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.

Abstract: A method and apparatus for receiving document images including portions linked to one or more electronic addresses. The linked portion of the document is identified using a predetermined visual attribute, such as bold-face text, or delimiters to mark the portion. The document image is then transmitted using, e.g., existing apparatus for transmitting images, such as a facsimile machine. An electronic address associated with the identified portion of the document is also transmitted using existing techniques, such as by touch-tone telephone. The address may be a voice telephone number, facsimile telephone number, World Wide Web address, or any other address with which communication can be established. At the receiving end, both the document image and electronic address are received. Pattern matching is performed on the document image to identify the portion with the predetermined attribute as a linked portion. The received electronic address is then correlated with the linked portion. When the document image is displayed on, e.g., a computer screen, the linked portion is visually identified so that the recipient can access the electronic address by, e.g., clicking on the portion using a mouse. Communication may then be initiated by the recipient with the entity associated with the electronic address.

Abstract: An original reading apparatus which prevents lamp blackening includes a lamp for illuminating the original, and reading circuitry for reading an image formed on the illuminated original. Control circuitry is provided to apply to the lamp a first predetermined voltage after reading the image formed on the original has been completed, if a voltage applied to the lamp at the time of original image reading is lower than a second predetermined voltage. The first predetermined voltage is higher than the voltage applied to the lamp at the time of the original image reading.
