[Jetson Nano Super] IMX519 Camera Poor Image Quality (Severe Color Cast + Blurriness) with Community Tuning File

[Dave-he]

Environment Info

Component	Model/Version
Hardware	Jetson Nano Super 8GB + ArduCAM IMX519 MIPI Camera (SKU: B0261)
JetPack	6.2 (L4T 36.6.0)
Driver	Installed via ArduCAM official script (Arducam-MIPI-Camera/Jetson/JetPack_5.x/)
Tuning File	imx519_camera_overrides.nvtune (community version)
Connection	MIPI-CSI Port 0 (single camera)

Problem Description

After installing the official driver and community tuning file, the IMX519 has two core imaging issues:

1. Severe color cast: Magenta/cyan shift (white objects appear pink, green scenes turn yellow);
2. Blurry images: Text unreadable at 30cm distance, no clear focus point;
3. Additional issues: Noise in low-light (indoor) environments and overexposure in moderate outdoor light.

Reproduction Steps

1. Fresh install of JetPack 6.2, update system;
2. Clone ArduCAM repo, run sudo ./install_driver_imx519.sh to install driver;
3. Reboot, capture photo with nvgstcapture-1.0 --sensor-id=0 -c 1 -o test.jpg → issue occurs 100%.

Troubleshooting Attempted (Rule Out Non-Tuning Issues)

1. Hardware: Cleaned lens, checked CSI cable/pins, tested 2 IMX519 modules → no hardware defects;
2. Software: Manually adjusted AWB/RGB gains, exposure/ISO → color cast slightly improved, blurriness unchanged; Replaced with old tuning files → same issue;
3. Validation: NVArgus debug mode confirms tuning file loaded successfully, override_tuning path in device tree is correct, no error logs.

Request for Help

1. Need optimized IMX519 tuning file for Jetson Nano Super 8GB + JetPack 6.2;
2. If no pre-built file available, please guide:
   • Which parameters in the tuning file to modify (e.g., CCM color matrix, sharpening parameters) to fix color cast/blurriness?
   • How to calibrate white balance/gamma curve for this hardware combination?

Attached Files

• test.jpg: Sample photo (shows color cast and blurriness)
• dmesg.log: Camera initialization log
• nvargus_debug.log: NVArgus debug log

Note: The same IMX519 module works normally on Jetson Orin Nano (JetPack 6.2) with the same tuning file. The issue is presumably due to ISP/driver adaptation on Jetson Nano Super. Thanks for your help—this issue is blocking our project progress!
