ABSTRACT:
The compact document imager and display apparatus has a two-dimensional image sensor array, a flat panel display such as a liquid crystal display (LCD), and processing electronics. An illumination source can be added to illuminate the document on the sensor array and to provide backlight for the LCD. Color imaging may be achieved by providing three sequential illumination pulses of appropriate colors. A document is placed in close contact with the sensor array. The document is illuminated and an electronic image is captured and stored in the processing electronics. The captured image can be displayed on the LCD by the processing electronics. The document, such as a single sheet of paper or a transparency, can be illuminated by the room light to perform image capture. The compact document imager can be used as a facsimile machines by providing telephone connections. Documents can be scanned using the sensor array and sent to other devices. Documents can be received from other sources and displayed on the LCD. A light-pen can be used to generate handwritten documents or highlight portions of documents. An X-ray imaging device is created by placing a thin phosphor sheet in contact with the sensor array. The x-ray imaging device is placed over an object illuminated by X-rays and the image produced by the glowing phosphorous is stored and displayed by the LCD.
