Abstract
A digital image processing apparatus includes first through sixth circuits. The first circuit divides digital input image data into a plurality of blocks, each block defining an area of a predetermined size. The second circuit detects a plurality of features of the divided digital image data for every pixel. The third circuit calculates, for every block, a quantity of each of the detected features supplied from the second circuit. The fourth circuit determines, for every block, the type of area of concern from the calculated quantity of each of the detected features supplied from the third circuit. The fifth circuit processes the digital image data in any one of a plurality of image processing modes, thereby producing output digital image data. The sixth circuit selects the most suitable image processing mode among the plurality of image processing modes on the basis of the determined type of the area supplied from the fourth circuit.
