Abstract: A method for recognizing abnormal image is disclosed. The invention utilizes level comparisons of adjacent image lines to determine if there is any abnormal image amid an image picture and whether the abnormal image belongs to shading or LBB. The method comprises the following steps. First of all, two adjacent image lines having level values Pi and Pi−1 are selected. Then an absolute value of the Pi and the Pi−1 is calculated. Next the absolute value is compared with a value X. When the absolute value is smaller than X, then the image lines are determined as normal. On the contrary, when the absolute value is larger than X, then at least one of the image lines is determined as abnormal. Moreover, another two image lines having level values Pi+1 and Pi−2 separately adjacent the image lines having level values Pi and the Pi−1 are selected.

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 a floating-point form of (1.n)* 2m. Bit m represents the first bit with logic level “1” of the X-bits binary digital signals, and n represents the bits taken from the X-bits binary digital signals after the bit m.

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.

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.
