Abstract:
A resolution scaler of the present invention uses a shift adder instead of a multiplier for scaling an input resolution. The resolution scaler is provided with a counter controller and a pixel scaler. The counter controller outputs a weight to the pixel scaler. The pixel scaler includes a first shift adder for outputting the first shift value by adding a plurality of first shift arguments generated by shifting the current pixel data, a second shift adder for outputting the second shift value by adding a plurality of second shift arguments generated by shifting the previous pixel data, and an adder for outputting the scaled pixel data by adding the first shift value and the second shift value.
