Abstract:
A method of interpolating a color sample in a signal having alternately colored samples, the method comprising the steps:providing neighboring color samples of the same color as the color sample to be interpolated; providing a single differently colored sample from the same location as the color sample to be interpolated; and interpolating the color sample to be interpolated in dependence upon the neighboring color samples of the same color and the single differently colored sample from the same location, to furnish an interpolated color sample, wherein said interpolating step comprises the steps: determining a horizontal average of horizontally neighboring color samples of the same color as the color sample to be interpolated; determining a vertical average of vertically neighboring color samples of the same color as the color sample to be interpolated; and furnishing a median of said horizontal average, said vertical average, and said differently colored sample from the same location.
