ABSTRACT:
An image display device preferably used for educational applications is disclosed. In the image display device, an instructor gives a lecture while seeing an original document without being disturbed by any element of the device. In addition, a video camera, which is detachably attached to the camera mount, may be tilted to the left or right or tilted upward or downward so that it is not required to move the original document when the left, right, upper or lower side of the document has to be picked up by the camera. The above display device also includes a means used as either a whiteboard or an OHP-filmed image revealing panel. The device thus improves educational effect when it is used for educational applications. The device is not expensive thus being widely used for educational applications without forcing excessive costs on the owner.
