JL2005A is a low-cost chipset for dual-mode Toy Camera. It consists of required camera interfaces such as CMOS sensor, SDRAM, I2C interface, and USB 1.1 in order to construct a low-cost Toy Camera. Functionally,
JL2005A 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, or configured as motion image to PC
through USB 1.1 interface. This USB 1.1 interface can also provide the basic video conference function in
network through PC. |
