WolfVision VZ-9plu - Handbuch (Seite 12)

Picking up a complete vertical (portrait) document or A4 page has always been a critical
issue for a Visualizer because the image
s always picked up in a horizontal (landscape)
format.
The camera could only use 50% of its pixels to pick up a vertical (portrait) page.

on the working surface horizontally and
zoom in on it completely, so that approx. 90% of the pixels of the built-in camera are used to
pick up the document, then press the IMAGE TURN key (#35). The Visualizer turns the
picture electronically 90 and outputs it correctly with a much higher resolution than in
normal mode. The left and right margins will be black.

A computer can be connected to the External RGB input (#22) of the Visualizer.
By pressing the EXTERN-key (#31 or #46) you can switch between the Visualizer image
and the image of the external input to be displayed to the audience. The extern mode can
also be used for only one output, changeable in the on-screen menu (see page 14).
The Visualizer has a built-in A/D-converter in order to digitize the analog RGB signal from
the computer and output it on the RGB and DVI outputs in the selected signal format.
Prefered resolution is SXGA- (1280x960@60Hz).
Supported resolutions from VGA (640x480@60Hz) to 1080p (1920x1080@60Hz) with
several resolutions and refresh rates in this range.
Visualizers with serial number 1008068 and higher support VESA-DDC on the external
input.
