[Patent application number] 20140125681 [Published] 05-08-2014 [Description] 
METHOD AND APPARATUS FOR ENABLING PARALLEL PROCESSING OF PIXELS IN AN IMAGE - A method, non-transitory computer readable medium, and apparatus for enabling parallel processing of pixels in an image are disclosed. For example, the method performs, via a multiple core processor, a one-dimensional error diffusion on the pixels in the image to reduce a number of bits per pixel to a value lower than an initial number of bits per pixel and greater than one, and performs a two-dimensional error diffusion on the pixels in the image that have undergone the one-dimensional error diffusion, to reduce the number of bits per pixel to one bit per pixel.
