All Pixelink cameras.
Gamma controls the contrast in the image and is typically used in microscopy to improve the perceived dynamic range. The linear output of the camera is modified by translating pixel values according to a logarithmic curve. Gamma with a value of one is a linear translation and is perceived as having too much contrast. For images viewed on a LCD monitor, a gamma of 2.2 improves the image contrast.
High or low values of gamma will result in missing codes in the image histogram.
The Gamma curve is applied internally in the camera in the form of a calculated look up table – the same table used by the Look Up Table feature. When the Gamma feature is activated, the Look Up Table feature is disabled and vice versa.
