Abstract:
A method for interpolating between a first and second pixel in a video display system, the first pixel having a first pixel value and a first coordinate on a first axis, and the second pixel having a second pixel value and a second coordinate on the first axis, the method comprising:a. providing to data processing resources a first intermediate coordinate in between the first and second coordinates on the first axis; b. determining in the data processing resources, a weight factor for the first intermediate coordinate by inputting the first intermediate coordinate into a first blending function when the first intermediate coordinate is within a first domain, and by inputting the first intermediate coordinate into a second blending function when the first intermediate coordinate is within a second domain, wherein the first blending function and the second blending function are different; and c. calculating in the data processing resources a first interpolated value from a first product of the weight factor for the first intermediate coordinate and a function of the first pixel value and the second pixel value.
