raw image 10-bit to 16-bit


I have a raw image with only one channel (b/w) of 10-bit per pixel.
I need to convert the raw data to 16-bit per pixel.

Can I use a linear conversion or shall I use any formula to do that?

What I'm doing now is a linear conversion. OUT = IN * 65535/1023.

Simple answer: yes

Look at it in this way: transform the 10 bit signal to an analogue signal (DA conversion) and then resample it at 16 bit (AD conversion). So the formula you gave is what you need. There is nothing fancy about it.

Ofcourse you must round the new value to the nearest integer and then everything is as fine as you could get it. Normaly you won't see the difference at all since the max error is 0.5 on 65535 or less then 0.001%

I hope this answers your question.
kind regards,
