IDS peak 2.8.0 / uEye+ firmware 3.33

Image acquisition

•If you increase the exposure time so that the frame rate drops, a single image can be defective.

•To achieve the maximum frame rate, you must set DeviceLinkThroughputLimit to the maximum value.

•To achieve the minimum exposure time, you must set DeviceLinkThroughputLimit to the maximum value.

•To achieve the maximum exposure time, you must set DeviceLinkThroughputLimit to the minimum value.

•As the models do not have an image memory, images may be lost under certain circumstances. In this case, reduce the value of DeviceLinkThroughputLimit. Note, however, that this lowers the frame rate and may cause a rolling shutter effect.

•From firmware version 2.11 on, it is possible to change the frame rate or exposure time of the uEye XLE USB 3 or uEye XCP USB 3 during freerun operation. With previous firmware versions, it was necessary to stop image acquisition to change the frame rate or exposure time.

ROI

•The frame rate does not increase by the use of a horizontal ROI.

Binning

•The model supports sensor binning only in 10-bit mode.

•Binning can only be set vertically and horizontally at the same time.

Decimation

•The model does not support decimation.

Flash

•The sensor does not support flash.

Pixel format

•The model currently supports only IDS-specific pixel formats.

Trigger

Due to the sensor, the sensor is operated in freerun mode in the "ReadOutStart" trigger mode. This means that when a trigger signal arrives, the next image from the sensor is acquired and transmitted. Depending on the temporal relation to the running sensor the trigger signal arrives, the image is therefore transmitted earlier or later after the trigger signal. For example, you must wait for the next image if the trigger is received while an image is being transmitted.

This causes beat effects if the frequency of the trigger does not match the frequency of the sensor. The maximum value of AcquisitionFrameRate indicates the frame rate at which the sensor is running. If you trigger periodically and the trigger rate is greater than the maximum value of the frame rate, all images of the sensor will be acquired. With single trigger signals, each signal triggers an image, although the image may arrive earlier or later.

Special case: If you trigger a second time while the first image is still being transmitted, the next image will also be acquired. The 2nd image follows directly after the 1st image with a time interval of 1/frame rate. For example, if the sensor is running at 10 fps and is triggered at 7 Hz, 7 images will be received because each signal triggers one image. Without the special case, of the 7 trigger signals, some signals would conflict with the image acquisitions of the previous image and would be lost.
