hi_mpi_isp_set_iris_attr

Description

Sets iris control attributes. This function can be used to set parameters such as manual iris attributes and iris types.

Prototype

hi_s32 hi_mpi_isp_set_iris_attr(hi_vi_pipe vi_pipe, const hi_isp_iris_attr *iris_attr)

Constraints

• You are advised to set the iris type attribute based on the iris type of the actual connected lens, and then set the corresponding control attribute of the DC-Iris or P-Iris. If the connected lens uses the manual iris, the iris type can be set to HI_ISP_IRIS_DC_TYPE, and you are advised to disable AI in this case.
• The manual iris attribute is used for debugging, and can be configured by using this MPI. For the P-Iris, the manual iris parameter iris_fno is affected by the maximum and minimum iris target values. Parameters related to the automatic iris attribute can be configured by calling hi_mpi_isp_set_dciris_attr and hi_mpi_isp_get_piris_attr.

Parameters

Returns

• 0: success
