1. A device for selectively displaying a magnified image, the device comprising:
- an image memory containing digital data representing at least a first image;
at least one main monitor, each monitor displaying a corresponding main image;
a main monitor memory associated with each main monitor, the main monitor memory containing digital data representing an image to be displayed on the corresponding main monitor;
a magnifier monitor which is movable with respect to each of the main monitors;
a magnifier memory containing digital data representing an image to be displayed on the magnifier monitor;
means for determining the position of the magnifier monitor;
a controller connected to the image memory, the magnifier memory and the position determining means, the controller causing, based on the position of the magnifier monitor, the magnifier memory to contain digital data representing a magnified portion of the image displayed on at least one of the main monitors, said data being obtained from the image memory, whereby a magnified image is displayed on the magnifier monitor.

Abstract
A method and device for selectively displaying a magnified image which permits an operator to appreciate the magnified image in its original context. The device includes a main monitor, a magnifier monitor, associated memories, and a controller. The magnifier monitor is movably mounted with respect to the main monitor. The position of the magnifier monitor in two dimensions represents the approximate center of a region on the main monitor to be magnified. The magnifier monitor is movable in a third dimension, and the position of the magnifier in the third dimension is used to determine the degree of magnification desired.

7. A device for selectively displaying a magnified portion of an image displayed on at least one main monitor, a digital representation of the displayed image being stored in a corresponding main monitor memory, the device comprising:
-
a magnifier monitor which is movable with respect to each of the main monitors; means for determining the position of the magnifier monitor; a magnifier memory containing digital data representing an image to be displayed on the magnifier monitor; and a magnifier controller connected to each of the main monitor memories, the magnifier memory, and the position determining means, the magnifier controller causing, based on the position of the magnifier monitor, the magnifier memory to contain digital data representing a magnified portion of the image displayed on at least one of the main monitors, said data being obtained from the corresponding main monitor memory, whereby a magnified image is displayed on the magnifier monitor. - View Dependent Claims (8, 9, 10)
