UNSOLVED GX-MIPI-IMX662 can't save fps parameter

You need to upgrade your camera firmware. Please refer to the link below to download the firmware, and then follow the subsequent link for the upgrade procedure.

Hi @veye_xumm, I'm already on the latest version of firmware:
$ ./gx_mipi_i2c.sh -r version -b 4 Read version is C 01.14 and L 01.11Anyway it is not critical issue for me.
I'm trying this new GX-MIPI-IMX662 as improved version of VEYE-MIPI-IMX462 for meteors detection and can't configure with same way.If turn off denoise_strength_3D the video image is very noisy and as in gx_mipi_i2c no feature to read sensor registers, can I ask to you confirm that:
In low light environment ISP enables HCG mode (register FDG_SEL0 0x3030 sets to 0x01) ?Maybe you have other recommendations like for IMX462 in this post :
VEYE-MIPI-IMX462 - manual gain not consistent -

Maybe you have other recommendations like for IMX462 in this post :The issue where the FPS setting cannot be saved is likely because your module is our first version, and the firmware is not fully refined. You can try restoring the factory default settings and then test again.
https://wiki.veye.cc/index.php/Gx_mipi_i2c.sh_user_guide#factoryparamThe GX series and the VEYE series are completely different. If you would like to manually set the exposure time and gain, that is fully supported as well. Please refer to the section about expmode metime mgainin the following link.

I am currently on the Spring Festival holiday. Maybe replay late.

@veye_xumm happy holidays!
Yes, I tried manual and auto gain/expmode and it works as expected.For meteors detection I don't need use denoise3d (or use small value ), as it blurs fast moving objects, but without it the image very noisy, which is probably related to HCG and LCG modes of sensor (as it was for my IMX462M camera and you provided custom firmware with enabled HCG), and it is working perfectly on VEYE IMX462 cameras.
For now it has quality of usual IP camera with same sensor (with denoise3d for night sky), will wait, probably it will be improved in future.
Thank you! -
@alex_ai In the current program, HCG will be automatically enabled when the gain is higher than 26 dB — you can give it a try.
Also, please try turning off the 3D noise reduction.
-
@veye_xumm yes, you are right, I checked image in 25 and 26 dB - and it is switching.
Probably I used high digital gain (because brightness low than from IMX462 in same gain value) and it produces high level of noise.
About denoise, in IMX462 I'm using 0x02, but not sure what is MIDDLE value, because in IMX662 denoise_strength_3D with 128 produces different picture and I decreased to 40 to have something similar
0x02 NR 2D Mode = OFF; NR 3D Mode = MIDDLEWill test couple nights. Thank you.
-
@alex_ai OK, the GX series and the VEYE series use completely different ISP solutions, so their parameters do not correspond one-to-one. I look forward to your test results.
-
@veye_xumm found what was wrong,
high level of noise produced gamma_index = 1 (default value), other looks good. -
@alex_ai Thank you for your feedback; we will look into this issue.
-
@alex_ai I used firmware version 1.14 for comparison and did not observe any significant noise changes in gamma mode 1 compared to other modes. Could you provide your specific usage parameters and environment?
