Hi All
I'm just bought Nook, which on the wiki says it has 16bit grey levels.
https://wiki.mobileread.com/wiki/Nook
I put some image pdf into it, and found that the images have very obvious boards between the colours.
Which looks like this image:

If the Grey level for ebook device is the same definition as the wiki
http://en.wikipedia.org/wiki/Grayscale
16bit should be enough for a picture, or 16 level means 4bit (16 levels of grey)?
Cheers
