Resolution and ROI frame rates

This section charts the resulting frame rate from changing sensor height from

full image to a single line.

Unless otherwise noted, sensors do not give an increase in readout speed with

a reduction in width. However, in cases where a camera is limited by frame rate

due to bandwidth restrictions, a reduction in width will give a frame rate

increase. Cameras with a “burst mode” frame rate (see Chapter Specifications

on page 26) are able to output more data than the maximum available band-

width (124 MB/s), and will see a frame rate increase with a reduction in width.

Note



• Data was generated using StreamBytesPerSecond = 124

MB/s (full bandwidth) and an 8-bit pixel format. Frame

rates may be lower if using network hardware incapable

of 124 MB/s.

• For maximum speed advantage on quad-tap CCD sensors,

ROIs are center image, where feature OffsetY = (full

sensor height – ROI height)/2.

• There is no frame rate increase with reduced width.

• BinningVertical is horizontal row summing on CCD

before readout. The frame rate for an ROI at the same

effective height as binning will be slower because the CCD

still needs to read out the “fast readout rows” in ROI

mode.
