Acquisition Control
Acquisition and Frame Rate
There are three acquisition modes:
Continuous - acquires images continuously. This is the default mode.
Multi Frame - acquires a specified number of images before stopping acquisition.
Single Frame - acquires 1 image before stopping acquisition.
Use AcquisitionMode to select your mode. If you select MultiFrame, use AcquisitionFrameCount to specify the number of images to acquire.
Use AcquistionStart and AcquisitionStop to start and stop acquiring images with the selected mode.
The Acquisition Frame Rate can be manually or automatically controlled. Use AcquisitionFrameRateEnable to set this On (manual control) or Off (automatic control). By default, this is Off. If you select manual control, use AcquisitionFrameRate to specify a frame rate.
The ResultingFrameRate reports the actual frame rate at which the camera is streaming. If this does not equal the Acquisition Frame Rate it is because the Exposure Time is greater than the frame time.
Exposure Time Modes
There are two exposure time modes:
Timed - exposure time is a specified value. This is the default mode.
TriggerWidth - exposure time is controlled by the trigger signal.
Use ExposureMode to make a selection.
When ExposureMode is set to Timed, exposure time can be manually or automatically controlled.
For manual control, set ExposureAuto to Off. Use the ExposureTime control to set the exposure time in microseconds.
For automatic control, set ExposureAuto to Once or Continuous. The camera automatically adjusts the exposure to maximize the dynamic range. Once briefly enables automatic exposure to adapt the device and then sets exposure to manual control (Off). Continuous constantly adapts the device. Continuous is the default setting.
Note: For the Auto Exposure feature, gain and/or exposure time must be set to Continuous.
Trigger Features
Triggering allows you to acquire images at specific times when an event occurs. Triggering works with the acquisition modes and settings. By default, triggering is set to Off. To enable triggering, set TriggerMode to On.
Trigger Type - three options to control the start of triggering. Use TriggerSelector to select an option.
Acquisition Start - A trigger starts acquisition in the selected AcquisitionMode.
In Single Frame mode, the trigger acquires one image.
In Multi Frame mode, the trigger acquires the specified number of images.
In Continuous mode, the trigger acquires images until you stop acquisition.
Frame Start - A trigger is required for each individual image that is acquired.
In Single Frame mode, the trigger acquires one image. For each subsequent trigger you first must use AcquisitionStart to receive more images.
In Multi Frame mode, the trigger acquires the specified number of images. For each subsequent trigger you first must use AcquisitionStart to receive more images.
In Continuous mode, the trigger acquires one image. You do not have to start acquisition again for subsequent triggers.
Frame Burst Start - A trigger acquires a specified number of images. You do not have to start acquisition again for subsequent triggers. This mode is primarily used in Continuous mode, as Single Frame and Multi Frame settings overwrite the burst count. Use AcquisitionBurstFrameCount to specify the number of images to be acquired.
In Single Frame mode, the trigger acquires one image.
In Multi Frame mode, the trigger acquires the number of images specified in AcquisitionFrameCount.
In Continuous mode, the trigger acquires the number of images specified in AcquisitionBurstFrameCount.
Trigger Source - Use TriggerSource to specify the source that can signal the acquisition to acquire images. A trigger source can be one of the physical Line Inputs, User Outputs, Counters, Logic Blocks, and Software.
Trigger Activation - Use TriggerActivation to specify what voltage level or transition that activates a trigger. Trigger activation can be Level Low, Level High, Falling Edge, Rising Edge, or Any Edge.
Trigger Overlap - Use TriggerOverlap to specify whether a trigger responds while the readout of a previously acquired image is still occurring. There are two options: When set to Off, a trigger is disregarded during readout. When set to ReadOut, a trigger acquires another image during readout.
Trigger Delay - Use TriggerDelay to specify the time in microseconds between when the camera receives a trigger and when exposure begins for the image.
Trigger Software - If your trigger source is set to Software, use TriggerSoftware to perform a software trigger.
