        @veye_xumm 那是否也能把 power_line_frequency 也放進去支援 60hz ? 或是如果是特製版,那能直接把預設做成 60hz 嗎?

          @veye_xumm 另一個想法,如果仿照這作法,camera 收到 USB 0x5514 做 reset (reboot) 可行嗎?

            可以默认支持60hz。回头我们做个定制版本你试试。

                  https://app.mediafire.com/tdaitlbvew6cu

                  v4l2-ctl -d /dev/video0 --set-ctrl=hue=0
                  

                  可以实现重启。

                      这个条纹是稳定不动的吧? 那么就是跟你的60Hz匹配的。
                      这个问题我找了一个资料给你看一下。
                      3f5bae67-bff5-41c5-b2a4-0fe32508e604-image.png
                      现在的问题是,你的灯光强度不仅随交流电变化,而且本身的强度又比较强。
                      这种情况下,如果还是维持曝光时间大于1/120s,那么就可能产生过曝的问题。

                      所以这种现象一定环境下属于没办法解决的正常现象。 你可以换更小的光圈的镜头来解决。

                        @veye_xumm 好的,我再觀察比較ㄧ下不同環境跟不同攝像頭看看。
