Description

computer image processing system

The present invention relates to an image processing system, in particular to a computer image processing system which utilizes a scanner user interface to control a program in a personal computer to automatically process image signals generated by the scanner.

In a personal computer, the operation of the scanner needs to be controlled by the scanner control program on the window interface. When scanning a document, the user must first drive the scanner control program on the window interface with the mouse and the cursor, and then the document can be input into the computer through the scanner and stored in the form of an image file. If the image file is to be processed again, the user needs to start another image processing program such as a character recognition program (OCR-optical character recognition) or a drawing program with a mouse and a cursor to process the image file again. This troublesome file input and processing mode is very inconvenient for the user. The use of the window interface and scanner control program is quite complicated and difficult for many people who are not familiar with computers. People who are familiar with computers will have to rely on the assistance of others to complete these tasks. And for the people who are familiar with computer use, if each file input all needs to repeatedly start each program on the window interface to complete the file input and processing work, then the work efficiency must not be very good.
