Resolution and ROI frame rate
The maximum frame rate achievable with Goldeye CL-033 TEC1 (in frames per
second) is determined by the ROI size. Calculate the maximum frame rate using the
following formula.
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 32.
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 4.
When using the formula, please consider the following:
• Round the denominator up or 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 accuracy decreases by some degree.
• Computational limitations of the host and image capture software may prevent the camera from
achieving maximum frame rates.
