Triggering image acquisition Setting the exposure time Controlling the camera’s image acquisition rate Variation of the camera’s maximum allowed image acquisition rate according to the camera settings Overview This section presents an overview of the elements involved with controlling the acquisition of images.
Page 24
VA GigE series Exposure Start Trigger Applying an exposure start trigger signal to the camera will exit the camera from the waiting for exposure start trigger acquisition status and will begin the process of exposing and reading out a frame (see Figure 8.1). As soon as the camera is ready to accept another exposure start trigger signal, it will return to the waiting for exposure start trigger acquisition status.
Page 25
VA GigE series Applying Trigger Signals The paragraphs above mention "applying a trigger signal". There are two ways to apply an exposure start trigger signal to the camera: via software or via external (commonly referred to as hardware). To apply trigger signals via Software, you must set the Trigger Source parameter to Software. At that point, each time a Trigger Software command is executed, the exposure start trigger signal will be applied to the camera.
VA GigE series Acquisition Start/Stop Commands and Acquisition Mode Executing an Acquisition Start command prepares the camera to acquire frames. You must execute an Acquisition Start command before you can begin acquiring frames. Executing an Acquisition Stop command terminates the camera’s ability to acquire frames. When the camera receives an Acquisition Stop command: ...
VA GigE series Exposure Start Trigger The exposure start trigger is used to begin frame acquisition. Exposure start trigger signals can be generated within the camera or may be applied externally as Software or External exposure start trigger signals. If an exposure start trigger signal is applied to the camera, the camera will begin to expose a frame.
Page 28
VA GigE series Continuous: The camera will automatically begin generating exposure start trigger signals when it receives an Acquisition Start command. The camera will continue to generate exposure start trigger signals until it receives an Acquisition Stop command. Free Run ...
Page 29
VA GigE series 8.3.1.2 Trigger Mode = On When the Trigger Mode parameter is set to On, you must apply an exposure start trigger signal to the camera each time you want to begin a frame acquisition. The Trigger Source parameter specifies the source signal that will act as the exposure start trigger signal.
VA GigE series 8.3.2 Using a Software Trigger Signal If the Trigger Mode parameter is set to On and the Trigger Source parameter is set to Software, you must apply a software trigger signal (exposure start) to the camera to begin each frame acquisition. Assuming that the camera is in a waiting for exposure start trigger acquisition status, frame exposure will start when the software trigger signal is received by the camera.
VA GigE series 8.3.3 Using an External Trigger Signal If the Trigger Mode parameter is set to On and the Trigger Source parameter is set to External, an externally generated electrical signal injected into the Control Receptacle pin 1 will act as the exposure start trigger signal for the camera.
Page 32
VA GigE series 8.3.3.1 Exposure Modes If you are triggering the start of frame acquisition with an externally generated trigger signal, two exposure modes are available: Timed and Trigger Width. Timed Exposure Mode When the Timed mode is selected, the exposure time for each frame acquisition is determined by the value of the camera’s Exposure Time parameter.
Page 33
VA GigE series Trigger Width Exposure Mode When the Trigger Width exposure mode is selected, the length of the exposure for each frame acquisition will be directly controlled by the external trigger signal. If the camera is set for rising edge triggering, the exposure time begins when the external trigger signal rises and continues until the external trigger signal falls.
VA GigE series 8.3.3.2 Double Exposure When the Double Exposure mode is selected, two frames can be acquired in rapid succession using a single trigger signal. The exposure time for the first frame begins according to the current camera settings when the trigger signal is applied to the camera.
VA GigE series Setting the Exposure Time This section describes how the exposure time can be adjusted manually by setting the value of the exposure time parameter. If you are operating the camera in any one of the following ways, you must specify an exposure time by setting the camera’s Exposure Time parameter:...
VA GigE series Overlapping Exposure with Sensor Readout The frame acquisition process on the camera includes two distinct parts. The first part is the exposure of the pixels in the imaging sensor. Once exposure is complete, the second part of the process – readout of the pixel values from the sensor –...
Page 37
VA GigE series In the Trigger Overlap – Readout mode of operation, the exposure of a new frame begins while the camera is still reading out the sensor data for the previously acquired frame. Figure 8.8 illustrates the Trigger Overlap parameter set to Readout and the Exposure Mode parameter set to Trigger Width.
Page 38
VA GigE series Guidelines for Overlapped Exposure If you will be operating the camera with overlapped exposure, there are two important guidelines to keep in mind: You must not begin the exposure time for a new image acquisition while the exposure time of the previous acquisition is in progress.
VA GigE series Real Exposure 8.6.1 Timed Exposure Mode When the Timed mode is selected, the exposure time is determined by the time interval between the point where an external trigger signal is applied and the point where the t (Photodiode Transfer) signal falls.
VA GigE series 8.6.2 Trigger Width Exposure Mode When the Trigger Width mode is selected, the exposure time is controlled by the external trigger signal. The camera generates a shutter signal to clear pixels when an external trigger signal is applied. The exposure time begins when the shutter signal falls and continues until the tpd (Photodiode Transfer) signal falls.
Page 41

VA GigE series Maximum Allowed Frame Rate In general, the maximum allowed acquisition frame rate on the camera may be limited by several factors: The amount of time that it takes to transmit an acquired frame from the camera to your computer.
VA GigE series 8.8.1 Increasing the Maximum Allowed Frame Rate You may find that you would like to acquire frames at a rate higher than the maximum allowed with the camera’s current settings. In this case, you must adjust one or more of the factors that can influence the maximum allowed frame rate and then check to see if the maximum allowed frame rate has increased: ...
VA GigE series 9 Camera Features Image Region of Interest The Image Region of Interest (ROI) feature allows you to specify a portion of the sensor array.
