microprocessor 16 from a connected personal computer not shown during a presentation of this type the user may want to display additional or new documents that are not resident in the computer this flow chart shows how a document 26 can be scanned and displayed in the middle of a presentation from a connected personal computer to add a new document to a presentation which is being provided to the microprocessor 16 from a personal computer the user turns on the unit 46 and connects the personal computer 80 through the computer image input 84 digital images are then provided to the microprocessor 16 from the personal computer digital images from the personal computer 82 are then displayed when a new document is to be added to the presentation the user inserts 48 the first page of the document 26 to be scanned into the scanning paper path the user would then push 50 the scan button on the control panel 20 alternatively the signal from the document sensor 36 can be used to initiate the scan this commands the microprocessor to turn on the scanner unit feed motor which transports the document to the scan lamps and linear image sensor 52 the control microprocessor turns on 54 the scan lamps 30 and signals the linear image sensor to collect image information 56 the image information is processed 58 by the microprocessor 16 to adjust the color correction and to compress the digital image the compressed image is then stored 60 in the image memory 18 this sequence is repeated 62 until all pages of the document are scanned to display the images the user presses 64 a u201c next u201d play image button 66 on the control.
