Member	Description
strength[HI_ISP_AUTO_ISO_NUM]	DPC strength in automatic mode. The 16 values in this array correspond to the DPC strength under different sensor gains. In general, a larger gain indicates greater DPC strength. For details about the mapping relationship, see Table 1. If two consecutive processing strengths are not the same, the processing strength corresponding to a gain between the two consecutive processing strengths can be determined by using linear interpolation. Value range: [0, 0xFF] #define HI_ISP_AUTO_ISO_NUM 16
blend_ratio[HI_ISP_AUTO_ISO_NUM]	Blending ratio in automatic mode. A larger value indicates a more obvious green cast. If two consecutive blending ratios are not the same, the blending ratio corresponding to a gain between the two consecutive blending ratios can be determined by using linear interpolation. Value range: [0, 0x80]

#define HI_ISP_AUTO_ISO_NUM 	16

blend_ratio[HI_ISP_AUTO_ISO_NUM]

Blending ratio in automatic mode. A larger value indicates a more obvious green cast. If two consecutive blending ratios are not the same, the blending ratio corresponding to a gain between the two consecutive blending ratios can be determined by using linear interpolation.

Value range: [0, 0x80]

Restrictions

The default values in this data structure are stored in sensor_cmos_ex.h. To change the default values, configure the corresponding parameters. If a new sensor is used, you need to refer to the default values of other provided sensors.
The value of a_gain*d_gain*isp_d_gain in WDR mode is the same as that in linear mode.
