| Abstract | PROBLEM TO BE SOLVED: To solve the problem in which performing color interpolation using mixing reduces the sharpness of an edge.SOLUTION: A color interpolation method uses a first interpolation function (F1) to obtain a first missing color sub-pixel value for a pixel to be an object of color interpolation, and uses a second interpolation function (F2) to obtain a second missing color sub-pixel value for the pixel to be the object of the color interpolation. A first metric (V) indicative of an edge extending in a first direction (D1) is obtained. A second metric (H) indicative of an edge extending in a second direction (D2) is obtained. The two metrics are used to generate first and second weighting factors (k1, k2). A confidence factor value can be used to place more emphasis on one metric compared to the other metric in the determination of the plurality of weighting factors. |
