Pixel Response

4.3.1

Linear Response

Gain x1, x2, x4

Gain x1, x2 and x4 are digital amplifications, which means that the digital image data are
multiplied by a factor 1, 2 or 4 respectively, in the camera. Resulting values higher than 255 are
clipped to 255.

Black Level Adjustment

The black level is the average image value at no light intensity. It can be adjusted by the
software by changing the black level offset. Thus, the overall image gets brighter or darker.
