Claim One:
1. A device for processing pixels in a picture of a video sequence comprising multiple pictures, wherein said device is configured to identify a pixel to be processed in said picture for which a small change or variation in the linear representation of said pixel color results in a comparatively large change or variation in the non-linear representation of said pixel color but the change or variation in the linear representation of said pixel color does not negatively affect visual quality by identifying said pixel for which: with respect to a general color in an area, a variation in a linear representation of a color of said pixel that is smaller than a first threshold value results in a variation in a non-linear representation of said color that is larger than a second threshold value; and said variation in said linear representation of said color results in a variation in a luminance and chrominance based representation of said color that is smaller than a third threshold value; and said device is configured to process said identified pixel by modifying a value of at least one color component of said pixel to reduce variability.
