ZR36050PQC-29.5

Product Summary

The ZR36050PQC-29.5 is a high-speed JPEG Image Compression Processor that performs the algorithm specified by the JPEG Baseline and JPEG Lossless standards for high-quality image compression and expansion of continuous-tone color or mono- chrome images. The ZR36050PQC-29.5 performs Discrete Cosine Transform (DCT), quantization and variable-length encoding for image compression (coding), and the corresponding inverse operations for expansion (decoding). The applications of the ZR36050PQC-29.5 include Computer and multimedia add-in boards, Full-motion video compression/expansion, Digital still cameras and peripherals, Security and industrial systems, Videophones and color FAX machines, Color printers and scanners, Fixed bit rate image transmission devices and Cost-sensitive image compression systems.
