ABSTRACT:
An electronic circuit100and method for enhancing an image, in particular, for use in TV-applications, includes a N-dimensional image enhancement filter130for 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 filter130is 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 element140-1,140-2for 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 filter130before being combined.
