Brightness of light caught by camera

[Chesshirecat]

I've found TLM's code that reffers to getting current brightness of the screen:

Code: Select all

CurrentBrightness 	:= GetCurrentBrightNess()
GetCurrentBrightNess()
{
For property in ComObjGet( "winmgmts:\\.\root\WMI" ).ExecQuery( "SELECT * FROM WmiMonitorBrightness" )
		currentBrightness := property.CurrentBrightness	
return currentBrightness
}

[Mod edit: [code][/code] tags added.]

Is there something simmilar to get current brightness of light caught by camera ?

Welcome to this AutoHotkey forum!

Just a few thoughts: I don't think it would be similar. The screen brightness is uniform, but a camera has a sensor that might support an individual brightness level for every pixel-- usually millions of them. Accessing such data might also require some special techniques specific to the camera device itself. You might want to search the forum to see whether others have done it.

If You need to get brightness of image from camera, then You can use opencv for such a task
