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
