      1. c_demo中都是以IMAGE_ENCODING_I420来取图;SC132作为黑白相机,没有色度数据,是否直接取Y分量就是sensor传上来的原始黑白数据?
      2. 目前能否bypass ISP取到sensor输出的raw呢?PS:D_mipicam.h中IMAGE_ENCODING_BMP和IMAGE_ENCODING_PNG定义有误(最后一个字符漏了空格),编译不过;
      3. 我这边用softtrigger配合D_capture取图时间非常长,200+~300+ ms,比文档给出的45.80ms大太多了,可能是什么原因呢;http://wiki.veye.cc/index.php/Camera_module_Trigger_Mode_manual/zh

        取Y数据得到的不是sensor的原始数据,sensor输出的是raw10bit的数据,经过了isp,主要是gamma,锐化,降噪处理(很凶啊)等。

        1. 目前能否bypass ISP取到sensor输出的raw呢?PS:D_mipicam.h中IMAGE_ENCODING_BMP和IMAGE_ENCODING_PNG定义有误(最后一个字符漏了空格),编译不过;

        现在不支持bypass功能。

        45.8是触发总延迟,还需要叠加曝光时间,然后才能得到数据在物理层输出到平台芯片的时间。

          @veye_xumm 请问硬触发模式下这个延时是不可避免的吗

            @xzh 建议你看一下我们现在的MV系列和RAW系列相机。比如这个;
            https://wiki.veye.cc/index.php/RAW-MIPI-SC132M_Data_Sheet/zh
            这个是raw系列的,没有isp模块,输出y8或者y10,delay和触发延时都很小。

              @veye_xumm 没有isp模块是否意味着这颗sensor的isp需要我自己调,包括gamma、锐化,降噪这些

                @xzh 是的。
                我们机器视觉类的产品分两类,用型号前缀来区分。
                MV系列的带isp模块,但是功能并不是很强,主要有AEC,gamma,lut,坏点校正等。
                RAW系列的则不带isp模块,就是sensor直接输出的数据。
                两个系列共同点就是延迟小,输出RAW数据,适合机器视觉场景。
