Abstract
A digital image processing apparatus and a method thereof. The apparatus includes a CCD to photoelectrically transform an optical image which is imaged through a lens part, using a mosaic color filter array pattern, a buffer to store a color data output from the CCD by a pixel, in a predetermined unit, and an ADSE logic to color-interpolate a spatially missing color data by adaptively applying a luminance significance element value to a certain color interpolation method, the luminance significance element value indicating contribution of each color to an entire luminance with respect to each pixel color data stored in the buffer.
