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 Pand Pare selected. Then an absolute value of the Pand the Pis 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 Pand Pseparately adjacent the image lines having level values Pand the Pare selected. An absolute value of the Pand the Pis calculated and the absolute value of the Pand the Pis compared to the value X. When the absolute value of the Pand the Pis smaller than X, then the image lines having level values Pand Pare determined as shading. However, when the absolute value of the Pand the Pis larger than X, then the image lines having level values P, P, Pand Pare determined as LBB.
