Function Description

Deregisters a sensor. This callback API is provided by the ISP library. This API does not support multiple processes.

Prototype

hi_s32 hi_mpi_isp_sensor_unreg_callback(hi_vi_pipe vi_pipe, hi_sensor_id sensor_id)

Parameters

Parameter	Input/Output	Description
vi_pipe	Input	VI pipe ID. Value range: [0, 12)
sensor_id	Input	ID of the sensor that is registered with the ISP library. sensor_id can be configured in the sensor library and must be unique. It is used to ensure that the sensor deregistered from the ISP library is the same as that deregistered from the 3A algorithm library.

Parameter
