hi_mpi_ae_sensor_reg_callback
The
The
Description
Registers a sensor. This callback API is provided by the AE algorithm library. The AE obtains differentiated initialization parameters and controls the sensor based on related callback APIs.
Prototype
hi_s32 hi_mpi_ae_sensor_reg_callback(hi_vi_pipe vi_pipe, hi_isp_3a_alg_lib *ae_lib, const hi_isp_sns_attr_info *sns_attr_info, const hi_isp_ae_sensor_register *pregister)
Restrictions
This API does not support multiple processes.
Parameters
Parameter |
Input/Output |
Description |
|---|---|---|
vi_pipe |
Input |
VI pipe ID. Value range: [0, 12) |
ae_lib |
Input |
Pointer to the data structure of the AE algorithm library. |
sns_attr_info |
Input |
Attributes of the sensor that is registered with the AE algorithm library. sensor_id in this structure can be configured in the sensor library and must be unique. It is used to ensure that the sensor registered with the ISP library is the same as that registered with the 3A algorithm library. |
pregister |
Input |
Pointer to the sensor registration structure. |
Returns
- 0: success
- Other values: failure. For details, see ISP System Control Return Codes.
