Dear David-san
y_target modification worked well.
And I modified the agc.cpp as attached, but I see compile error.
Message says RPI_LOGGING_ENABLE is redefined. It is already defined in logging.hpp.
So I modified it.
The log is below.
Thank you very much for your help in advance.
Best Regards,
NOMURA

Subject: Re: [libcamera-devel] How to activate AGC control in libcamera, or set the GAIN/EXPOSURE parameter by v4l2 command.
Hello Nomura-san
Thank you for your message.
It sounds likely that the AGC is running at its maximum values, that is, the exposure time has reached its maximum, and the gain has reached its limit too. Under these conditions changing the y_target will not have any effect.
In normal circumstances I would expect that you could replace the y_target in the json file by (for example)
"y_target":
[
0, 0.32, 1000, 0.33, 10000, 0.34
]
and this would double the exposure (as I have doubled all the target values). However, when the AGC has reached its limits this will not make any difference, and I would guess this is what's happening in your case.
We could confirm this by collecting some debug. I'm intending to do some maintenance on the AGC in the coming days, part of which will replace the debug messages by libcamera debug which can be enabled without recompiling. For the moment, unfortunately, you would have to edit the code (add "#define RPI_LOGGING_ENABLE 1" to the top of
agc.cpp) and recompile. If you were able to capture the last ~50 lines of this debug it would probably clarify the situation for us.
Best regards
David
