Color Codlings
In Format 7, Mode 0, the Mono 8, Raw 8, Raw 16, and YUV 4:2:2 color codlings are available.
When the Mono 8 ID is set in the Coding ID field of the Color Coding ID register for Format 7,
Mode 0, the camera outputs 8 bits per pixel and outputs only the Y component (brightness) of the
YUV format.
When the Raw 8 ID is set in the Coding ID field of the Color Coding ID register for Format 7, Mode
0, 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. (This type of output is sometimes called “Bayer 8.”)
When the Raw 16 ID is set in the Coding ID field of the Color Coding ID register for Format 7,
Mode 0, 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 Indian 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. The camera outputs raw data for each pixel. The
pixel data is not processed to account for the color filter.
When the YUV 4:2:2 ID is set in the Coding ID field of the Color Coding ID register for Format 7,
Mode 0, the camera outputs image data in the YUV 4:2:2 format at an average of 16 bits per pixel.
Format 7, Mode 1
Format 7, Mode 1 is very similar to Format 7, Mode 0 with the exception of the available color
codlings and how the color codlings work.
Format 7, Mode 1 is parameterized by using the Format 7, Mode 1 control and status registers
(see page 4-34).
Color Codlings
In Format 7, Mode 1, only the Mono 8 color coding is available and the color coding works
differently than the Mono 8 color coding available in Format 7, Mode 0.
When the Mono 8 ID is set in the Coding ID field of the Color Coding ID register for Format 7,
Mode 1, 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. (This type of output is sometimes called “Bayer 8.”)
This mode of operation is included on the A102
fc for compatibility with versions 1.6 and below of
the Basler BCAM 1394 driver software. These early versions of the BCAM software require a
Mono 8 color coding that results in the output of raw pixel data.
L
When the camera is set for the Raw 16 or the YUV 4:2:2 color coding, the maximum
frame rate at full resolution is 11.3 frames/s.
The Raw 8 and Raw 16 color codlings are defined in version 1.31 of the IIDC specifi-
cation.
Color code definitions can very from camera model to camera model. This is especially
true for older models of Basler cameras.
