This tab is only available when a USB uEye XS camera (UI-1008XS) has been opened in uEye Demo.

Note on image resolution
Images larger than 1280 x 720 pixels can only be captured in software trigger mode.
|
|

|
Note on image stabilization
• | Enable automatic exposure time control for best image stabilization results (see is_SetAutoParameter()). |
• | The image is stabilized electronically using part of the field of view for movement compensation. When this function is enabled, the visible field of view is reduced by about 10%. |
• | The image stabilization feature at the same time activates the USB uEye XS camera's anti-flicker function. |

Image
With these settings, you can configure the image capture parameters for the USB uEye XS.
• | Size (Live) / Size (Trigger)
This selection box lists all the image sizes that are supported by the sensor in the current operating mode. Using the AOI, binning/subsampling or scaling functions, the driver sets the selected image format to achieve the best possible image quality. |
• | Mirror left/right / Mirror up/down
Select this check box to flip the image horizontally/vertically. |
• | Image stabilization
Enables the camera's electronic image stabilization feature. |
|

|
Note on face detection
• | Upside-down faces are not detected. You have to turn the camera or enable the mirror function in order to detect upside-down faces. |
• | The position and size coordinates of the detected faces are independent of the image size setting. The coordinates are in a range from 0...320 in X direction and 0...240 in Y direction. The coordinate (0,0) is at the top left corner of the image. |

Face detection
With these settings, you can configure the face detection feature of the USB uEye XS.
• | Search angle
To increase the detection reliability when the camera is turned upright, you can preset a facial orientation angle (search angle). An angle of 0° corresponds to the 12 o'clock position, all other angles apply clockwise. |
• | Number of faces marked
Here you can select how many of the faces detected should be marked with a border in the camera image. The detected faces are marked with an overlay box. The box marking the largest face detected has a green border, the boxes for the other faces have white borders. |
• | Max. number of detected faces / Number of detected faces
These fields indicate up to how many faces the current camera model can detect and how many faces have been detected in the current image. |
• | List of detected faces
This list provides information on the faces detected in the current image. The faces are sorted by size. |
o | Posture
The face detection feature can distinguish 9 different viewing directions or postures of the head. The detected posture is indicated by a symbol. |
o | Angle
Orientation of the current face in degrees (0/90/270). An angle of 0° corresponds to the 12 o'clock position, all other angles apply clockwise. |
o | x / y / height
Position and size of the face. |
• | Overlay width
Here you can set the line width for the overlay boxes that indicate the detected faces. |
|

Note on the focus
According to the sensor manufacturer, there is no guarantee that a focal point set manually for the uEye XS will lead to a reproducible focal distance. A focal value determined with one uEye XS model will not necessarily result in the same focal point for a different model.

Focus
With these settings, you can configure the integrated optics of the USB uEye XS.
• | Auto focus
Enables the built-in automatic focus. |
• | Object distance
Displays the object distance to which the focus is set (far/near/macro). |
• | Read
Reads out the current object distance. |
• | Manual focus
Manual setting of the focal point. |
