Members

Member	Description
enable	Purple fringing correction enable HI_FALSE: disabled HI_TRUE: enabled
op_mode	Purple fringing correction working mode
var_thr	Value range of var_threshold: [0, 4095].
r_luma_thd	The parameter value is divided into three segments. The value of each segment indicates the R component threshold in the highlight detection module. The value that takes effect depends on the value of the purple_detect_range parameter. A smaller value of purple_detect_range indicates the tendency to the first segment of r_detect_threshold while a larger value of purple_detect_range indicates the tendency to the third segment of r_detect_threshold. Value range: [0, 4095] #define HI_ISP_LCAC_DET_NUM 3
g_luma_thd	The parameter value is divided into three segments. The value of each segment indicates the G component threshold in the highlight detection module. The value that takes effect depends on the value of the purple_detect_range parameter. A smaller value of purple_detect_range indicates the tendency to the first segment of g_detect_threshold while a larger value of purple_detect_range indicates the tendency to the third segment of g_detect_threshold. Value range: [0, 4095]
b_luma_thd	The parameter value is divided into three segments. The value of each segment indicates the B component threshold in the highlight detection module. The value that takes effect depends on the value of the purple_detect_range parameter. A smaller value of purple_detect_range indicates the tendency to the first segment of b_detect_threshold while a larger value of purple_detect_range indicates the tendency to the third segment of b_detect_threshold. Value range: [0, 4095]
y_luma_thd	The parameter value is divided into three segments. The value of each segment indicates the luminance component threshold in the highlight detection module. The value that takes effect depends on the value of the purple_detect_range parameter. A smaller value of purple_detect_range indicates the tendency to the first segment of luma_detect_threshold while a larger value of purple_detect_range indicates the tendency to the third segment of luma_detect_threshold. Value range: [0, 4095]
cbcr_ratio	The parameter value is divided into three segments. The value of each segment indicates the blue degree of the purple detection module. The value that takes effect depends on the value of the purple_detect_range parameter. A smaller value of purple_detect_range indicates the tendency to the first segment of cb_cr_ratio while a larger value of purple_detect_range indicates the tendency to the third segment of cb_cr_ratio. Value range: [-2048, 2047]
purple_det_range	Purple detection range. This value controls whether the r_detect_threshold, g_detect_threshold, b_detect_threshold, Iuma_detect_threshold, and cb_cr_ratio parameters take effect. A larger value indicates that purple in more non-highlighted regions are defined as purple regions. purple_detect_range may cause unsmooth purple fringing reduction. You can check the settings of r_detect_threshold, g_detect_threshold, b_detect_threshold, Iuma_detect_threshold, and cb_cr_ratio. Value range: [0, 410]
manual_attr	Purple fringing correction strength parameter in manual mode.
auto_attr	Purple fringing correction strength parameter in automatic mode.
