The LM9704 contains all functions needed to build an SXGA or VGA digital still and video camera. It incorporates a 16 bit RISC microprocessor, a flexible image processing pipeline, hardware JPEG compression, and the required peripheral 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 LM9704 keeps the memory cost of the complete camera to a minimum. A chip set comprising of the LM9704 and a National SXGA or 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.
