Scientific background of Ambient Lighting

TV screen is the only source of light in a dark room. Dark and bright scenes are switching very fast when you are watching a movie. Your pupil reacts to the level of light by changing its size, sometimes from 1 to 8 millimeters, and when it is switching from darkness to light, it takes about 5 sec for a pupil to narrow, and up to 5 mins to increase the size of a pupil when it gets darker. That’s why the muscles of an eye are in constant tension which can lead to vision problems. This is exactly why your parents didn’t allow you watching TV in a dark room – they were just trying to protect your eyes.

Ambient Lighting can also level the intensity of light in your room by reducing the difference in lighting between dark and bright scenes or completely eliminating it

How it works

In a nutshell, Lightpack consists of a master board, additional RGB LEDs, firmware that manages hardware and the image capture software called Prismatik installed in Windows, Linux, OS X or even Android. The software figures out an average color of the image displayed on the screen for every capture area corresponded to one LED. After that the color data is transferred by USB to the master board, where the firmware, having handled it, makes the definite LED light by the definite color. This process repeats several dozen times per second.

Lightpack takes an advantage of another feature of human vision: only a very small part of the retina (which is called “macula”) can actually distinguish all the smallest details of a picture, with the picture being fuzzy for the rest of the retina. In fact, the very small (0.2-0.4 mm) part of the macula (called “fovea”) and the farthest from the pupil can recognize the depth of field of a picture. This means that while watching TV you can only see in focus a very small part of the picture on the screen (its size depends on the distance between your eye and the screen). Your brain then works efficiently to combine this small focused part and the rest scene information into a coherent picture. Using the soft illumination of Lightpack which extends the actual picture on the screen, you see your 40-inch TV as if it were a 50-inch home theater.
