Members

Member	Description
enable	Dehaze enable. The value can be HI_FALSE (disabled) and HI_TRUE (enabled).
user_lut_enable	User-defined dehazing curve enable
dehaze_lut[HI_ISP_DEHAZE_LUT_SIZE]	User-defined curve parameter. The curve controls the dehazing strength based on the luminance. The curve has a total of 256 points. That is, 256 luminance values are supported. #define HI_ISP_DEHAZE_LUT_SIZE 256
op_type	Dehaze mode HI_OP_MODE_AUTO: automatic HI_OP_MODE_MANUAL: manual
manual_attr	Manual mode. For details, see hi_isp_dehaze_manual_attr.
auto_attr	Automatic mode. For details, see hi_isp_dehaze_auto_attr.
tmprflt_incr_coef	Temporal filtering increment coefficient. A larger value indicates a faster speed of image luminance convergence from dark to bright. Value range: [0x0, 0x80]
tmprflt_decr_coef	Temporal filtering decrement coefficient. A larger value indicates a faster speed of image luminance convergence from bright to dark. Value range: [0x0, 0x80]

Restrictions

The dehazing function takes effect after a two-frame delay to avoid image exceptions.
