摘要： A scaler is provided and includes filters each receiving input pixel data and scaling the input pixel data using a scaling factor to generate a scaled pixel value, and a plurality of mixers, less than the plurality of filters. A first mixer performs a first blending operation on a first scaled pixel value and a second scaled pixel value provided by different filters. A second mixer performs a second blending operation on the blended result of the first mixer and a third scaled pixel value provided by anther filter.
