Sorry this has been asked and answered before here How to capture raw image from android camera , but I would like to have a different opinion.
Indeed I am not convinced that an image saved as .bmp is actually a raw image.
The above mentioned thread arguments that passing
Camera.Parameters parameters=previe.camera.getParameters();
parameters.set("rawsave-mode", "1");
Will give 10 bit RAW pictures, but from http://www.luminous-landscape.com/tutorials/understanding-series/u-raw-files.shtml I read that RAW should be 12 bit.
Additionally form Wikipedia http://en.wikipedia.org/wiki/Raw_image_format none of the mentioned RAW formats include .bmp extension.
Please if somebody could clarify or give any contribution that would be very much appreciated!
Thanks!
