JL2008A |
Low-cost Mega Pixel Digital Still Camera Controller |
 General Description |
The JL2008A provides a complete solution for Low-cost Mega Pixel Camera for either toy camera or toy DV. It consists of several camera interfaces such as CMOS sensor, CCIR601 input, CSTN/STN LCD,
SDRAM & DDR SDRAM, Secure Disk (SD) card, and Nand-Gate flash memory. It also combines color processing engine, image compression engine, low-voltage detection, UART transceiver, and USB1.1 interface in single chip, therefore either toy camera or toy DV can easily be built by JL2008A. |
| Features |
| ‧ Four basic operation modes
1) Photo : Supported resolution ranges from VGA, 1.3M, 2.1M, to 3.0M pixels.
2) Video (Movie) : Motion image is unceasingly recording until the memory is full. Following
frame is a typical spec for reference.
→ Simulated VGA: 20 fps@480x368 pixels
→ QVGA: 20 fps@320x240 pixels
3) Voice : PCM format, 8Kbytes/sec
4) Web-cam : USB 1.1
