Built-in Digital Scaler (for Extern-in and USB-Stick)

The Visualizer has a built-in digital image scaler which can process the signal from the external input and

output it in the same mode as the Visualizer image (For example: If the Visualizer is set to output an SXGA

image to the projector and the computer outputs an XGA signal, the scaler of the Visualizer converts the

XGA image of the computer to SXGA. As a result the projector does not readjust the input mode when

switching between the Visualizer and computer image).

In addition images on a connected USB-stick are automatically scaled to the current output mode of the

Visualizer.

The output resolution of the Visualizer can be changed in the on-screen menu (see page 16).

Integrated Seamless Switch

The Visualizer has an integrated Seamless Switch.

This allows for a seamless transition (fade-over/dissolve effect) when switching between the Visualizer

image, the image from the external input, the internal image memory of the Visualizer and images on an

USB-stick. This feature makes switching from one media to the other appear very smooth and professional.

The behavior of the Visualizer can be changed in the on-screen menu (see page 16).

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. WolfVision's

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 (#23). 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.

The Picture in Picture Mode offers the possibility to show two different

pictures at the same time on one screen. Just press

to activate the Picture in Picture mode. The

current picture (i.e. external signal, image memory) will be shown in the

lower left corner and the live image will be shown in the upper right corner.

The size of the live image is much bigger.

The content of the live image can be changed i.e. by recalling a stored

image memory.

Following comparisons are possible: Extern-In, image memory, live

image. The content from the small image is frozen, except when the signal

from the Extern-In is shown.
