(Red, Green, and Blue components of each pixel are treated separately) Each frame is examined as an RGB value and the average value for Red, Green and Blue is calculated. PureAverage - Fastest and least effective. I suggest starting with PureAverage and RuleOfThirds for a good balance of performance vs accuracy.Īll algorithms throw out Grey and Black colors, when these color are considered you mostly get grey for the color of the lights and the dominant color is rarely picked up. These options are saved and the changes start immediately with the next frame processed, so that you can experiment with these in real time and see their impact. The app has a few options to choose from to optimize your experience. To the right of the preview is a preview of the dominant color that the Hue lights will be changed to automatically. Use this preview to align your camera's field of view with as much of the television image as possible. Once the app is running you will see a preview of what the camera is seeing in the app. The app will be registered with the bridge and on future app start ups will connect to the bridge without user intervention. You must then tap the link button on the Hue Bridge and click register in the app. The first time it starts AmbiHueTv will search for Hue bridges and select the first bridge it finds.
When AmbiHueTv runs it will automatically start (the equivalent of clicking the Start button). Note : I recommend doing a Release/Arm build before making this a permanent startup application, this will allow AmbiHueTv to process more frames per second.
#Tv ambient light install
Install the latest Windows 10 IOT for your Pi ( Does this work with other hardware? Let everyone know in the comments section! ).Better configuration for different capture devices.Currently filters for lights with the word "strip" in them and modifies the color on all of them, allow this to be configurable.Currently selects the first Hue Bridge found, this should be configurable.V 1.3 - Bug Fixed that made the colors inaccurate, color change smoothing added. V 1.2 - Added Ability to use Capture Card, see description at end of article. V 1.1 - Added calibration to TV, see description at end of article. After adding some Phillips Hue lights to my home I wanted to see if I could achieve the same effect with extra parts I had laying around the house.įor this project you will need a USB webcam compatible with Windows 10 IoT (see here for compatibility ) or a UVC Capture Card, a Hue Bridge, and a Hue light bulb capable of color changing.
A recent trend in televisions has been the addition of ambient lights behind the screen that is synchronized with the action on the screen.
