发明名称 Image processing system having skew correcting means
摘要 An image processing system comprises a memory for storing an input image data in a bit map, a display coupled to the memory for displaying an image which is described by the input image data, an input device for inputting a point data for designating a straight line as a reference line in the image which is displayed on the display, a calculation part coupled to the input device for calculating an inclination angle of the reference line with respect to an axis of a rectangular coordinate of the bit map, and a rotation part coupled to the calculation part for rotating the input image data stored in the memory in the bit map so that the inclination angle becomes approximately zero.
