TDA4VH-Q1: ISP uses LSC module, the output image appears red stripe.

es bsp
Expert 1930 points
Part Number: TDA4VH-Q1

Tool/software:

I added the LSC module to the ISP, where the LSC LUT used the MATLAB code provided by the TI official documentation, and the data format tried U8Q8 + 1 and U6Q6 + 1, but the LSC module did not seem to work properly, the resulting image shows an unusual red stripe, as shown below. However, when I set LSC LUT's gain to 1, the image output is normal without the red stripe

    Hi es,

    Do you get the issue in tuning tool or on H/W?

    I suppose you are working with J721s2 (VPAC3).

    Please share your LSC xml file.

    Hi es,

    That is the LUT text file (not the xml file).

    Could you please share the complete LSC xml file exported from tuning tool?

    Expert 1930 points

    Do you mean the full configuration includes XML like GAINFMT? I didn't used the tuning tool, I just configure the following.

    GAINFMT: U6Q6 + 1,

    Horzdsfactor: 64

    vertdsfactor: 64

    numtblentry: 1891

    3840*1888

    The LUT size and content look correct for 3840x1888.

    Do you store and pass the LUT to VISS driver correctly?

  • 0 in reply to Gang Hua
    Expert 1930 points

    I confirm that this is true, and the fact that there are no exceptions when Lut's gain is all 1 should also prove this

    Hi es,

    I suppose you don't use xml files and DCC for configuring LSC.
    Do you use both PDK driver and tiovx kernel for VISS?

    There is no known LSC issues on our side in either PDK driver or tiovx.

    Could you please share a test case with the problem?

    BTW, I have confirmed that your LUT above is correct.

    Can I read the parameters I set? This will make sure that what I write is the same as what I set. If there is such an interface, please provide it to me

    Hi es,

    es bsp said:

    There is no known issues in PDK for LSC.
    As long as you pass the correct LSC parameters to PDK driver, LSC should work properly.
    You may print or check the LSC parameters while calling the PDK driver.

    Hi es,

    We tried using your LUT with tuning tool generated LSC xml file on J784S4 EVM and it works well.
    You might have some bug in your code.
