Video formats, modes and bandwidth

The different Guppy models support different video formats, modes and frame

rates.

These formats and modes are standardized in the IIDC (formerly DCAM) specifi-

cation.

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

400 Mbit/s. With lower bus speeds (e.g. 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 Table 84: ByteDepth on page 193.

Note



H-binning means horizontal binning.

V-binning means vertical binning.

Full binning 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 com-

bined by averaging. Binning increases signal-to-noise ratio

(SNR), but decreases resolution.
