11. THine THP7312 ISP driverΒΆ

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.
