Tool/software:

Hi team,

We are unable to observe significant changes of LSC tuning. Below are the set of steps that we have followed along with corresponding observations.

1) Using Matlab code: we used the matlab code and steps as suggested in the link: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1405138/faq-tda4vm-how-to-create-lens-shading-correction-lut-for-vpac-viss-lsc?keyMatch=lsc%20lut&tisearch=universal_search

I am also attaching the generated lut txt file (output_LSC_LUT.txt) generated through the matlab code. In this, DCC tool throws an error. Tool generated matlab_log.txt is attached below.

output_LSC_LUT.txt

6840.matlab_log.txt

--->	Error using griddedInterpolant
Interpolation requires at least two sample points in each dimension.

Error in interp1


Error in lsc_calibrate_2 (line 40)

2) Using lens spec file directly in DCC tool: We are able to tune the LSC plugin and generate binary using below generate_dcc.sh shell script. However, we are not able to see any changes. We also tried by changing "lsc_cfg_mode" from 0 to 1 (sensor_lsc_vpac3l_ext.xml) but still there is no impact. PFA the xmls for your reference.

-> We first tried including sensor_lsc_vpac3l_ext.xml only in the generate_dcc.sh but no impact was observed.

-> We also tried including both the xmls (generate_dcc_both.sh uploaded as text file) and still no impact was observed.

Hello Viral,

1) Using Matlab code:

Viral Shah said:
In this, DCC tool throws an error.

Just to clarify, you entered output_LSC_LUT.txt as the LSC Input Table in the DCC tool. Is that right?

Would you mind sharing your lens spec file and the logs of running the Matlab code?

2) Using lens spec file directly in DCC tool:

However, we are not able to see any changes.

Did you try to set the strength to 100% and see if there is any effect?

Hi Viral,

Viral Shah said:
. In this, DCC tool throws an error. Tool generated matlab_log.txt is attached below.

Do you mean you use "output_LSC_LUT.txt" as input to tuning tool LSC plugin and have this error?
That 2D LUT is not the correct input for LSC plugin.

Viral Shah said:
Using lens spec file directly in DCC tool: We are able to tune the LSC plugin and generate binary using below generate_dcc.sh shell script.

This spec file is the expected input for tuning tool.

Viral Shah said:

Do you mean that you see no effect on your camera + EVM?
Could you please share how you tested it on EVM?

Hi Gang and Jianzhong,

1) I am testing the impact of LSC tuning by using a Diffuser. Upon flashing the LSC tuned binary I am not able to see any improvement on the vignetting effect. Below is a comparison of before and after tuned jpg images.

2) I also tried with setting the strength to 100% as suggested by Jianzhong but still am unable to see any impact in captured jpg images i.e. similar observation as above.

3) However, while tuning the plugin, generated output raw image seems to be corrected. Below is a comparison of the same. If I keep the Gamma=70, I am able to see below corrected RAW image. And if I keep Gamma=100, image is same as LSC untuned RAW image. Below are the RAW input vs output images for specified Gamma. I have kept strength = 100%

Gamma = 70:

Gamma = 90:

Gamma = 100:

You should use both XML files:

$DCC_TOOL_PATH/dcc_gen_linux sensor_lsc_dcc.xml
$DCC_TOOL_PATH/dcc_gen_linux sensor_lsc_vpac3l_ext.xml

Upon flashing the LSC tuned binary I am not able to see any improvement on the vignetting effect

Let me investigate this on my side. Please give me a day or two.

Viral Shah said:
If I keep the Gamma=70, I am able to see below corrected RAW image. And if I keep Gamma=100, image is same as LSC untuned RAW image.

Can you share your raw input image, output image of gamma=70, and output image of gamma=100?

Thank you.

Hi Viral,

If you have a linear sensor, you should set Gamma=100.

Gamma<100 is for WDR sensor with more than 16-bit dynamic range.
It will get all pixel values remapped in ISP.

1) I am testing the impact of LSC tuning by using a Diffuser. Upon flashing the LSC tuned binary I am not able to see any improvement on the vignetting effect. Below is a comparison of before and after tuned jpg images.

