Information on NV21 preview format

Postby quanganht » Fri Mar 11, 2011 12:13 pm

I have done some google-ing around and couldn't find enough information about this format. It is the default format for camera preview. Can anyone suggest good sources of information about it and how to extract data from a photo/preview image with that format? To be more specific, I need the black and white image extracted.
Thanks in advance. :mrgreen:

EDIT: Seems like that format is also called YCbCr 420 Semi Planar
