Description of the data path
Binning and sub-sampling access
(only Guppy F-503)
The binning and sub-sampling modes described in the last two chapters are only
available as pure binning or pure sub-sampling modes. A combination of both is
not possible.
As you can see there is a vast amount of possible combinations. But the number
of available Format_7 modes is limited and lower than the possible combina-
tions.
Thus access to the binning and sub-sampling modes is implemented in the fol-
lowing way:
• Format_7 Mode_0 is fixed and cannot be changed
• A maximum of 7 individual Allied Vision modes can be mapped to For-
mat_7 Mode_1 to Mode_7
(see Figure 82: Mapping of possible Format_7 modes to F7M1...F7M7 on
page 127)
• Mappings can be stored via register (see Chapter Format_7 mode mapping
(only Guppy F-503) on page 255) and are uploaded automatically into the
camera on camera reset.
•The default settings (per factory) in the Format_7 modes are listed in the
following table:
Note

Changing sub-sampling modes involves the generation of new
shading reference images due to a change in the image size.
