      大神:你好
      背景:装备:pi5 和两个imx178漂亮摄像头,
      ./media_setting_rpi5.sh mvcam -fmt RAW8 -x 0 -y 0 -w 1920 -h 1200 -c 0这个代码 运行没问题
      问题 :
      ①我现在想加到12bit(-list-formats里面是Y12P)所以用了这个代码,出现花屏 (修改了宽度和高度也是雪花屏)
      ./media_setting_rpi5.sh mvcam -fmt RAW12 -x 0 -y 0 -w 3088 -h 2064 -c 1

      是不是代码的问题还是相机不支持12bit 灰色的
      ② 以后我的相机是否可以用14bit的(Y14P)的格式

        12bit模式,相机是支持的。但是你现在只可以将其保存为文件,并手动转换为可以方便用软件读取的格式。你可以看一下这个文章part7,尤其是part7.5的部分

        14bit这个,我们现在相机还不支持。sensor是有的,我们没有做这个格式。

          @veye_xumm 大神 谢谢回信
          我们想做的事是灰度的两张图相减,得到测试的结果,所以需要bit数高一点的图, 贵公司有没有那种能达到14bit或者更高的16bit甚至是20bit的相机模块呢(镜头什么牌子都行),有的话 麻烦您介绍一下(我已经查看了贵公司的产品列表,列出来的好像没有)

            你说的对,我们现在还没有那么高的ADC精度的产品。
            你的使用场景,动态范围很宽? 用长短曝光时间来辅助解决可否?

                  @veye_xumm 大神 你好,虽然过了一年了 ,还是念念不忘这个14bit,想请问一下 贵公司要不要继续开发14bit的相机,正好配合sensor的14bit(或者已经开发了的话,请告诉我是哪一款), 然后2x2的一组的 方式抓取数据 ,将来很想买10台或者20台左右。

                    @nian 不好意思,我们暂时没有计划做raw14bit输出的camera模组。
