Abstract
Systems and methods are provided for image scaling with enhanced compression. One embodiment is a processor that receives an instruction to scale an input image to create an output image that is higher in resolution, and analyzes rows of the input image in sections according to a run length of a predetermined number of consecutive pels. For each run length of consecutive pels, the processor determines a cluster of adjacent pels within the run length having a color intensity value within a threshold range, and determines a replacement intensity value for the cluster based on at least one color intensity value of a pel in the cluster. The processor creates the output image by: upscaling the cluster by the scale factor to multiply a number of pels in the cluster, and changing an intensity value of all pels in the cluster to the replacement intensity value.
