Abstract
A signal correction circuit for correcting deviating pixel values includes a part (113, 117) for comparing a first pixel value (R.sub.orig) of a given pixel with a second value (R.sub.filt) obtained from pixel values of pixels surrounding the given pixel so as to supply a decision signal (decR) if a predetermined criterion is satisfied; and a multiplexer (115) coupled to the above-noted part (113, 117) for supplying the second value (R.sub.filt) if the predetermined criterion is satisfied for not more than one color (R,G,B), and for supplying the first pixel value (R.sub.orig) in the opposite case.
