The XS comes with built-in autofocus and offers many special features that are not available with other camera models. In this chapter, you will find an overview of the different features.

Autofocus system

The XS features a built-in autofocus system that is fixed to the sensor. It has a horizontal viewing angle of 60° and can sharply focus as close as 10 cm, either automatically or manually (via software). An integrated API function (is_Focus()) allows setting the focus automatic or manual.

Image sizes

The XS transfers live images in different sizes up to FullHD 1080p resolution (1920 x 1080 pixels) at 15 frames per sec. Using the powerful scaling functions, you can optimally represent the entire field of view even at low resolutions.

The CMOS sensor of the XS provides a resolution of 5 megapixels. The full image size is 2592 x 1944 pixels.

Digital zoom

The wide aperture angle of the XS captures a field of view that suits most applications. But you can also zoom in on a smaller area of interest by using the digital zoom (is_Zoom()) feature. This feature allows nearly continuously variable zooming with zoom factors from 1 to 4 depending on the current resolution.

Image controls

As opposed to the other uEye camera models, the XS carries out all automatic image controls (is_SetAutoParameter()) internally. This has the advantage that the auto white balance, auto exposure and auto gain (Auto ISO) functions respond very quickly.

With the optional auto contrast correction and backlight compensation functions, you can adjust the automatic controls in detail.

Color calculation

The camera's signal processor converts the sensor's raw data to a color format (is_SetColorMode()) in real time before transfer to the host computer. This helps to take load off the computer's CPU. The image data of the XS are transferred uncompressed in YCbCr format (2 bytes per pixel). If a different color format (e.g. RGB) is required, the uEye API can convert the data to the desired format.

The XS provides separate functions for setting the sharpness (is_Sharpness()) and color saturation (is_Saturation()).

In the Direct3D display mode, you can represent the camera's YCbCr color data directly with minimum CPU load.
