RAW-MIPI-SC53M maximum exposure length
-
@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 usIt 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.

@veye_xumm 这种情况下如何采集图像,使用mv_mipi_i2c_new.sh可以设置曝光时间,但是如何采集,没有demo。
-
@golden0514 你的嵌入式平台是什么?
-
@veye_xumm 树莓派4b

@veye_xumm 按照这篇文章里修改曝光时间没有效果,设置成1或者255,采集的图像几乎不变。
-
@golden0514 这篇文章没有修改曝光时间的东西吧? 有设置格式,分辨率,帧率,取图相关的内容。
-
@veye_xumm 刚才试过了,问题解决,最大曝光时间0.3″,基本够用了
-
@golden0514 你可以进一步将fps设置小,相应的最大曝光时间也会拉长。
-
@veye_xumm

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。 -
@golden0514 你好。
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。
