Abstract
A digital image enhancing system for processing pixel contour data comprises a contour filter, means for edge processing and for local noise reduction to reduce the amount of noise in a pixel luminance or color signal (Sin), means to apply a control signal (Ghpf) indicating the gain of a contour signal, and means to apply a control signal (Gcntr) indicating the gain of the contour as a function of local noise in a picture. The means for edge processing and local noise reduction are arranged such that an output signal (Sout) is supplied in response to said input signal (Sin), to a low pass filtered input signal (Slpf) derived therefrom, and to the contour filter output signal (contour) and the above control signals according to the relation:out=cntr*(in−)+if<1, andout=in+(cntr−1)*contour else.
