This tab provides parameters for setting the hotpixel correction and test image function for your uEye
camera.

· Hotpixel
Hot pixel are sensor pixels whose brightness value deviates significantly from the brightness value
of the surrounding pixels in the case of long exposure times or a high gain setting. Basically every
sensor has a small number of hot pixels. CCD sensors have less hot pixels than CMOS sensors,
which is due to the different sensor systems. The hot pixels are detected during uEye camera
testing and written to a coordinate list in the camera. If hotpixel correction is enabled, the
correction function eliminates these pixels before debayering.
§ Mark hotpixel
If you select this check box, the hot pixel positions stored in the camera are graphically
represented in the image.
§ Hotpixel correction
Select this check box if you want to enable a software-based hotpixel correction.
· Test image
The camera transmits a selectable test image that you can use for testing the data transmission.
You can choose from different types of test images, depending on the camera type.
§ Selection
Some of the test images (e.g. Black image and White image) are created by the sensor and are
available in both, USB-based and GigE-baseduEye models.
With all GigE uEye HE cameras (CMOS and CCD sensors) you can also choose moving and
stationary test images that are created by the camera hardware (e.g. Colored wedge, Animated
line, Coldpixel/Hotpixel grid).
