I recently watched a youtube video where a guy got a camera to recognize when a rubik's cube was held up to it, and it captured the 9 square color combination before snapping a picture of the cube and displaying the 3x3 grid on the screen of his computer. What kind of programming is this and where would I start reading to get into this sort of thing? specifically, controlling a camera, and getting it to pick out certain parts of an image and translate that data.

This comes under the topic "Computer Vision" and OpenCV would be a good entry into this .... http://opencv.org/

maybe have a look at this tutorial :- Cascade Classifier
