Note:
This means, the bottom lines of the sensor will be exposured longer! For this reason, this
mode will only make sense, if there is no ambient light and the flash duration is shorter or
equal to the exposure time.
Thus, the gray value factor of the first line, which is similar to the one of the rolling shutter, is
different to the factor of the last line:
ExposureTime2 + FrameTime
GreyValueFactor (last line) = -------------------------
ExposureTime1 + FrameTime
With 80 MHz, for example, the FrameTime is about 194 ms. I.e, doubling from e.g. 1ms to 2ms
won't be visible effectively.
