using camera to store picture to computer on arduino uno

Hi, I have a camera module and I want to use it to take a single picture using arduino uno and store it in my computer for further processing in the computer. Is there a simple way of doing that?
The camera is NTSC and has a video output wire and audio output wire ( audio doesn't matter for me).

Also I was wondering whether arduino can read from a txt file from computer.
Thanks!

You'll need a camera compatible with the Arduino.

As for the other question, Google would help.

Yes - buy a video digitiser module. Make sure it is NTSC/RS170 compatible, and is supported by your PC's OS.

No but some application on your computer can send the Arduino the text file.
