Abstract
A system and method for controlling display characteristics is disclosed. The system and method includes a memory and a processor coupled to the memory configured to execute instructions stored in the memory to detect video input from a sensor, receive a control signal from a user and use the input control signal to alter a level of pixel intensity in a video output. The system and method for controlling display characteristics also includes altering the video input into the video output according to an algorithm and displaying the video output signal with an altered level of pixel intensity.
