Abstract
A method and apparatus for hardware-base edge handling in video post-processing. In one embodiment, the method includes the identification of at least one unstored input pixel required to compute an output pixel during output pixel computation. Once identified, a pixel value is generated for the at least one unstored input pixel according to a detected edge handling mode. The generation of the pixel value for the unstored input pixel is performed, in one embodiment, if a position of the unstored input pixel is outside a pixel frame boundary. For example, in one embodiment, for output pixel computation of a scaling operation, the frame boundaries include a left (top) edge and a right (bottom) edge for which input pixels required to compute output pixels at or near the frame boundaries do not exist. Other embodiments are described and claimed.
