Description

Defines the WB attribute.

Members

Member	Description
bypass	WB bypass enable The options are as follows: HI_FALSE: disabled HI_TRUE: enabled
awb_run_interval	Operating frequency of the WB module. Value range: [0x1, 0xFF]
op_type	Automatic/Manual WB switch. The options are as follows: HI_ISP_OP_TYPE_AUTO: automatic mode HI_ISP_OP_TYPE_MANUAL: manual mode
manual_attr	Manual WB parameter
auto_attr	AWB parameter
alg_type	GW AWB or SpecAWB algorithm. Currently, only HI_ISP_ALG_AWB_GW is supported.

Restrictions

When bypass is HI_TRUE, the configuration of other WB parameters does not take effect and the RGB channel gain coefficient is fixed at 0x100.
The default value of awb_run_interval is 2, indicating that the AWB works once every two frames. You can reduce the AWB running frequency based on service requirements.
