Abstract
A digital image processing device and method for performing edge compensation (sharpening) and emphasis. The digital image processing device and method each employ a first interpolation unit for applying a predetermined interpolation scheme with respect to low-resolution input image information, and outputting first interpolation image information; and a compensation unit for producing binary values with respect to the first interpolation image information using the input image information and the first interpolation image information, and compensating for the first interpolation image information based on the binary values. The device and method also each employ a second interpolation unit for applying a predetermined interpolation scheme with respect to the input image information, and outputting second interpolation image information; and an emphasis unit for emphasizing the compensated first interpolation image information using the second interpolation image information.
