Abstract
Systems, apparatuses, and methods for generating a blur effect on a source image in a power-efficient manner. Pixels of the source image are averaged as they are read into pixel buffers, and then the source image is further downscaled by a first factor. Then, the downscaled source image is upscaled back to the original size, and then this processed image is composited with a semi-transparent image to create a blurred effect of the source image.
