10    Change the sensor HDR mode. A HDR picture is obtained by merging two
11    captures of the same scene using two different exposure periods.

18    * - HDR linearize
19      - The merger outputs a long exposure capture as long as it is not
20        saturated.
21    * - HDR subtraction
22      - This involves subtracting the short exposure frame from the long
23        exposure frame.
24    * - No HDR
25      - This mode is used for standard dynamic range (SDR) exposures.
