Abstract:
1. A color interpolation apparatus for interpolating a luminance signal or a chrominance signal from a Cyan, Magenta, Yellow, Green (CMYG) color signal output from a photoelectric device, the color interpolation apparatus comprising: an area determination unit which determines an area between a flat area and an edge area, to which a sampling unit formed with two pixels of the photoelectric device, vertically adjacent to each other, and to be interpolated belongs; a linear interpolation unit which performs linear interpolation of the sampling unit that is determined to belong to the flat area in the area determination unit, and outputs the luminance signal or the chrominance signal; a weight value calculation unit which provides the weight value of an adjacent sampling unit to be used for weight interpolation of the sampling unit that is determined to belong to an edge area in the area determination unit; and a weight interpolation unit which performs weight interpolation of the sampling unit determined to belong to an edge area, based on the weight and outputs the luminance signal or the chrominance signal.
