| 1. A digital image processing apparatus comprising:
a charge coupled device (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 into a predetermined unit; and
an adaptive dual slope estimation (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.
