ST VGXY61 camera sensor driver

==============================



The ST VGXY61 driver implements the following controls:



``V4L2_CID_HDR_SENSOR_MODE``

-------------------------------

    Change the sensor HDR mode. A HDR picture is obtained by merging two captures of the same scene

    using two different exposure periods.



.. flat-table::

    :header-rows:  0

    :stub-columns: 0

    :widths:       1 4



    * - HDR linearize

      - The merger outputs a long exposure capture as long as it is not saturated.

    * - HDR substraction

      - This involves subtracting the short exposure frame from the long exposure frame.

    * - "No HDR"

      - This mode is used for standard dynamic range (SDR) exposures.
