      @lin 触发模式下,曝光和图像输出是顺序执行,而不是并行执行。因此,相机配置为120fps,那么每一帧图像输出时间大约是1/120秒。触发信号给到60hz,那么每一帧可以分配到的最大曝光时间大约也是1/120秒。
      换句话说,接收到一个触发信号,1/120秒曝光,1/120秒输出,加起来大约占据1/60秒。完成之后,刚好来得及响应下一个触发信号。
      当然了,我这个说法很粗略,忽略了TTF+TFFV,实际上还需考虑这两个时间的影响。

          先配置lanenum,然后配置fps

              看一下我刚才发的,lanenum和fps都是超链接,点一下。

                好像不能设置成120fps?

                  @lin 这款相机在4lane模式下,才可以支持到120fps。 你需要配置一下lanenum,然后再配置fps。
                  此外,任何时候你都可以通过maxfps指令来读取当前支持的最大帧率。

                    @veye_xumm 我将0x3b的帧率和lanenum进行了修改后,在media-ctl拓扑图中找不到这个相机了,没改过的0x3c还是可以正常找到,什么原因呀?

                      @lin 不好意思,昨天忘了说一个事情。改成4lane之后,用脚本paramsave保存一下参数。
                      然后,需要修改一下dts中的lane的定义——需要改为4lane才可以。
                      此外,需要使用新版本的ADP-MV2,这个板子增加了22pin的那个排线接口。你可以看一下跟你手上的ADP-MV2是不是一样。

                        @veye_xumm 那3588还能同时接两个相机吗?现在是每个相机是2lane的

                          rk3588本身具备同时输入两个4lane的MIPI信号的能力的。关键是你的主板是否引出了对应的接口?

                            只有这一个Mipi接口,2x2lane或者1x4lane,没有别的方法可以提高曝光的时间了吗?除了通过提高lane数,修改相机帧率之外的方法?

                              @lin 你现在用的这个板子,只引出来了2个2lane的mipi接口。无法完成接入两个4lane的相机的工作。你需要换个板子了。

                                @veye_xumm 没有其他方法了吗?只能通过更换成2x4lane的才能提高曝光时间了吗?

                                  @lin 是的。
                                  不过你要是用视频流模式当然可以咯。
