Abstract

Systems and methods are provided for switching a resolution of an image, wherein the image includes at least one block. In some embodiments, the image is compressed. At least one compressed block in the compressed image is tagged, if the data size of the compressed block exceeds a threshold. A non-transition region is grown based on the at least one compressed block that is tagged until a safe-transition block is reached, wherein the non-transition region includes the at least one compressed block in the compressed image. The resolution of each compressed block in the non-transition region is reduced.
