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.

摘要： According to a method and apparatus for estimating a halftone image, a unit area is set and shifted by a focusing lens and a photoelectric transducer in a binary image consisting of black and white regions, and the halftone image is estimated on the basis of a ratio of the white regions to the black regions within each unit area. The number of white pixels is counted by an A/D converter. When different unit areas are used, a specific one satisfying predetermined conditions is selected and shifted in the binary image, and prestored image data is read out from RAMs by column and row address generators and calculated to obtain a halftone estimated value within each unit area. The binary image can be thus a Bayer dither image or a digital binary image.
