Hinweis

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

Under Linux not all settings for USB uEye XS are available in uEye Demo (uEye Cockpit).

On this tab, you can set the functionality provided by the USB uEye XS camera model. See also the uEye XS (2) tab.

Achtung

Note on image resolution

Images larger than 1280 x 720 pixels can only be captured in software trigger mode.

Hinweis

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.

•HS mode
Enables the High sensitivity mode.

Hinweis

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.

oPosture
The face detection feature can distinguish 9 different viewing directions or postures of the head. The detected posture is indicated by a symbol.

oAngle
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.

ox/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.

Achtung

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.
