Hello, this is my first post here - I'm a long time user of the Arduino for my quadcopters and am just over the moon about their flexibility and ease of use. I was hoping for some help, I'm not a crazy strong programmer but I do understand some and am learning day by day (I think that's the most fun part!! LOL) 
Here is what I'm trying to do.... I have a live video feed coming from a 1/3 Sony CCD camera like what's used for FPV, and I built an Arduino Mini On Screen Display for it from scratch and found that it's very easy to overlay text and graphics on the video however what I would like to do now is magnify the live video feed... so basically you could be watching the feed on your TV and use a POT or a wheel button and zoom in and out on the image and then move around the zoomed image around on the screen.
Basically, what any digital camera would do on the display screen, you can zoom in and then re-position the image to see different parts. I would also like to be able to change the color of the picture, like applying a color filter so you could tint the video feed yellow or orange or red to help with contrast.
Any ideas?? Or directions... I have searched and searched online and have found different projects but nothing on the magnifying of a live video feed.
Any help or direction would be awesome... thank you so much!!
