Electronic circuit and method for enhancing an image

摘要

An electronic circuit 100 and method for enhancing an image, in particular, for use in TV-applications, includes a N-dimensional image enhancement filter 130 for receiving an image signal and at least one further image signal, all image signals representing different pixels of said image. An intermediate signal output from the N-dimensional image enhancement filter 130 is combined with a high-frequency component of the image signal in order to generate an enhanced image output signal. The electronic circuit also includes at least one adjusting element 140 - 1 , 140 - 2 for adjusting the intermediate signal and/or said high-frequency component in response to a determined amount of image enhancement applied to the image signal in the image enhancement filter 130 before being combined.
