Video formats, modes and bandwidth
The different Pike models support different video formats, modes and frame
rates.
These formats and modes are standardized in the IIDC (formerly DCAM) spec-
ification.
Resolutions smaller than the generic sensor resolution are generated from
the center of the sensor and without binning.
Note
•
The maximum frame rates can only be achieved with
shutter settings lower than 1/framerate. This means
that with default shutter time of 40 ms, a camera will
not achieve frame rates higher than 25 frames/s. In
order to achieve higher frame rates, please reduce the
shutter time proportionally.
•
The following tables assume that bus speed is
800 Mbit/s.
With lower bus speeds (e.g. 400, 200 or
100 Mbit/s) not all frame rates may be achieved.

Note
H-binning
means horizontal binning.
V-binning
means vertical binning.
Full binning (H+V)
means hori vertical binning
2 x binning means: 2 neighboring pixels are combined.
4 x binning means: 4 neighboring pixels are combined.
•
Binning average
means: signals form adjacent pixels
are combined by averaging.
•
Binning increases signal-to-noise ratio
(SNR), but
decreases resolution.
