como una potencia matemática de la señal de vídeo entrante, cuyo exponente se denomina gamma.

Escala de grises (Grayscale)

Escala acromática desde el negro hasta el blanco pasando por una serie de grises sucesivamente más claros. La serie de grises se divide en tramos aparentemente equidistantes. Si el convertidor analógico/digital es de 8 bits, el monitor podrá reproducir como máximo 28 = 256 niveles. En un monitor RGB, cada color tiene 256 niveles, de manera que puede reproducir un total de 256x256x256 = 16,7 millones de colores.
