<![CDATA[RAW-MIPI-SC53M maximum exposure length]]>Hello, I am looking at the RAW-MIPI-SC53M 5MP camera module, and the documentation states the maximum exposure time is equal to 1/(max fps) which is less than 1 second. However, I would like to take long exposure images (up to 60 seconds exposure) - can this camera do that?

我们相机有一个底层逻辑，fps参数会优先于曝光时间设置。
如果你想要1秒的曝光时间，需要先将帧率设置为1帧/秒，然后再设置曝光时间即可。

曝光时间设置还是有问题，fps一直是30，最大曝光时间一直是33ms，264m。
请看看怎么才能调整长一些曝光时间，比如1s。

可以参考这篇文章进行取图。

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.
