SK-AM62A-LP: 4K/8MP capture with ISP quality issue

Hello Udhayamoorthi,

is that issue because if ISP?

The ISP can process 3280x2464. You can try to save YUV data after ISP:

gst-launch-1.0 v4l2src device=/dev/video3 num-buffers=3 io-mode=dmabuf-import ! video/x-bayer, width=3280, height=2464, framerate=30/1, format=rggb ! tiovxisp sink_0::device=/dev/v4l-subdev2 sensor-name="SENSOR_SONY_IMX219_RPI" dcc-isp-file=/opt/imaging/imx219/linear/dcc_viss.bin sink_0::dcc-2a-file=/opt/imaging/imx219/linear/dcc_2a.bin format-msb=7 ! video/x-raw, width=1920, height=1080, framerate=30/1 ! multifilesink location="imx219-image-%d.yuv"

hello,

Thank you for the pipeline 

1. Using above pipeline how can I view/see the picture using jpeg?

2. Most importantly, video quality also affects when I use isp pipeline.

3. Will it help to increase the quality if I add AWB bin file in our pipeline?

Regards,

You can view .yuv file using pixel viewer - https://github.com/carina-studio/PixelViewer.

The ISP binaries provided in the SDK are not tuned for production level image quality.

No. The AWB configuration is already included in the dcc_viss.bin.

how can i make it production level image qaulity? where exactly i need to work on?

How to add Demosaicing or sharpness here?

Then what’s the procedure to add dcc_2a.bin,dcc_viss.bin for 3280*2464 resolution?

Please take a look at the ISP tuning guide.

i am using dcc_2a.bin file In ISP tunning guid they are mentions before/after color correction but why my capture data/stream is not like after color correction Tuning?

Do i need to add contrast or saturation?

Note: in my image looks like before color correction

i am attching image which i have used the pipeline for capture the data 

gst-lauch-1.0 v4l2src device=/dev/video-rpi-cam0 io-mode=5 num-buffers=1 ! queue leaky=2 ! video/x-bayer, width=3280, height=2464,format=rggb ! tiovxisp sink_0::device=/dev/v4l-rpi-subdev0 sensor-name="SENSOR_SONY_IMX219_RPI" dcc-isp-file=/opt/imaging/imx219/linear/dcc_viss.bin sink_0::dcc-2a-file=/opt/imaging/imx219/linear/dcc_2a.bin format-msb=9 ! jpegenc ! multifilesink location="ti.jpg"

Were you using the dcc_viss.bin and dcc_2a.bin included in the SDK filesystem? Those binaries were tuned for the 1920x1080 resolution. You'll need to retune for 3280x2464 following the tuning guide.
