LM9702

LM9702 Real Time Digital Image Processor October 2002 LM9702 Real Time Digital Image Processor General Description The LM9702 contains all functions needed to build a VGA digital still and/or video camera. It incorporates a 16 bit RISC microprocessor, a flexible image processing pipeline, hardware JPEG compression, and the required periphery modules in a single IC. This architecture allows a very fast click-to-click time and full resolution video without sacrificing image quality or cost; because the computation extensive operations are processed by circuitry dedicated to image processing. The highly optimized memory management provided by the LM9702 keeps the memory cost of the complete camera to a minimum. A chip set comprising of the LM9702 and a National VGA CMOS image sensor complemented by a lens, battery, compact flash, power management for the battery, and LCD (optional) yields a complete high performance cost effective digital still and/or video camera.
