Abstract
Abstract A method for downscaling an image from a sensor color filter array space having the step of determining an initial image size. The method also has steps of determining a set of stride lengths, locating a single color pixel of interest, and generating a full color pixel. An apparatus having a processor and a memory coupled to the processor for performing the above steps is also disclosed.
