10. THine THP7312 ISP driver¶
The THP7312 driver implements the following driver-specific controls:
V4L2_CID_THP7312_LOW_LIGHT_COMPENSATIONEnable/Disable auto-adjustment, based on lighting conditions, of the frame rate when auto-exposure is enabled.
V4L2_CID_THP7312_AUTO_FOCUS_METHODSet method of auto-focus. Only takes effect when auto-focus is enabled.
0Contrast-based auto-focus
1PDAF
2Hybrid 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_AUTOEnable/Disable auto noise reduction.
V4L2_CID_THP7312_NOISE_REDUCTION_ABSOLUTESet the noise reduction strength, where 0 is the weakest and 10 is the strongest.
