Camera controller: This is the brain of Bigshot. Similar to the central processing unit (CPU) of a computer, it follows a set of predefined instructions (called firmware) to control and coordinate all other components of the camera. The controller is fast enough to read (fetch), understand (decode) and follow (execute) millions of simple instructions per second.
