5.6 Crosshairs
5.6.1 Functionality
The crosshairs inserts a vertical and horizontal line into the image. The width of these lines is
one pixel. The grey level is defined by a 12 bit value (0 means black, 4095 means white). This
allows to set any grey level to get the maximum contrast depending on the acquired image.
The x/y position and the grey level can be set via the camera software. Figure Fig. 5.24 shows
two examples of the activated crosshairs with different grey values. One with white lines and
the other with black lines.
The 12-bit format of the grey level was chosen to be compatible with other
Photonfocus cameras.
Figure 5.24: Crosshairs Example with different grey values
Color camera models: in the debayered image, the color of the crosshairs where
Y is set to an even row number is not the same as the color of the crosshairs
where Y is set to an odd row number. Additionally there might be a slight dis-
tortion of the crosshairs due to debayering (demosaicing).
