Part Number: AM62A7
Hi,
I'm trying to tune ISP for my IMX327 camera sensor. While colors, white balancing and exposure seem alright, the image is blurry no matter what values for EE are selected. For the initial dcc configuration I've followed another post on how to use the auto-tune functionality from imaging repository: [FAQ] TDA4VM: How to use Auto-Tune in the python tool under “imaging/tools/” of TDA4x/AM6xA SDK?
I've used 4 different raw frames in different lighting conditions as well as a full black frame for reference. There was no ee dcc file among the freshly generated ones, therefore, I've created it using ISP Tuning tool with default values. Seeing as it hasn't brought any improvements, even thought the ee-mode for gstreamer pipeline was set to MODE_Y8, I used a sample ee dcc file for IMX390 camera sensor. The images received from both captures seem alike (with a slight difference related to the change in ambient lightning).
To my knowledge, the same system but built on the sdk ver. 10 had noticeable improvements on the image sharpeness when run with the ee-mode set to MODE_Y8 (with default ee dcc files).
What could cause this different behaviour between sdk versions, is there a chance that the isp might not read the ee values correctly? DCC binaries build for the system with sdk ver. 10 don't work on the system with a newer version. Are there other ISP components, apart from EE and possibly NSF4, that could influence the sharpness of the images?
UPDATE:
I was confident that ee-mode=1 refers to the EE_MODE_Y8, however, it refers to the EE_MODE_Y12 mode. My camera sensor produces RAW rggb10 frames that should be processed to NV12 format, as far as I understand MODE_Y8 is more appropriate for this scenario. However, when MODE_Y8 is set to the tiovxisp node, it stalls the whole pipeline. MODE_Y12 works just fine, but as described above it doesn't yield any visible improvements. Could you confirm whether my intuition behind MODE_Y8 is correct and if this mode results in the similar behaviour with the other camera sensors?
Best regards,
Konrad
