The average brightness of the image is calculated. As at V106, the automatic gain control (AGC) is still functioning. The camera tries to correct the image brightness to a standard brightness, then calculates the average brightness. The result is a non linear relationship between actual and the measured brightness. Also, some parts of the image are brighter than others further complicating things. Using a diffuser, e.g. translucent material like a plastic bag, may help. | |||
