Video Formats, Modes And Bandwidth - AVT Pike Technical Manual

Video formats, modes and bandwidth

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.
• For information on bit/pixel and byte/pixel for each
color mode see
Note The following Format_7 tables show default Format_7
modes without Format_7 mode mapping.

Note H-binning means horizontal binning.
V-binning means vertical binning.
Full binning (H+V) means horizontal + 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.
