number of pixel: 628(h)x582(v)<PAL>,

Resolution:380 lines.

scaning frequency:50 Hz

min.lllumination: 0.2~3 Lux

S/N ratio : 40db

white balance : Auto

video output 1.0 Vpp composite 75ohm

power supply:Dc 9v.

my project is "Real time video capture and image processing using fpga".

i plan for edge detection of the input video or brightness control of

    From your camera specs I assume that you have a composite video output camera. So you should best use an FPGA board with a video codec on board. The de2 board (http://de2.terasic.com)is an excellent platform for your project. The board also has worked out examples using such a camera. You should of course update the provided designs for your project.

    The relation of your composite video camera with the (incomplete) block diagram that you have drawn is unclear.

    Please have a look at the de2 (http://de2.terasic.com) reference designs and documentation. It is all in there
