``V4L2_CID_DETECT_CLASS (class)``
|
|
The Detect class descriptor. Calling
|
|
:ref:`VIDIOC_QUERYCTRL` for this control will
|
|
return a description of this control class.
|
|
|
|
``V4L2_CID_DETECT_MD_MODE (menu)``
|
|
Sets the motion detection mode.

|
|
* - ``V4L2_DETECT_MD_MODE_DISABLED``
|
|
- Disable motion detection.
|
|
* - ``V4L2_DETECT_MD_MODE_GLOBAL``
|
|
- Use a single motion detection threshold.
|
|
* - ``V4L2_DETECT_MD_MODE_THRESHOLD_GRID``
|
|
- The image is divided into a grid, each cell with its own motion
|
|
detection threshold. These thresholds are set through the
|
|
``V4L2_CID_DETECT_MD_THRESHOLD_GRID`` matrix control.
|
|
* - ``V4L2_DETECT_MD_MODE_REGION_GRID``
|
|
- The image is divided into a grid, each cell with its own region
|
|
value that specifies which per-region motion detection thresholds
|
|
should be used. Each region has its own thresholds. How these
|
|
per-region thresholds are set up is driver-specific. The region
|
|
values for the grid are set through the
|
|
``V4L2_CID_DETECT_MD_REGION_GRID`` matrix control.
|
|
|
|
|
|
|
|
``V4L2_CID_DETECT_MD_GLOBAL_THRESHOLD (integer)``
|
|
Sets the global motion detection threshold to be used with the
|
|
``V4L2_DETECT_MD_MODE_GLOBAL`` motion detection mode.
|
|
|
|
``V4L2_CID_DETECT_MD_THRESHOLD_GRID (__u16 matrix)``
|
|
Sets the motion detection thresholds for each cell in the grid. To
|
|
be used with the ``V4L2_DETECT_MD_MODE_THRESHOLD_GRID`` motion
|
|
detection mode. Matrix element (0, 0) represents the cell at the
|
|
top-left of the grid.
|
|
|
|
``V4L2_CID_DETECT_MD_REGION_GRID (__u8 matrix)``
|
|
Sets the motion detection region value for each cell in the grid. To
|
|
be used with the ``V4L2_DETECT_MD_MODE_REGION_GRID`` motion
|
|
detection mode. Matrix element (0, 0) represents the cell at the
|
|
top-left of the grid.
