5.8 Image Turn Mode

Picking up a complete vertical (portrait) document or A4 page has

always been a critical issue because the image was 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 "Image turn" mode solves this prob-

lem.

Just place your document (or other vertical object) on the working

surface horizontally. Zoom in on it completely, so that approx. 90%

of the pixels of the built-in camera are used to pick up the docu-

ment. Press the IMAGE TURN key (#22). The SCB-12 turns the

picture electronically at an angle at 90º and outputs it correctly with

a much higher resolution than in normal mode. The left and right

margins are blackened out.

up the image sharpness will be increased.
