Abstract:
1. An integrated circuit that processes a first set of YCbCr pixel values, the first set comprising a first Y luminance value, a first Cb chrominance value, and a first Cr chrominance value, the integrated circuit generating a second set of YCbCr pixel values, the second set comprising a second Y lumuninance value, a second Cb chrominance value, and a second Cr chrominance value, the integrated circuit comprising: a color phase adjust circuit that receives the first Cb chrominance value and the first Cr chrominance value and that performs color phase rotation based on a relationship between the first Cb chrominance value and the first Cr chrominance value, the color phase adjust circuit outputting an intermediate Cb chrominance value and an intermediate Cr chrominance value; a chrominance adjust circuit that receives the intermediate Cb chrominance value and the intermediate Cr chrominance value and that performs scaling based on the relationship between the first Cb chrominance value and the first Cr chrominance value, the chrominance adjust circuit outputting the second Cb chrominance value and the second Cr chrominance value; a luminance adjust circuit that receives the first Y luminance value and that performs scaling based on the relationship between the first Cb chrominance value and the first Cr chrominance value, the luminance adjust circuit outputting the second Y luminance value; and a circuit that receives the first Cb chrominance value and the first Cr chrominance value and that outputs a number indicative of the relationship between the first Cb chrominance value and the first Cr chrominance value, wherein the circuit supplies the number to the color phase adjust circuit, the chrominance adjust circuit and the luminance adjust circuit.
