Patent ID: 7009662

Claim:
An electronic circuit for enhancing an image by filtering a received image signal, representing an image pixel of said image, the electronic circuit comprising: a high-pass filter for separating a high-frequency component from said image signal; a N-dimensional image enhancement filter for receiving and filtering said image signal under consideration of at least one further image signal representing a neighbor pixel, being located in a N-dimensional environment of said image pixel, in order to generate an intermediate image signal; and a combining element for mathematically combining said intermediate image signal with said high-frequency component of the image signal in order to generate an enhanced image output signal of the electronic circuit, characterized in that said electronic circuit further comprises: means for determining an amount of image enhancement applied to said image pixel by said N-dimensional image enhancement filter; and at least one adjusting element for adjusting said intermediate signal and/or said high-frequency component in response to said determined amount of image enhancement before being provided to said combining element.
