1. A method for processing a received signal of an image, said method comprising: deriving information regarding counts of pixels in said image having different luminance values; for each of said luminance values, when said count of pixels exceeds a first value, reducing said count of pixels to said first value and increasing counts of pixels having other luminance values to derive revised counts of said different luminance values; and providing, using a processor, an output pixel of an output image signal based on an input pixel of the image and said revised counts of said different luminance values.
