Method and system for digital image scaling with sharpness enhancement and transient improvement
An image scaling system includes a single set of line buffers that receive and store input image pixel data in an input video frame. The scaling system also includes a linear two-dimensional sharpness enhancement unit configured to receive input pixel data from the line buffers and to generate sharpened pixel data by enhancing high frequency components of the input pixel data at an input image resolution, a linear two-dimensional image scaling unit configured to receive the sharpened pixel data and to convert the sharpened pixel data into scaled sharpened pixel data at an output image resolution, and a transient improvement unit configured to receive the input pixel data from the line buffers, sharpened pixel data and scaled sharpened pixel data to improve transient responses at edges in an output image, and to generate output image pixel data at the output image resolution.
