How to capture 12 bit ( = 4096 grayscale levels) images

edit

Hi there, I would ask you if there is the possibility to capture images that use 12 bit to represent the brightness intensity of pixel, equivalent to 4096 grayscale levels per pixel.

I know that the image format (L8, R8G8B8, etc.) can be specified using the SDFormat. For instance, L8 correspond to a grayscale image that used 8 bits per pixel, that is 256 grayscale levels.

Thank you in advance!
