VGA Digital Camera Controller
General Description
JL2005C is a low cost and highly integrated DSC controller. It consists of CMOS image sensor interface, image processing, image compression engine, low battery detect, status LCD interface, DDR/SDRAM interface, UART port and USB1.1 interface. JL2005C supports most popular VGA sensors. It provides dual-mode operation, DSC mode and PC CAM mode. It is designed to fulfill the requirements of digital camera applications.
The JL2005C integrates excellent image processing features such as AE, bad-pixel cancellation, image compression engine. In DSC mode, it stores the compressed image data to an external SDRAM. In PC-Camera mode, the compressed image data is downloaded to PC though USB interface.
