Data Type: Sixteen bit word.
USAGE: Units are clock cycles; default value is 0x0100
consecutively. The sensor adjusts the shutter to keep the average and maximum pixel values within normal operating ranges.
The shutter value may vary with every frame. Each time the
shutter changes, it changes by ±1/16 of the current value.
Note:
This graph is obtained by getting multiple
readings over different heights.
