Member	Description
enable	NR module enable. The options are as follows: HI_FALSE: disabled HI_TRUE: enabled
nr_lsc_enable	LSC gain-referenced NR enable. The LSC gain-referenced NR function can be used when the LSC module is enabled. When the LSC module is disabled, LSC gain-referenced NR does not take effect. The options are as follows: HI_FALSE: disabled HI_TRUE: enabled
bnr_lsc_max_gain	Maximum multiple of reference to the LSC gain Value range: [0x0, 0xBF]
bnr_lsc_cmp_strength	Strength of reference to the LSC gain Value range: [0x0, 0x100]
coring_ratio[HI_ISP_BAYERNR_LUT_LENGTH]	Noise reservation strength, which can be obtained from the coring_ratio array based on the luminance. A larger value indicates that more luminance noise is reserved. A smaller value indicates that less luminance noise is reserved. Value range: [0x0, 0x3FF] #define HI_ISP_BAYERNR_LUT_LENGTH 33
op_type	NR working mode. HI_OP_MODE_AUTO: automatic HI_OP_MODE_MANUAL: manual
auto_attr	Automatic NR attribute
manual_attr	Manual NR attribute
wdr_attr	NR attribute in WDR mode. In WDR mode, the overall NR parameter wdr_attr takes effect.
