Multimedia Processor AIT8328 . 1 Overview The AIT8328 is a highly integrated multi-media system-on-chip (SOC) for Sports-cam, Car-cam, and IP-cam devices. The AIT8328 includes dual 32-bit RISC processors, AIT's advanced ISP engine, and high definition MJPEG/H264 video codec up to 1080P30. The powerful on-chip ISP (image signal processor) implements the most advanced algorithm to deliver high-quality image and precision control for AF/AE/AWB. The hardwired WDR engine and rolling-shutter compensation also enhance image/video quality in consumer applications. The video codec supports up to 30 frames per second with 1920x1080 resolution.

5 Pure hardwired architecture achieves low power operation and extends battery time. MCTF (motion -compensated temporal filter) is integrated to enhance image quality and reduce video bit-rate under dark environment. The AIT8328 , powered by Alpha Imaging Technology, will provide complete development environment for customer. Time-to-Market is possible. Applications Sports Camera Car Camera IP Camera 5.
