Description |
|---|---|
chroma_strength |
Chroma NR strength. A larger value indicates greater NR strength. The four channels are separately adjustable. Value range: [0, 0x3] #define HI_ISP_BAYER_CHN_NUM 4 |
fine_strength |
Luminance NR strength. A larger value indicates greater NR strength. Value range: [0x0, 0x80] |
coring_wgt |
Reservation strength of random noise. A larger value indicates that a greater amount of random noise is reserved. Value range: [0x0, 0xC80] |
coarse_strength |
Parameter used for controlling the luminance NR strength. The four channels are separately adjustable. A larger value indicates greater NR strength. Value range: [0x0, 0x360] |
Restrictions
In low-illuminance scenarios, when both coarse_strength and fine_strength are set to the maximum values, edge blurring may occur due to excessive NR strength. It is recommended that these two parameters be set to proper values.
