      Please try close wdr.
      http://wiki.veye.cc/index.php/VEYE-MIPI-290/327_i2c/zh#wdrmode

      Because WDR uses two frames of data at different time points to be merged into one frame.
      If the exposure time is long and the vehicle is fast, there will be problems in your image.You can also try to reduce ghosting by reducing the exposure time without turning off WDR.

        Ok, and which parameter controls exposure in i2c?

        Like on CS?

        ./cs_mipi_i2c.sh -w -f aetime -p1 XXX
        range:(100,1/framerate]

          The parameters of the veye series are not as flexible as those of the cs series, and the parameter you want is mshutter.

            Ok. Have tried mshutter, but shadows presents in all cases.

            If i write mshutter 0x46( 1/1000 ) i expect very short exposure and more dark image. It is ok because we are using light at night.

            But at daylight frame is over exposured. So works only 0x40 (auto shutter). Then at night we have this effect: http://forum.veye.cc/post/185

            Here is only mshutter auto:

                      Here is cmd:
                      sudo ./veye_mipi_i2c.sh -w -f videoformat -p1 PAL
                      sudo ./veye_mipi_i2c.sh -w -f wdrmode -b 7 -p1 0x00
                      sudo ./veye_mipi_i2c.sh -w -f mshutter -b 7 -p1 0x40

                      alt text

                      So it is a daylight. Sensor has auto shutter mode, cars speed is slow because it is parking barrier.

                      Why is double image?

                            OK. So 3D denoise is the key. You can try to have a low level 2d denoise.
