Quote from the SANE standard (3.2): "Valid bit depths are 1, 8, or 16 bits per sample. If a device's natural bit depth is something else, it is up to the driver to scale the sample values appropriately (e.g., a 4 bit sample could be scaled by a factor of four to represent a sample value of depth 8)."
