5.2.2 Window Function
With the Window Function activated, only the surface that contains image information is used to control the camera sensitivity, this way the camera
adjustment and the image contrast is optimized even for very thin optics and short work distances.
Once the object to be observed is in the center of the image, as with very thin diameter endoscopes in which the outer edge of the image is black,
activate the window function pressing the Window button. The object will now be seen with the adequate lighting on the screen and the outer
margins of the image will appear proportionally brighter.
Contrary to the standard measuring where the average brightness is intergraded on the whole image, by selecting the Window function only the
central part of the image is evaluated for an average brightness, not taking into account the external margins.
When the Window function is activated, a light around the button turns on.
If the object to be observed is centered in the monitor screen, as when thin endoscopes are being used (<10mm) , and where
the edge of the image displayed is black, select the Window function by pressing the corresponding button.
