Abstract
An image comprises pixels, and has repetitive high-frequency information. Decision circuitry identifies the repetitive high-frequency information in at least a subset of the pixels of the image to provide a repetitive-sequence signal. A low-pass filter filters the image to produce low-pass filtered pixels. A switch outputs the pixels of the image as adaptive-filter output, and in response to the repetitive-sequence signal, outputs the low-pass filtered pixels as the adaptive-filter output.
