| THine THP7312 ISP driver |
| ======================== |
| |
| The THP7312 driver implements the following driver-specific controls: |
| |
| ``V4L2_CID_THP7312_LOW_LIGHT_COMPENSATION`` |
| Enable/Disable auto-adjustment, based on lighting conditions, of the frame |
| rate when auto-exposure is enabled. |
| |
| ``V4L2_CID_THP7312_AUTO_FOCUS_METHOD`` |
| Set method of auto-focus. Only takes effect when auto-focus is enabled. |

| |
| * - ``0`` |
| - Contrast-based auto-focus |
| * - ``1`` |
| - PDAF |
| * - ``2`` |
| - Hybrid of contrast-based and PDAF |
| |
| Supported values for the control depend on the camera sensor module |
| connected to the THP7312. If the module doesn't have a focus lens actuator, |
| this control will not be exposed by the THP7312 driver. If the module has a |
| controllable focus lens but the sensor doesn't support PDAF, only the |
| contrast-based auto-focus value will be valid. Otherwise all values for the |
| controls will be supported. |
| |
| ``V4L2_CID_THP7312_NOISE_REDUCTION_AUTO`` |
| Enable/Disable auto noise reduction. |
| |
| ``V4L2_CID_THP7312_NOISE_REDUCTION_ABSOLUTE`` |
| Set the noise reduction strength, where 0 is the weakest and 10 is the |
| strongest. |
