ABSTRACT:
Disclosed is a color interpolation method. The present invention decides a precise position of an edge with use of a G value in a unit pixel structure with a size of 3×3, thereby using different color interpolations according to the position of the edge. Also, the present invention provides an effect of emphasizing an edge by emphasizing a brightness and lowering colors when the edge is placed in the vertical center or the horizontal center of the unit pixel structure of 3×3 with use of a property that the edge has stronger brightness than the colors and prevents an incorrect color.
