Please make sure the camera is connected correctly.

5.2.1 Resolution and frame rate.

You can set the width, the height and the rate of the frame.

5.2.2 Fixed frame geometry

In this mode, any changes in the frame rate will have no effect in the geometry of the frame.The RoI is

frozen.

5.2.3 Fixed frame rate

In this mode, the changes at the geometry will be accepted if it has no effect on the given frame rate.

For this frame rate the maximum allowed frame height will be calculated.

5.2.4 Region of interest centered

If this option is checked the frame and the camera sensor have the same center.

CoI has null offset to the sensor center.

5.2.5 Black level

With the black level parameter (controlled with slider or text field) you may adjust the camera’s image

sensor base black level. The base black level must be set to a value between 0 and 255. Setting to the

correct value, the sensor will deliver the pixel value 0 (which means totally black) for a complete black

image.

If the value is too small, the sensor will deliver a pixel value above 0 (which means gray).

If the value is too big, the sensor will deliver a pixel value 0 (totally black) for images, that are gray and

not completely black.

The whitebalance form (for color cameras) or the histogram form (for monochrome cameras) is a good

tool for adjusting the black level:

In live mode, close the lens of the camera for getting a completely black image, adjust the black level

until the black line in the whitebalance or the histogram touches the “min” border of the chart.

5.2.6 Gain

The gain may be adjusted with the ComoBox “digital gain” or with the “analog gain” slider. You may

increase the digital gain up to 4, the analog gain up to 2. But please note: the quality of the image de-

creases the more you increase the gain.

5.2.7 Type of exposure

The MC13xx can expose the images synchronous or asynchronous. An external signal on CC1 can be

used to synchronize MC13xx cameras to each other or to an external event.
