      色度是指這個嗎?我可以試看看
      hue 0x00980903 (int) : min=0 max=100 step=1 default=50 value=50
      我用 v4l2-ctl 下
      v4l2-ctl -d /dev/video0 --set-ctrl=hue=0
      可是它還是顯示 value=50

        @coolmitch 我用另一個別的廠牌的 uvc camera 可以這樣設定。

          我的意思是,冒用这个协议。 这个需要单独给你做一个版本的固件升级包,现在的版本当然是不支持了。

            @veye_xumm 我的意思是,就目前的版本,我也無法去設定他的值(但在其他的攝像頭可以設定)。所以是否改的冒用的版本也不能用?

                @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。

                        @coolmitch 现在默认值就是60hz.

                          https://app.mediafire.com/tdaitlbvew6cu

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

                          可以实现重启。

                            @veye_xumm 可以重啟。但我在日光燈下還是有條紋。x_2.jpg

                              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。
