Abstract
A data compression method is provided for compressing an image. A coding module may select a plurality of pixels with a sequence order from the image, and compress the plurality of pixels to generate a plurality of compressed pixels. For a current pixel p[i] having a previous pixel p[i−1] and a next pixel p[i+1], the coding module generates a coding mode M[i+1] configured for compressing the p[i+1], and generates a fixed-rate compressed value c[i] corresponding to the p[i]. The coding module stores the c[i] in a compressed pixel, and c[i] encapsulates the coding mode M[i+1]. The coding module then stores the plurality of compressed pixels into a compressed image corresponding to the image.
