Abstract
An image processing method and device for processing multiple rows of pixels of an image simultaneously with a single instruction. The processing includes selecting a pixel window having a plurality of pixels of an image spanning across multiple rows and columns, building vertical and horizontal load registers to include the plurality of pixels of the selected pixel window, and simultaneously processing selected pixels of the plurality of pixels included in the vertical and horizontal load registers using a single instruction, wherein the vertical and horizontal load registers are shifted when the selected pixels are processed. Accordingly, a method and device for efficient processing of an image is provided.
