NEDXCM20125GIG UME-0041-0136At Digital Gain=1 and Pixel Correction Mode = Factory White, the relation ofanalog gain and sensitivity is illustrated below:Table 4-4-1 Gain-Sensitivityanalog gain Sensitivity V/(lx・s)1 x1(0dB) 502 x2(6dB) 1003 x4(12dB) 2004 x8(18dB) 4005 x10(20dB) 5006 x12(22dB) 6007 x20(26dB) 1000The digital gain multiplication factor can be calculated as follows:Digital Gain register value: val (0~511), gain multiplication factor: gain (1~2)gain = 2047 / (2047 - val * 2)val = 2047 * (gain - 1)/(gain * 2)Notes:Gain and noise values are proportionally related. Adjust amount of gain inaccordance with the requirements of your camera system.4.5 Setting OffsetThe offset can be adjusted. It is possible to set it in the adjustable range of–60~60(DN) when 10bit is output –15~15(DN) when 8bit is output.Figure 4-5-1 Digital Offset register（the GigEGrab picture）
