Patent ID: 7620243

Claim:
A method for reducing the perceived noise associated with a replication of an input color stored in memory comprising: adjusting the input color toward a primary tone at the expense of replicating the input color stored in memory according to its proper hue comprising the steps of: computing a luminance value and hue-saturation components of the input color by projecting the input color components along a set of vectors; deriving a hue angle from the hue-saturation components of the input color; using the hue angle to associate the input color with a closest primary tone; calculating the hue-saturation components of the output color as the sum of the hue-saturation components of the closest primary tone multiplied by a first weighted factor multiplied by a second weighted factor, wherein the first weighted factor is related to the hue angle and the luminance value of the input color; and combining the luminance value with the hue-saturation components of the output color according to the set of vectors to obtain the color components of the output color; and displaying an output color wherein the output color is the adjusted input color stored in memory.
