Abstract
An image processing apparatus processes input signal samples representative of at least part of a color video image to produce legal color signal samples. An over sampled version of the input signal samples is produced. A plurality of adjustment factors are generated which, when combined with the input signal samples, have the effect of converting illegal color pixels of the color image into legal color pixels. The over sampled legalized color signal samples are decimated, resulting in a sampling rate corresponding to that of the base input signal samples, by selecting signal samples from the over sampled version of the legalized color signal samples which have not changed with respect to the corresponding input signal samples. If the signal samples have changed, a plurality of the over sampled legalized color signal samples are combined to produce the decimated legalized signal samples; and if neither the base nor the associated extra color signal samples have changed, base legalized color signal samples are selected.
