Abstract
A method of generating an upsampled target pixel positioned between two lines of input source data includes the step of comparing pixels of different lines of the source data in a region surrounding the upsampled target pixel to be generated in at least two different directions. An interpolation direction based on the comparison is selected and interpolations between selected pixels of the source data in the determined interpolation direction are carried out to compute intermediate pixels on a line segment passing through the upsampled target pixel. An interpolation between the intermediate pixels is carried out to generate the upsampled target pixel. An apparatus for performing the method is also disclosed.
