Hello,

 

My customer is using ADV212 for compressing 16 bit RAW Pixel data in HIPI mode.

But they got some issues using ADV212.

When they handle 8 bit Raw data piexel data, they say that they can compress normally.

But when they handle 16 bit Raw piexel data, they find this compressed data has some issues.

It seems that low 8bit data don't be recovered when they decode this compressed data using Matlab.

 

Please refer below examples related 16 bit Raw piexel data.

 

 

Would you confirm this issue of ADV212?

 

If you have any questions, please let me know.

 

Regards,

Se-woong

 

PS. For your information, I attached a schmatic,block diagram, parameter setting of register & firmware and etc.
