5.2.5 Y16 (16-bit Mono) Image Acquisition
The camera can output Y16 (16 bits-per-pixel) mono images. Because the camera's A/D converter is less than 16 bits,
unused bits are zero.

The PGM file format can be used to correctly save 16- bit images. Although the availability of photo
manipulation/display applications that can correctly display true 16-bit images is limited, XV in Linux and Adobe
Photoshop are two possibilities.
5.2.5.1 DATA_DEPTH: 630h
This register allows the user to control the endianness of Y16 images.
Field Bit Description
Data_Depth [0-7]
Effective data depth of current image data.
If read value of Data_Depth is zero, shall ignore this field.
Read: Effective data depth
Write: Ignored
Little_Endian [8]
Little endian mode for 16-bit pixel formats only
Write/Read:
0: Big endian mode (default on initialization)
1: Little endian mode
[9-31 Reserved
Format:
5.2.6 Y8 or Y16 Raw Bayer Output
When operating in Y8 or Y16 mode, color models can output either grayscale or raw Bayer data.
Selecting a half- width, half- height image size and monochrome pixel format, such as
800x600 Y8, using a non-Format 7 mode provides a monochrome binned image. In some
cases, enabling raw Bayer output in mono mode provides a raw Bayer region of interest of
800x600, centered within the larger pixel array. This has an effect on the field of view.
5.2.6.1 BAYER_MONO_CTRL: 1050h
This register enables raw Bayer output in non-Format 7 Y8/Y16 modes, or Format 7 Mono8/Mono16 modes.
