Image Acquisition Toolbox™

stop - Stop video input object

Syntax

stop(obj)

Description

stop(obj) halts an acquisition associated with the video input object obj. obj can be either a single video input object or an array of video input objects.

The stop function

• Sets the object's Running property to 'Off'

• Sets the object's Logging property to 'Off', if needed

• Executes the object's StopFcn callback

An image acquisition object can also stop running under one of the following conditions:

• The requested number of frames is acquired. This occurs when

  FramesAcquired = FramesPerTrigger * (TriggerRepeat + 1)
  

  where FramesAcquired, FramesPerTrigger, and TriggerRepeat are properties of the video input object.

• A run-time error occurs.

• The object's Timeout value is reached.

The stop event is recorded in the object's EventLog property.

Examples

The stop function can be called by a video input object's event callback.

obj.TimerFcn = {'stop'};
