Auto/Manual Focus

Auto Focus

The auto focus function is designed to focus on most types of subjects. In Auto Focus mode, the VIEWCAM automatically focuses on what- ever is in the centre of the scene. Always keep the subject in the centre of the screen.

Notes:

If no subject is in the centre of the screen, the focus area will expand and the subject nearest the centre will be focused on.

If no subject is displayed on the screen, the VIEWCAM will automatically zoom out until a subject comes into the frame.

Manual Focus

The Auto Focus may not be able to focus on the subject in the situations shown below. In such situations, set the VIEWCAM to Manual Focus mode and focus manually.

To cancel Manual Focus mode

Perform step 1 above, and press the D button to set the VIEWCAM to Auto Focus mode (“FOCUS”).

Notes:

The VIEWCAM may not be able to focus correctly if the subject is within approximately 1.5 m. Set the zoom control to wide angle, and then try refocusing.

If the lens is dirty or fogged, the VIEWCAM may not be able to correctly focus.

The Manual Focus mode will be cancelled if the power source is interrupted.