There seem some artifacts on the top of the right image.

That looks close to a s/w bug we fixed previously on AM62A.

Please check if you have an old version of AM62A SDK which includes that bug.

Hi Gang hua,

1) We are using SDK version 9.1.0. Is there any bug in this version with LSC.

If LSC bugs does exists in the 9.1.0 SDK, Can you provide the patch to fix the same as we are going to use 9.1.0 SDK for long term.

2) We are using AM62A7 SOC, How can we confirm that which VPAC is used at run time.
3) We are trying to do the changes of LSC changes on our custom board. Our custom board is having 1GB RAM. So, when we tried to do LSC changes and tried to flash the tispl.bin, board is giving the below error.

U-Boot SPL 2023.04-gb0d717b732 (Dec 06 2023 - 15:11:45 +0000)

Can you tell us what are the changes required for above error? Do we need to compile the tiboot3.bin as well. If yes, how can we do the same?

Thanks and Regards,

The patch is available in e2e link I shared above (around the end of thread).

AM62A has only VPAC and it is VPAC3L.

What changes are you making?
I don't expect that changing LSC settings would give you any trouble.

Viral Shah said:

None of LSC or VPAC related changes should cause any boot issues.
My friend Jianzhong Xu may have a better idea.

BTW, there might be quite many known issues with 9.1.0 for AM62A (related to VPAC/tiovx/gstreamer).
Therefore, I would prefer moving to a later SDK version if possible.

Jianzhong may have some advice.

How did you rebuild the tispl.bin? What were the changes?

Viral Shah said:

Since 9.1 SDK and 9.2 SDK use the same Linux LTS version 6.1, migrating from 9.1 to 9.2 shouldn't require too much effort. I'd recommend you to use 9.2.

Hi Jianzhong,

I am from Viral's Team.

Jianzhong Xu said:

We have DDR changes. We have used other Part of DDR than EVK which is 1GB in size. So, we are making DDR changes in u-boot source code. Because EVM's u-boot which has 4GB DDR configuration won't work for our board.

After DDR changes in u-boot source tispl.bin, u-boot.img is getting generated but i didn't see tiboot3.bin in the same directory. I am suspecting that authentication is failling between tiboot3 and tispl.

Let us know your thoughts on this. If this is true, than how can we generate the tiboot3.bin. So, there won't be authentication issue.

Note:

Our DDR changes are working fine with yocto SDK and we are able to use our custom board with DDR changes since one and half month. So, DDR changes are fine and having above issue with TI FIRMWARE BUILDER and Processor SDK.

Jay

For any memory change you will need firmware builder package.

Let me know if you are following firmware builder user guide before making the changes.

Thanks

Hi Yogesh,

We have firmware builder package version 09.01.00.07. We are following the firmware builder guide as well. But we haven't seen the steps to build firmware builder SDK where DDR is of different size.

Let us know if we are missing anything from builder guide.

Hi Yogesh,

I have one question not related to this thread.

Will pre-build tiboot3.bin of SDK 09.01.00 work with pre-build tispl.bin of SDK 09.02.00? If these combination doesn't work than what could be the reason for this?

Hi Jianzhong,

Thanks for your support on the patches issue of LSC. Post applying the patches successfully, the issue seems to have resolved.

However, after tuning LSC from DCC tool I am observing ring like patterns in the image. I am attaching below the image for the same. Do you have any idea what could be causing this?

Hi Viral,

Thanks for sharing!

Is the shared raw image in 1920x1200 Bayer pattern and linear 10-bit format?

Do you have phase of the Bayer pattern (e.g., RGGB or GRBG)?

Also, you use 960x540 as the image center and 41 as black level.
Are them both accurate?

Hi Viral,

There is nothing I can do with the shared jpep images.
Could you please share your raw and yuv images (for VISS input and output) alone with your LSC xml file?

Your LSC table has some places that are not very smooth.

But, I don't expect those would cause serious issues.
