Abstract: An image processing method for facilitating data transmission is provided. An image compression method is performed to convert X-bits binary digital signals to a binary compressed data in the form of n*2m, in which n is represented by the former Y bits of the X-bits binary digital signals, m is set to the value of (X-Y), and represented by binary numbers with [log2 (X-Y+1)] bits. The binary compressed data is transmitted with a sequence of [log2 (X-Y+1)]+Y bits, representing (m, n), wherein m is the former [log2 (X-Y+1)] bits and n is the latter Y bits. Therefore, by the present image compression method, the transmission amount of image data is reduced. The transmission time of image data and the volume of a memory for storing the image data are also reduced.

In regard to an increasingly changeable color image, the present invention provides a deductive method in deciding upon a gray scale of the image to increase the color accuracy in amending an image.

Abstract: A method of providing the inputting units of the scanner with a foolproof function. Initially, while a specific inputting unit is activated, such as a push button being pushed, the connection between the operation of the scanner and other inputting units is terminated. This terminated connection is not regained until the specific action, which corresponds to the specific inputting unit, finishes. Moreover, an “activation” message can be directly displayed on the scanner while this specific inputting unit is activated, and while the scanner is processing some specific action, this action can be terminated with the function of the scanner and the connection between all inputting units regained as soon as this specific inputting unit is activated again. For any scanner with the foolproof function, while a specific inputting unit is activated, not only a corresponding specific action is performed but also the connection between the performing specific action and all inputting units is controlled.
