Abstract
The present disclosure is directed to memory saving systems and methods for buffer overflow that occurs during image compression. In example embodiments, when an overflow occurs during image compression, the overflow data is written to an allocated designated overflow memory by an overflow handler. This memory can be designed to be rewritten multiple times during the image compression process, and can therefore occupy less memory than would be required in possible alternative solutions that comprise expanding the size of each unit of compression destination memory to account for the worst case compression scenario in each instance. Various embodiments that utilize the designated overflow memory to conserve memory when buffer overflow occurs during image compression are illustrated and described.
