Abstract:
1. A digital camera comprising: an image-capturing device that captures a subject image having passed through a taking lens and outputs image data; a first image processing circuit that first performs pre-treatment on image data corresponding to N lines X M rows output by said image-capturing device in line sequence to create a first image data; a first memory device in which the first image data is temporarily stored; a second image processing circuit that performs format processing appropriate for recording processing on the first image data stored in said first memory device in units of blocks each ranging over n lines X m rows (N>n, M>m, n and m each are equal to or greater than 2) in block sequence, so as to create a second image data having a block size of (n−i) X (m−j), wherein i and j are integers having values of at least 1, in the format processing, the first image data are processed through a plurality of intermediate image processing steps to create the second image data, each of the intermediate image processing steps outputting a block of intermediate image data that is temporarily stored in corresponding memory areas, the block of intermediate image data output from one of the intermediate image processing steps being input to a subsequent one of the intermediate image processing steps to ultimately generate the second image data, a block size of the blocks of intermediate image data output by the intermediate image processing steps becoming smaller sequentially to ultimately obtain the block size of (n−i) X (m−j); and a recording processing circuit that performs recording processing on the second image data, wherein the block size of the (n−i) X (m−j) for the second image data is used for the recording processing.
