A system and method for reducing an image by receiving a scaling factor which defines a window. Input pixel intensities of the image are summed in real time as they are input and stored until all pixels within the window have been received. The sum is then divided by the number of pixels within the window which produces an average intensity. A pixel having the average intensity is output.

Apparatus and method for efficient implementation of 2-dimensional pixel window averaging

A system and method for selective scaling of an image by selective implementation of a window averaging processing technique or an interpolation processing technique. For enlargement scaling, the interpolation processor is implemented. For reduction scaling, the window averaging processor is implemented. For anamorphic scaling, the window averaging processor may be selected and implemented for reduction processing pursuant to a two-pass processing technique wherein the interpolator processing will be implemented thereafter.
