Abstract
A video processor includes a video filter and a calculation circuit. The video filter performs a low-pass filtering operation on first frame data to obtain brightness distribution data. The calculation circuit obtains difference data between the brightness distribution data and second frame data. The calculation circuit multiplies the difference data and a weighting parameter together to obtain a product, and then summates the product and the second frame data together to generate processed frame data.
