@izaak In fact, in the Video streaming mode, it is impossible to achieve an exposure time of 1 second. I conducted a test in the 2 - lane raw8 format, as follows:

pi@raspberrypi:~/mvcamera/mv_tools_rpi $ ./mv_mipi_i2c_new.sh -w fps 0.01 w fps 0.01 pi@raspberrypi:~/mvcamera/mv_tools_rpi $ ./mv_mipi_i2c_new.sh -r fps r fps is 3.48 fps pi@raspberrypi:~/mvcamera/mv_tools_rpi $ ./mv_mipi_i2c_new.sh -w metime 1000000 w manual exp time is 1000000 us pi@raspberrypi:~/mvcamera/mv_tools_rpi $ ./mv_mipi_i2c_new.sh -r exptime r current exptime is 287129 us

It can be achieved in Pulse Trigger Mode. However, due to the excessive accumulated dark current, the signal noise will be very high. I don't think it has practical value.
