image processing

we have separate camera module which will going to capture images and store on the COMPUTER .

After that our job is to take those images give it to the board for processing . For that we r using DVI daughter card.

It has TR and RV end. My question is what would be the source through we can send images.

Tell me whether if we could use computer as source for inputing images or else we require other sources such as cd or dvd player
