Thank-you for your response. I am little bit confused about the
SET_NORM_TO16 versus the SET_NORM_TO8 ioctls. For a 10-bit camera (Pulnix),
which of these two ioctls should I have set, and do I need to use a lookup
table? Is it correct to assume that one of the two must be used? Having a
16-bit image in which only the lower 10 bits are used is fine with me.

I have presently gotten images (with some of the bits shifted, but not all)
using the  DG_SET_NORM_TO16 with DG_SET_LUT_LIN

Thanks,

Karen Daniels
