Abstract
This paper presents the design of a novel compression method for wireless image sensor node. In order to meet the requirement of the wireless image sensor node, a dedicated filtering procedure is developed for raw Bayer CFA pattern. JPEG-LS encoder follows the filtering procedure to compress the data. The parallel and pipeline structure are chosen for the purpose of high throughput and real-time operation. The compression method is implemented using UMC 0.18 mum technology. The test results shown that the image with VGA (640times480) resolution and frame rate 15 fps can be achieved with the same clock frequency with the CMOS image sensor.
