ABSTRACT:
To process pixels included in a video image, control data is generated to established a pixel processing operation for a pixel under consideration. A set of parameter coefficients is generated in response to this control data; and a convolution filter receives successive pixels of an input video image for convoluting the pixel under consideration as well as surrounding pixels with the set of parameter coefficients, thereby producing a processed pixel which is used by further apparatus in place of the pixel under consideration.
