personal computer based image processing system, image processing, through a user interface of a scanner control

摘要

An image processing system (10) provides a user interface (27) over its scanner (22) for selecting one image processing program (86) to process image signals generated by the scanner (22). The image processing system (10) comprises a personal computer (14) and a scanner (22) connected together. The scanner (22) comprises a scanning circuit (50) for scanning a document to generate image signals, a user interface (27) having a display device (26) for displaying message signals and an input circuit (52) for generating selection signals according to user inputs. The computer (14) contains a plurality of image processing programs (86) for processing the image signals generated by the scanning circuit (50) and a scanner control program (82). The scanner control program (82) transmits a message signal which contains one instruction about selecting one of the image processing programs (86) to the scanner (22) and then activates one of the image processing programs (86) to process the image signals according to a selection signal received from the scanner (22) which is generated by a user according to the message signal displayed by the scanner control program (82).
