IDS Software Suite 4.96.1

This tab provides the settings for triggered image capture with your uEye camera (see also Digital inputs/outputs).

Input

•Status
If you select this check box, the signal level applied at the camera's trigger input is polled and displayed.

•Trigger delay (frame rate)
Select this check box to set a delay between the arrival of a software or hardware trigger signal and the start of exposure.

Mode

With these radio buttons, you choose which trigger mode you want to activate in the camera:

•Software
The camera is running in software trigger mode without a signal applied. The images are captured continuously.

•Falling edge
The camera captures an image on the falling edge of the signal applied to the trigger input.

•Rising edge
The camera captures an image on the rising edge of the signal applied to the trigger input.

•Burst size
Number of images in a trigger burst (is_Trigger()). The maximum number is 1023 images.

•Trigger timeout [ms]
Specifies a timeout for the trigger mode. If the camera does not receive a trigger signal within this time, a timeout message is transmitted and the transmission error counter is incremented (see is_SetTimeout()).

Debounce

With this function, you can suppress disturbances at the digital input when you are running a USB 3 or GigE uEye camera in trigger mode. The signal at the digital input is only recognized as a trigger if the signal level remains constant at the target level for a user-selectable time. The signal edge and a delay can be set as parameters. It is recommend to use automatic signal edge selection (see is_TriggerDebounce()).

Example: Mode set to "rising edge" and delay set to 50 µs. The camera will not trigger the image capture on the rising edge until the digital signal has remained at the high level for longer than 50 µs without interruption. If this is not the case, the signal is regarded as a disturbance and ignored.

•Mode
Sets the signal edge to be suppressed.

•Delay
Delay time until a signal will be recognized as trigger.

Camera

•Global start (trigger mode)
If you select this check box, all rows of a rolling shutter sensor are exposed simultaneously. Activating Global start only makes sense when using a flash. This function is not supported by all models.

Prescaler

Via the trigger prescaler (frequency divider) you can set for some uEye models that the trigger signal is divided by the set value. This is necessary when the trigger signal delivers more pulses as needed for the captures. With the set value, e.g. 40, you define that the camera captures an image only every 40th trigger signal (is_Trigger()).

•Frame
Trigger prescaler for image recordings (value range: 1–64)

•Line (only when using AOI merge mode)
Trigger prescaler for line recordings (value range 1–64)

Resetting the parameters
