摘要： An electrophotographic copying apparatus, which is able to classify an image in a copy area of the original. The electrophotographic copying apparatus estimates a copy area of an original within a scan area based on copy condition data set and stored through an operation unit. A sampler samples the scanned image data in the copy area to form image data. An identifying unit uses the image data thus obtained to identify an image classification of the copy area from a group of image patterns.
