Interfacing video camera

Hi all

I am currently trying to interface a video camera to my Arduino board.

The camera is 4D Systems microCAM Serial JPEG Camera Module - TTL
from http://www.robotshop.com/4d-systems-microcam-serial-jpeg-camera-module-ttl-4.html

The board is an Arduino Mega 2560.

I have no idea where to start, but the eventual idea is that the serial data sent from the Camera should go to the WIFI shield that is being built by my friend and sent over the WIFI network to be displayed on the receiving end of the computer terminal.

So the Arduino doesn't actually have to do anything other than sending it over the wifi connection.

Any help, advice would be greatly appreciated

Application is fourth year engineering project, the quadcopter
expectation was to have flowing video, but I have also come to the realization that this is kind of not possible with just the Mega.

Our idea is to pass along the data as soon as it comes in. But still a bit lost as to how to get started.

If you want to pass on video, why not just use something like a regular video camera and a lightweight 2.4GHz Tx/Rx?

so Richard, can you make any recommendations?
