5.8 Power Frequency group
1. A CMOS sensor captures each row of pixels (from top to bottom) in
sequential order, creating a rolling effect, hence the name "Rolling Shutter".
Instead of being relatively constant. So for example, as the commercial
mains frequency in Europe is 50Hz, fluorescent lights in Europe flicker
at 100 times per second and as the mains frequency in US is 60Hz, so in
the USA they flicker at 120 times per second;
2. This flickering problem is solved by capture row pixels in over the duration of integer number of (n) flicker periods;
3. Select 50HZ will delete the rolling dark band for the 50HZ fluorescent light fluctuation;
4. Select 60HZ will delete the rolling dark band for the 60HZ fluorescent light fluctuation;
