Abstract
An adaptive color-temperature calibration system and method are disclosed. A chrominance generation unit generates a chrominance criterion according to an input pixel. A matrix generation unit generates a calibration matrix according to the chrominance criterion and a basis matrix. A color calibration unit then performs color-temperature calibration on the input pixel according to the generated calibration matrix, thereby generating an output pixel.
