Abstract:
1. A scaler comprising: a plurality of 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, wherein a first mixer among the plurality of mixers performs a first blending operation comprising multiplying a first scaled pixel value provided by a first filter among the plurality of filters and a second scaled pixel value provided by a second filter among the plurality of filters by a first blending coefficient to generate a first blended result value, and a second mixer among the plurality of mixers performs a second blending operation comprising multiplying the first blended result value provided by the first mixer and a third scaled pixel value provided by a third filter among the plurality of filters by a second blending coefficient to generate a second blended result value, the second blended result value being output by the scaler as output pixel data corresponding to the input pixel data.
