Exposure Controls
The Exposure controls allow you to customize your application to better handle inconsistent lighting and balance brightness to maximize the detail of the features in your inspection.
Exposure
The Exposure control allows you to specify the exposure time. When the In-Sight vision system receives a trigger signal, light is integrated in the image sensor array for the specified duration.
- For the following vision systems/sensors, the resolution can be configured in the Image Settings dialog: In-Sight Micro 1500, In-Sight 2000-130, 2000-130C, 2000-230, 2000-230C, 2000-23M, 2001-230, 2001-230C, In-Sight 7500, 7600, 7600C, 7800, 7800C, 7900, 7900C, 7802, 7802C, 7902, 7902C.
- For the 5604 and 5614 line scan vision systems, the Image Height can be configured in the LineScan Settings dialog.
- For the 9902L line scan vision system, the 1K Resolution (Low Light Mode) and Max Image Height can be configured in the LineScan Settings dialog.
- When connected to an In-Sight 5604, 5614 or 9902L line scan vision system, the exposure time is set in microseconds.
- If using a strobe with the In-Sight 8405 vision system, a minimum Exposure value of 72ms is recommended for a full frame image capture, to ensure that all pixel rows are exposed when the strobe is pulsed.
-
While the Exposure may technically be set to 0, the Exposure time is In-Sight vision system dependent, and an Exposure value of 0 will default to the minimum exposure time (in milliseconds or microseconds) for the selected vision system.

Auto-Exposure
The Auto-Exposure control allows the vision system to automatically determine the exposure. This control helps to compensate for inconsistent lighting conditions, such as reflections from shiny metal surfaces, shifting shadows and background lighting changes.
-
Continuous: Activates the vision system to automatically adjust the exposure, depending upon light conditions, for every image acquisition.
Note: Time between acquisitions is increased while in Continuous mode. - Single-shot: Single-shot adjusts the vision system's exposure based on the first image acquisition; the exposure settings will remain for each subsequent image acquisition.
- First Acquisition: If the vision system is Offline, the first acquisition is used to determine exposure and the exposure value is stored until Single-shot is disabled. If no acquisition has occurred while the vision system is Offline, when it is put Online, the first acquisition is used to determine exposure.
- Subsequent Acquisitions: The vision system will acquire the image using the exposure value that was calculated at the first acquisition.
Note:- If the vision system or vision sensor does not support this feature, it is not displayed.
- Selecting a different Auto Exposure mode will reset the exposure value. The first acquisition, after the exposure value has been reset, will be used to determine a new exposure value.
Exposure Region button
Defines the Region to use when automatically calculating the exposure.
- Click the Exposure Region button.
- Position the region around the image area that the sensor will use to determine the automatic exposure to use for the next acquired image.
- Click the OK button.
The exposure will now be calculated automatically based on the brightness of the image area within the Exposure Region. For example, if the image area within the Exposure Region is brighter than the rest of the image, then the next acquired image will be darker.
