Abstract
In some cases, conventional digital zoom techniques can lead to poor quality images. Disclosed are systems and methods for improving the quality of images generated by digital zoom. For example, in some embodiments, a parallel structure is utilized where an image is passed through a sharpener and a 2D directional upscaler at the same time. Upscaling operations are then performed on the sharpened image. The upscaled sharpened image is added to the output of the 2D directional upscaler to produce an enhanced image.
