Abstract:
A method for reducing bit-depth of image data for an imaging device includes receiving an image frame for display to the imaging device. The method additionally includes applying temporal error diffusion for the image frame to produce a plurality of image subframes, wherein temporal errors generated in one subframe of the image frame are passed to a next subframe of the image frame for temporal error diffusion. The method also includes applying spatial error diffusion to remaining temporal errors from the temporal error diffusion of the image frame.
