3.9
Selectable 8 or 12 Bit Pixel Depth
When an
A102
f
camera is operating in Format 7, it can be set to output pixel data at either 8 bit or
12 bit depth.
3.9.1 A102f Monochrome Cameras
Set the value in the Format field of the Current Video Format register (see page
4-16
) and the
value in the Mode Field of the Current Video Mode register (see page
4-15
) so that the camera
will operate in Format 7, Mode 0.
For 8 Bit Depth
Set the value in the Coding ID field of the Color Coding ID register for Format 7, Mode 0 to Mono
8 (see Section
3.12.2
and page
4-27
). With this ID set, the camera outputs 8 bits per pixel.
For 12 Bit Depth
Set the value in the Coding ID field of the Color Coding ID register for Format 7, Mode 0 to Mono
16. With this ID set, the camera outputs 16 bits per pixel but only 12 bits are effective. The effective
pixel data fills from the LSB and the unused bits are filled with zeros. Pixel data is stored in the PC
memory in little endian format, i.e., the low byte for each pixel is stored at the lower address and
the high byte is stored at the neighboring higher address.
3.9.2 A102fc Color Cameras
Set the value in the Format field of the Current Video Format register (see page
4-16
) and the
value in the Mode Field of the Current Video Mode register (see page
4-15
) so that the camera
will operate in Format 7, Mode 0.
For 8 bit depth
Set the value in the Coding ID field of the Color Coding ID register for Format 7, Mode 0 to either
Mono 8 or Raw 8 (see Section
3.13.2
and page
4-27
). With either of these IDs set, the camera
outputs 8 bits per pixel.
When the Mono 8 color coding ID is set, the camera outputs 8 bits per pixel and outputs only the
Y component (brightness) of the YUV format.
When the Raw 8 color coding ID is set, the camera outputs 8 bits per pixel and outputs the raw
data for each pixel. (The pixel data is
not
processed to account for the color filter.)
For 12 bit depth
Set the value Coding ID field of the Color Coding ID register for Format 7, Mode 0 to Raw 16.
When the Raw 16 color coding ID is set, the camera outputs 16 bits per pixel and outputs the raw
data for each pixel. (The pixel data is
not
processed to account for the color filter.) Although the
camera outputs 16 bits per pixel in this mode, only 12 bits are effective. The effective pixel data
fills from the LSB and the unused bits are filled with zeros. Pixel data is stored in the PC memory
in little endian format, i.e., the low byte for each pixel is stored at the lower address and the high
byte is stored at the neighboring higher address.

When a camera is operating in a mode that outputs 16 bits per pixel, the maximum
frame rate at full resolution is 11.3 fps.
