Preview setting in DM365

Hi,

seol hee park said:

some of them, i only applied to CFA->RGB2RGB->RGB2YUV->422 Conversion function by \PSP_02_10_00_14\examples\dm365\previewer_resizer\do_preview_resize example source.

and image data output format is YUV422(UYUV). Is it  right?

The output format from the previewer+resizer can be either YUV422 format data or YUV420SP format data. You can select the output format using the configuration parameter "rsz_ss_config.output1.pix_fmt" in previewer-resizer example.

when it stored buffer,  data packing is Y1 Cr0 Y0 Cb0. is it right?

If you have selected YUV422 mode for output format, generally the format is U Y V Y.

BTW, can you share the YUV data that is generated in your data flow, which you think is not correct?

dear sir,

i attached image file .

first image is bayer raw data by mt9p031 and second image is YUV(422) by do_preview_resize example source.

bayer raw data is stored buffer by V4L2_PIX_FMT_SBGGR8. so,even if mt9p031 is 12bit data format but actually it's 8bit data.

<figure1>0707.raw

<figure2>0707.yuv422

as you see, YUV422 image is strange..almost white color...

refer to the below about do_preview_resize source setting.

i suspect YUV conversion in do_preview_resize example.

how can i get the normal YUV422 image?

and. i wana attached binary file but i can't find attached file menu..it possible only image file.

Hi,

I have few questions which might help us debug this issue further:

1. Did you try raw data that did not have A-law format data? I mean a normal 12 bit data?

2. Could you dump all the registers for IPIPEIF, IPIPE and RSZ?

3. could you also provide the input physical address where raw data is placed?

4. Although i believe you would have taken care, can you please ensure that you are saving the output data in the file from the correct output offset location?

5. Can you write your output buffer with some know pattern say 0xABCDEF12 and then run the previewer? This way we can atleast confirm if the output is coming or not from previewer/resizer

Regards.
