hi_mpi_isp_awb_lib_reg_callback

Description

Registers the AWB algorithm library.

Constraints

  • The ISP provides unified APIs for initializing, running, controlling, and destroying the AWB algorithm library. If you use the Ascend AWB algorithm library, this API can be ignored. If you use your own AWB algorithm library, you need to call this API to register callback functions with the ISP.
  • This API does not support multiple processes.
  • A maximum of two AWB libraries can be registered.
