Members

Member	Description
fusion_mode	Fusion mode enable HI_FALSE: disabled HI_TRUE: enabled
motion_comp	WDR motion compensation enable The options are as follows: HI_FALSE: disabled HI_TRUE: enabled In some indoor fluorescent light scenarios, motion compensation exacerbates the horizontal stripes caused by frequency flicker. In this case, disable motion compensation.
short_thr	Short exposure threshold. Only short exposure data is selected if the image data is above the threshold. Value range: [0, 0xFFF]
long_thr	Long exposure threshold. Only long exposure data is selected if the image data is below the threshold. Value range: [0, short_threshold]
force_long	Forcible long frame output enable The options are as follows: HI_FALSE: disabled HI_TRUE: enabled
force_long_low_thre shold	Low threshold for forcibly outputting long frames. Long frames are forcibly output in the motion region whose luminance is lower than this threshold. Value range: [0x0, 0xFFF]
force_long_hig_thre shold	High threshold for forcibly outputting long frames. Long frames are not forcibly output in the motion region whose luminance is higher than this threshold.
short_expo_chk	Parameter for determining whether to check the size of short frame data during motion detection. When the short frame data proportion is close to 0, long frames are forcibly selected for WDR fusion. Values: HI_FALSE: The size of short frame data is not checked for WDR fusion. HI_TRUE: The size of short frame data is checked for WDR fusion.
short_check_threshold	Threshold for short frame check. When the luminance of short frames is less than the threshold, long frames in the WDR module are forcibly output. Value range: [0x, 0xFFF]
md_ref_flicker	Whether flicker detection results are referenced during motion detection. The options are as follows: HI_FALSE: no HI_TRUE: yes
md_thr_low_gain	Lower threshold used for judging whether motion occurs in manual mode. A larger value indicates a lower motion degree. Value range: [0, md_thr_hig_gain]
md_thr_hig_gain	Upper threshold used for judging whether motion occurs in manual mode. A larger value indicates a lower motion degree. Value range: [0, 0xFF]
fusion_thr[HI_WDR_MAX_FRAME]	Thresholds of ultra short frames, short frames, medium frames, and long frames in fusion mode. Input data is limited below the threshold. Value range: [0, 0x3FFF] #define HI_WDR_MAX_FRAME 2
mdt_still_thd	Threshold for stillness determination during motion detection. When the motion degree is less than the threshold, the pixel is determined as still. Value range: [0, 0xFE]
mdt_long_blend	Weight of blended long frames in the motion region. When this parameter is set to 0xFE, long frames are selected for all motion regions. Value range: [0x0, 0xFE]
