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 line of pixels in an image, and the second pixel having a second pixel value and a second coordinate on the line, the method comprising:a. providing to data processing resources a first intermediate coordinate in between the first and second coordinates on the line; 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 if the first intermediate coordinate is within a first domain, and by inputting the first intermediate coordinate into a second blending function if the first intermediate coordinate is within a second domain; 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 difference between the first pixel value and the second pixel value; d. inserting an intermediate pixel having the interpolated value in the first intermediate coordinate on the line between the first and second pixels; and e. outputting a modified line including said intermediate pixel.
