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： A color processor for reproducing a color image from color image signals. The processor has a scanner or a generator to obtain color image signals, an A/D converter to generate digital image signals from the color image signal, a density converter to generate density signals from the digital image signals, a controller to control the density converter, and an image reproducer to reproduce a color image according to the density signals. The density converter has a plural conversion data in a ROM memory. Color balance, density control, and picture/character mode change are all performed by selecting data from the conversion data and using the data for the density conversion.

摘要： In an image forming machine, density data of small pixels in an objective pixel determined according to density of pixels adjoining the objective pixels, the objective pixel determines a recording position for each color based on density distribution of the adjoining pixels when the recording position of each color is modulated in the primary scanning direction and secondary scanning direction based on density distribution of both the objective pixel and the adjoining pixels. Further, there are provided an image discriminator for image judgment on the objective pixel and a modulator for modulating a recording position using a reference wave with a long cycle when an image is judged to be a halftone image area under a reference wave with a short cycle when an image is judged to be a character image area.

摘要： In a method of forming an image in a form of pixels, the density distribution around a target pixel is obtained by processing image signals of pixels neighboring the target pixel. The target pixel is sub-divided into a plurality of sub-pixels which form of matrix of n rows.times.m columns. The sub density distribution of the sub-pixels in the target pixel is assumed from the density distribution of the neighboring pixels. The density of each of sub-pixels is determined by multiplying the density of the target pixel, by a constant P and a density ratio of the corresponding sub-pixels in the sub density distribution.
