JL2003A is a low-cost chipset for dual-mode Toy Camera. It consists of required camera interfaces such as CMOS sensor, SDRAM, I2C interface, USB 1.1, and TV encoder in order to construct a low-cost Toy Camera
with TV Out. Functionally, JL2003A receives the image raw data from many popular CMOS sensors, and then store it into SDRAM. All the captured image/photo stored in SDRAM can be uploaded to PC, configured as
motion image to PC, or converted to CCIR signal for TV display. Its USB 1.1 interface can provide the basic video conference function in network through PC. |
