TDA3MV: TDA3 USE ISP

Kim TaeJung

Part Number: TDA3MV

I want to display the format below on my ISP.

    info->width             = 640;
    info->height            = 480;
    info->dataFormat        = SYSTEM_DF_YUV422I_UYVY;
    info->bpp               = SYSTEM_BPP_BITS8;
    info->features          = ISS_SENSORS_THERMAL_FEATURES;

After connecting to the link and running it, I get the following error.

IssCapture -> IssM2mIsp -> Display_Video

[IPU1-0]      2.229854 s:  ISSCAPTURE: Create in progress !!!

I think it's coming from the BPP side. Could the format settings be incorrect?

According to the link below, my ISP doesn't support YUV input. Is that correct?

IssM2mIsp does not support YUV input.

Hi Gang

Is it possible to configure the link below if it is not in YUV format?

IssCapture -> IssM2mIsp -> Display_Video

Kim

I am not familiar with S/W details.

From the H/W perspective, ISS takes raw input images in Bayer pattern format and produces YUV output.

How do I get S/W support?

IssCapture -> Alg_Thermal1 -> Alg_Thermal2 -> Display_Video

We're displaying a 14-bit RAW thermal camera image as shown above.

We'd like to add a RESIZE function in the middle.

What would be a good way to configure this?

Kim

I am not sure about S/W support for TDA3.
Copying my friend Brijesh Jadav for his comments.

I suppose you mean resizing the output of Alg_Thermal1.

Is the resizing I/O also in 14-bit monochome format?

Yes, that's correct. I'd like to resize the data after Alg_Thermal1 or Alg_Thermal2.

The output is in Y14 format.

Resizing Y14 images is not supported by TDA3 ISS or DSS.
I suppose you would have to do the resizing in S/W on the C66 DSP or EVE processor.

Hi Gang

Is it not possible to convert to YUV format using issm2misp?

If ISP support is 14-bit, would it be okay to change the format to 12-bit?

ISP resizer input/output are both in 8-bit.

I believe your resizer is for 14-bit input/output.

Kim TaeJung said:

I am not sure if I understand your questions.

As we discussed earlier, issm2misp can convert Bayer pattern input to 8-bit YUV output.

What is this 12-bit format used for?

Sorry I think there was some confusion in the question.

The camera input is y14. The output from the DSP can be in any format. I'm looking for a way to avoid resizing the image in the DSP.

Kim

ISS and DSS resizers are both from 8-bit to 8-bit.
You may have to convert your Y14 to Y8 first in DSP/EVE if you want to use ISS/DSS resizers.

Kim TaeJung said:

I am not sure if there is any DSP/EVE library available for resizing 14-bit or 12-bit images.
That seems a better option in my opinion.

So, given the current situation, ISP and RESIZE are not available, correct?

Does RESIZE input support Y8?

If possible, I'd like to RESIZE on ISS.

As we discussed above, both ISS and DSS resize (dss_m2mwb, iss_m2mresizer) are from 8-bit to 8-bit.
