Hello,

I was trying to reprocess using nvmipp_file , the output is .yuv. when I use convert command to convert the image to .png . the image is too dark.

command used : ./nvmipp_file -cf -c --bayrer-format GRGB --nvbracketae -i -o < output file name>

then command used to process .yuv

convert -size 1920x1236 -sampling-factor 4:2:0 -depth 8 raw-example.yuv -colorspace RGB out.png

the output image is very dark .?

  1. does the nvmipp-file use hardware isp to reprocess raw or it isues hardware isp.
  2. if it uses hardware isp why images saved are so dark

thanks

Dear xmnav,

Sorry for late update, Xavier doesn’t support nvmipp_file so please use nvmipp_raw, nvmimg_cap,
nvmimg_cc instead of nvmipp_file. Thanks.

Steve,

can you please let me know which of the command can process .raw file through hardware isp not software isp.

while I was checking nvmimg_cc -h this command does not save or reprocess .raw file
nvmipp_raw -h this command does not reprocess raw.
nvmimg_cap -h this command also does not reprocess.

Can you help here.

I am looking to reprocess raw through hardware isp.

thanks

Dear xmnav,

For HW ISP – Could you please refer to Image Signal Processing (ISP) and Capture parts in DriveSoftware doc?

It will be “nvmipp_raw” that will exercise HW ISP for raw capture input data. Thanks.

Hello Steve,

thanks for pointing the documents to me,

I have been going through these documents for a while, but these documents don’t show me how do I re-process .raw through nvmipp_raw

I can capture raw and jpg using nvmipp_raw but I am not able to " reprocess" captured raws.
if nvmipp_raw is capable of reprocessing can you please provide the command.

thanks

Dear xmnav,

Unfortunately, nvmipp_raw, nvmimg_cap, nvmimg_cc don’t support --reprocess option. Thanks.

Can you please provide the command to reprocess raw images through xavier .nvmippfile does work but the output is dark as the ouput is not tone mapped.

can you please check with the team or tuning team . they would be using the reprocessing option.

thanks
