Description

Registers a sensor. This callback API is provided by the ISP library to obtain differentiated initialization parameters and control the sensor.

This API does not support multiple processes.

Prototype

hi_s32 hi_mpi_isp_sensor_reg_callback(hi_vi_pipe vi_pipe, const hi_isp_sns_attr_info *sns_attr_info, const hi_isp_sensor_register *sns_register)

Parameters

Parameter	Input/Output	Description
vi_pipe	Input	VI pipe ID Value range: [0, 12)
sns_attr_info	Input	Attributes of the sensor that is registered with the ISP 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.
sns_register	Input	Pointer to the sensor registration structure
