The PM-36 is a fixed-function Codec device that delivers high speed JPEG compression/decompression of color and grayscale image data. An ISO standard for lossy image compression, JPEG can reduce the size of image data without a noticeable difference in image quality. This improves system performance of peripheral-based applications by reducing bandwidth and storage requirements. The PM-36 is ideal for high resolution imaging applications such as copiers, scanners, printers and multifunction peripherals, particularly in networked environments.
