Patent abstract
A detail enhancement system uses a detail filter bank including multiple detail filters covering different frequency ranges. An input video signal representing a digital image is processed in the detail filter, wherein detail signals are extracted by the detail filters at different frequency ranges. Shoot suppression blocks and coring blocks are provided for each detail filter to prevent overshoot/undershoot artifacts and small ringing artifacts, respectively. The overall detail signal is amplitude scaled, and added back to the input signal as an enhancement, to generate a detail enhanced output signal.
