Only the PL-B741 & PL-B681M camera models have brightness controls.


Description


Brightness controls the black level in the image by applying an offset voltage to the pixels before the analog to digital conversion.  A value of zero is the calibrated setting, where a black image should have a histogram peak that is close to zero but not clipped.  Higher or lower values of brightness will shift the peak up or down in the image histogram.
