    摘要: The invention provides a method and device for interpolating between a first and second pixel in a video display system, where the first pixel has a first pixel value and a first coordinate on a first axis, and the second pixel has a second pixel value and a second coordinate on the first axis. The invention provides a first intermediate coordinate in between the first and second coordinates on the first axis, and determines a weight factor for the first intermediate coordinate. The weight factor is determined by either inputting the first intermediate coordinate into a first blending function if the first intermediate coordinate is within a first domain, or by inputting the first intermediate coordinate into a second blending function if the first intermediate coordinate is within a second domain. Once the weight factor is determined, a first interpolated value is calculated from a first product of the weight factor and a function of the first pixel value and the second pixel value.

Once the weight factor is determined, a first interpolated value is calculated from a first product of the weight factor and a difference between the first pixel value and the second pixel value.
