Camera Properties acquisition frame rate and may cause artifacts to appear in the image. o If the object is moving, choose a low exposure time setting to prevent motion blur. As a general rule, choose a short enough exposure time to make sure that the image of the object does not move by more than one pixel during exposure. A shorter exposure time setting may require a higher illumination level. Acquisition parameters are validated before being sent to the camera. If you enter an exposure time that your camera does not support, the time will be adjusted to be valid. If you haven't typed in an invalid exposure time, the left and right arrows will provide valid times.
l Gain is the amplification of the signal being sent from the camera. The readout from each pixel is amplified by the Gain, so both signal and noise are amplified. This means that it is not possible to improve the signal-to-noise ratio by increasing gain. You can increase the contrast in the image by increasing the camera’s gain setting. Unless your application requires extreme contrast, make sure that detail remains visible in the brightest por- tions of the image when increasing gain. Note also that noise is increased by increasing gain. Increasing gain will increase the image brightness. Set the gain only as high as is necessary.
l Black Level is an offset, which is used to establish which parts of an image should appear black. High black level settings will prevent high contrast. Make fine adjustments to the Black Level to ensure that detail is still visible in the darkest parts of the acquired images. Balance Red, Balance Green, and Balance Blue are only available if your ACE dongle has the color license enabled and you have a color camera connected. On some Basler color cameras, such as the A601fc-2, the green balance is a fixed value that cannot be adjusted. In such cases, only the balance for blue and red will be enabled in this window- Balance Green will be greyed out.
Trigger The Trigger tab lets you enable an external trigger for taking a picture, and set parameters that pertain to that trigger. ACEUser's Guide, 3.6.x, 18316-000 Rev A Page 340
