      请问设置lut参数可以提高画面的对比度吗?想要提高画面的对比度,需要设置什么参数,在不曝光的情况下,提高画面的对比度?
      若设置lut参数可以提高画面的对比度,可否都提供几个lut 10bitdepth的文件,或告知如何生成相应效果的lut参数文件

        @wackyrabbits 我们现在已经在mv_tools_jetson\i2c_tools\lut_samples目录下提供了几个曲线。
        可以作为参考。

          现阶段使用的gamma1.2_10bitdepth的对比度还是不满足要求的,麻烦再多提供几个lut 10bitdepth 的lut文件

            @wackyrabbits excel表里面可以用这个公式拖拽一下得到符合标准gamma的lut表。
            =MIN(INT(POWER($A1/1023,0.8)*1023),1023)
            但是你如果想任意曲线自定义,建议网上找一下lut生成工具或者自己用程序写一个。

                @wackyrabbits 不客气,如果只是提高亮度,可以简单配置一下aatarget这个参数即可。
