Patent ID: 7808558

Claim:
A method of processing an image, comprising: receiving an image chrominance signal F having a transient response; and employing a processor for adaptively enhancing chrominance transient of the signal F based on an adaptive correction signal that is a function of corresponding image characteristics of the transient response of the signal F, to obtain an adaptively enhanced signal G, wherein the corresponding image characteristics comprise local geometric properties of the transient response of the signal F; wherein adaptively enhancing chrominance transient of the signal F further includes: generating an adaptive correction signal AR for enhancing chrominance transient of the chrominance signal F, wherein the adaptive correction signal AR is a function of said corresponding image characteristics comprising local geometric properties of the transient response of the signal F, such that the local geometric properties are characterized by a second derivative of the chrominance transient response of the signal F; and combining the adaptive correction signal AR with the chrominance signal F to obtain said adaptively enhanced signal G.
