高通平台ISP调试记录(2)-ASF
asf模块:
negative_thr
值越小 -> 黑边越小
layer_1_gain_positive_lut
layer_1_gain_negative_lut
按照亮度分为64个点, 越大锐化越强
layer_1_gain_contrast_positive_lut
layer_1_gain_contrast_negative_lut
8450平台后亮度区分, 越大锐化越强
layer_1_gain_weight_lut
不是细节, 但是也不是平坦区, 值越大锐化越强
layer_1_clamp_ul
layer_1_clamp_ll
值为0, 约等于关闭asf, 主观上控制黑白边
edge_thr
控制detect edge的大小, 值越大, detect的范围越小, edge越少
layer_1_positive_texture_preserve_factor
layer_1_negtive_texture_preserve_factor
控制还原一下儿positve和negtive的细节
layer_1_sp
radial_activity_adj
值越小, 锐化越弱
radial_gain_adj
值越小, 锐化越弱
