Abstract:
1. A method for up sampling image data comprising: forming image information for a first image unit, wherein the forming image information for the first image unit includes convoluting in a first direction the image information for a subset of four image units of a plurality of image units with a first set of four coefficients; forming image information for a second image unit, the second image unit being spaced apart in the first direction by less than a whole phase difference from the first image unit with respect to the subset of four image units, wherein the forming the second image unit includes convoluting in the first direction the image information for the subset of four image units with a second set of four coefficients, wherein the first set of four coefficients is different from the second set of four coefficients; wherein the plurality of image units are of a first image resolution and the first image unit and the second image unit are for a second image resolution, wherein the second image resolution is of a higher image resolution than the first image resolution.
