Member	Description
he_wgt[HI_ISP_AUTO_ISO_NUM]	Blending weight curve of the histogram equalization and source image in automatic mode. You can increase or decrease the luminance based on the luminance of the source image. The curve is in Gaussian distribution, and the horizontal coordinates indicate luminance. #define HI_ISP_AUTO_ISO_NUM 16
blc_ctrl[HI_ISP_AUTO_ISO_NUM]	Strength of automatic control over the gain in dark regions, which is used to suppress noise in dark regions. Value range: [0x0, 0x1FF].
