Abstract
In a noise reduction apparatus or method, at least one of a luminance noise estimate value estimating a luminance noise of a target pixel and a chrominance noise estimate value estimating a chrominance noise of the target pixel is estimated in accordance with an average of luminance signals allocated to a first set of pixels including the target pixel. A noise reduction is performed to a selected one of the luminance noise and the chrominance noise one target pixel by one target pixel based on a corresponding one of a first set of information including the average of luminance signals and the luminance noise estimate value and a second set of information including an average of chrominance signals and the chrominance noise estimate value, the average of chrominance signals being allocated to a second set of pixels including the target pixel.
