Abstract :
In this paper, a still image encoder based on the H.26L intra mode algorithm is proposed and implemented in a FPGA prototype board. H.26L was proposed by ITU-T to provide high compression efficiency for very low bit rate communication. The intra mode in H.26L (H.26Li) uses high level spatial prediction and provides 2 db PSNR gain more than the JPEG standard. It is suitable for still image camera application and can be further extended into video camera application
