With measurenoise one can determine how much noise it produces while capturing
frames from a video4linux device. This value can be used with, for example,
- all video4linux compatible devices
Originally this tool used the colorconversion library by smcc but as it is no longer available from that site, I've included it in this release.
0.4 images with high contrast might gave incorrect values, fixed
0.3 optimized for speed, made a couple of parameters configurable
0.2 included the colorconversion library in the tarball
0.1 initial release
Before measuring the noise of the device, you might need to tune and set it up. That can be done with for example the following tools:
Compatible with: all video4linux compatible devices
Can set: tunersettings, brightness, contrast, etc.
Compatible with: Philips-, some Logitech webcams, ...
Can set: framerate, shutterspeed, colorbalance, etc.
Compatible with: Creative, OmniVision, Trust, ...
Can set: band filter, light frequency, etc.
