Does any windows software exist to auto-adjust the brightness of a monitor (laptop screen and external monitor) based on the amount of light that a connected webcam senses?

  • Not sure if such software exists but if its possible its a really good idea, seeing as most modern laptops have built-in webcams. – Connor W Dec 23 '09 at 20:19
  • And the downvote / close is for what? When this question was asked I don't believe the software recommendations stackexached was opened yet. If you feel it is placed here in error please move it there instead of downvoting and voting to close it. – leeand00 Jun 27 '16 at 14:54

I've just done this tonight : http://calvin-studio.fr/projets.php?p=14 (in French)

Archive here , with code + Visual project + executable.

Uses parts of redshift sourcecode, and escapi. So : Windows only, ugly console, never tested on dual display, probably messes with any software calibration tool, f.lux incompatible, Skype/MSN/any_videoconference_software-incompatible.

Works for me, though :)

I ended up with running brightness adjustment every hour (using http://sven.killig.de/BLUntrl/) via the following autohotkey script:

#NoEnv  ; Recommended for performance and compatibility with future AutoHotkey releases.
#Warn  ; Enable warnings to assist with detecting common errors.
SendMode Input  ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir%  ; Ensures a consistent starting directory.

Loop
{
   Run, D:\autohotkey\BLUntrl.exe
     Sleep, 10000
     Send, {Esc}
     Sleep, 3600000
}
Return

This solution seems to work fine with f.lux.

Calvin's application from previous post is great, but it alters color balance on my monitors.

"Many modern laptops include a built-in dedicated light sensor. If yours does, and if you're running Windows 7 Professional or higher, you can enable a Windows feature called "Adaptive Brightness" which will do what you want. Otherwise, click here and download "SoftonEyes"."
