Video Autofocus option The Video Autofocus option permits you to select and automatically focus on an object in the ROI (region of interest, measuring field) in the image of the surgical field. The video autofocus is based on the evaluation of the video image contrast: During focusing of the microscope's Varioskop optics, the video autofocus option continuously determines the video image contrast in the selected ROI. In this way, the video autofocus controls the microscope's Varioskop optics and adjusts it to the point of maximum contrast, corresponding to the point of maximum image definition. Autofocus menu The Autofocus menu offers you the following functions for selection: –

"ROI, on/off", activating / deactivating the ROI display

–

"ROI Size, smal/medium/large", selecting the ROI size

–

"ROI Position", branching to the AF - ROI Position submenu to define the ROI position

–

"Brake Automatic, on/off", activating / deactivating the automatic start of the focusing process

–

"Camera Position, left/right", entering the orientation of the external video camera.

–

"Advanced Settings", branching to the Advanced Settings submenu to enter the technical data of the external video camera.

Notes: – The functions "Camera Position left/right" and "Advanced Settings" are only offered for selection if your system is equipped with an external video camera. If you have an integrated video camera, these fields remain blank. –

As long as you are entering any settings in the Autofocus menu or its submenus, the ROI is displayed as a square frame in the video image on the monitor. A few seconds after your last action, the frame disappears from the screen.

Menu item "ROI, on/off" The position and size of the ROI are displayed on the video monitor in the form of a square frame. Use the "ROI on/off" function to activate or deactivate this display on the video monitor.

Use arrow keys ( , ) to move from Brightness to White Balance Lightmeter OSD Reset To Standards OK. In the following, the functions and the adjusting possibilities of the individual selection fields are explained. Gain When you open the Video Settings menu, the Gain setting is active. Use arrow keys ( , ) to adjust the brightness of the video image as required on the slider displayed. Using arrow key ( ) you can jump from GAIN to the Brightness selection field. Brightness In the Brightness menu, you can manually adjust the brightness of the video image (GAIN) or have the brightness automatically controlled. Automatic mode (Auto): (Standard setting for most applications) Allowance is automatically made for changing light conditions and the brightness level set on the GAIN control is adjusted accordingly. This ensures that the image brightness is always constant. This function is particularly suitable for situations with varying illumination intensities. Manual (Manu): Image brightness is adjusted to the brightness set on the GAIN control. If a bright or strongly reflecting instrument is used in the surgical field, the instrument will produce glare. The remainder of the image is still clearly visible at the brightness level set on the GAIN control. White Balance Activate the White Balance selection to perform the white balance procedure for the video image. The system adjusts the video signal in such a way that white areas in the surgical field are also white in the video image. To achieve this, place a suitable white object (e.g. a piece of white paper with a matte surface) under the microscope and focus the microscope on it, using a medium brightness level.

Integral (standard): The exposure is measured and averaged across the full video image. This metering pattern is recommended when the surgical field is evenly and fully illuminated.

–

Large: The exposure is measured in a field in the image center. This metering pattern is ideal for working with an eclipsed surgical field edge (resulting from a reduced illuminated field diameter).

–

Small: The exposure is measured in a very small field in the image center. This metering pattern is suitable for work in narrow channels when a very small illuminated field diameter is being used.

Press the ENTER key to change between the metering patterns.
