The iGlasses solution doesn't address the problem as the brightness/contrast adjustments are performed by the hardware (i think) so it will affect the iGlasses input source and thus output. See USAGE.md.ĭoing some work with openCV too and went for the non technical implementation: some tape and black card, and simply covered the light sensor to the left of the camera.
It is also possible to export and import several settings at once, in case you need to reliably and repeatedly configure one or more cameras for various situations. # NOTE: the contrast range for Logitech C920 is 0-255, default value 128. # NOTE: the absolute_exposure_time range for Logitech C920 is 3-2047. # NOTE: the white_balance_temperature range for Logitech C920 is 2000-6500. # Set the white balance temperature to 2000. Uvcc set auto_white_balance_temperature 0 # Export current configuration of the first UVC device found. Here is how to turn off automatic exposure and automatic white balance settings, and manually set white balance and contrast. # Alternatively, skip install and use npx as a prefix to all uvcc commands. Installing the uvcc npm package requires Node.js including npm, or run commands using npx. (Note: I'm the author.) It's a generic tool which should work for any UVC webcams, although I've only tested it with my Logitech C920 HD Pro Webcam. You can find the uvcc source code on github. Try uvcc, a tool to configure USB Video Class (UVC) compliant devices from the command line.
