enable	HLC enable HI_FALSE: disabled HI_TRUE: enabled
luma_thr	HLC threshold. If the luminance value is greater than the value of this parameter, the luma_target value takes precedence. Generally, this parameter is set to a large value. Otherwise, many regions of the image are grayed. Value range: [0, 255]
luma_target	Target value of HLC. If the luminance value of a region is greater than the value of luma_thr, the luma_target value takes precedence. That is, the luminance of the region is reduced obviously. Generally, this parameter is set to a small value to reduce the stimulation of the highlight source to human eyes. Value range: [0, 255]

luma_thr

HLC threshold. If the luminance value is greater than the value of this parameter, the luma_target value takes precedence. Generally, this parameter is set to a large value. Otherwise, many regions of the image are grayed.

Value range: [0, 255]

luma_target

Target value of HLC. If the luminance value of a region is greater than the value of luma_thr, the luma_target value takes precedence. That is, the luminance of the region is reduced obviously. Generally, this parameter is set to a small value to reduce the stimulation of the highlight source to human eyes.

Value range: [0, 255]
