Goldeye G/CL Technical Manual V4.1.1
Resolution and ROI frame rates
The maximum frame rate achievable with Goldeye G-008 models (in frames per
second — fps) is determined by the ROI size. Calculate the maximum frame rate
using the formula below.
Examples for maximum frame rates possible with Goldeye G-008 models, using a
number of common resolutions, are listed in the table below.
To achieve the highest possible frame rates for different formats, it may become
necessary to change the GigE streaming features, particularly to adjust the GigE
packet size.
•
Smaller packets may be advantageous if using small ROIs
•
Larger packets may be advantageous if using larger ROIs
H
ROI: horizontal resolution (width).
The formula is valid if H
≥
128. For H always use the value rounded up
to the next multiple of 8.
V
ROI: vertical resolution (height).
The formula is valid if V
≥
8. For V always use the value rounded up to
the next multiple of 2.
When using the formula, please consider the following:
•
Round the denominator down to the next full µs.
•
Minimum ROI width is 8 pixels, minimum ROI height is 4 pixels.
•
The formula generally outputs very exact values, however when the ROI
approaches its minimum size, the exactness decreases by some degree.
•
Computational limitations of the host and image capture software may pre-
vent the camera from achieving maximum frame rates.
