reduced. |
