Note: BB-500GE has the same Bayer sequence for Full and any of partial scanning as RG.
Therefore, comparing full scanning and partial scanning, the center might be shifted.
Note: As the Pixel Format type, BB-500GE supports BAYER GB 8, BAYER GB 10 and BAYER
GB12. When this type is selected, the output starts from 2
nd
line for all scanning.
7.5. BB-500GE. Bayer mosaic filter
BB-500GE is a color camera based on a CCD
sensor with a Bayer RGB color mosaic.
The color image reconstruction is done in the
host PC. The Color sequence in the video signal
is the same for all scanning formats.
The line readout follows LVAL.
The first valid pixel is the same timing as DVAL.
The Bayer color sequence starts with:
RGR for odd line numbers.
GBG for even line numbers.
Figure 12 shows the timing sequence for the
Bayer mosaic read-out for the available partial
scan modes.
