摘要： An original image comprises a printed region on which a predetermined printed matter is realized and a background region on which no printed matter is realized. The shape of a peripheral zone in the original image comprises the shape of the background region, which shape exists particularly at the peripheral region of said original image. It is determined whether or not the original image comprises the special document by detecting the peripheral zone. Further, the original image has an outer-frame region, having a predetermined shape, at the peripheral region of the original image. The determination is carried out using a result of measuring the width of the outer-frame region. Further, the width of the outer-frame region comprises a width along a direction substantially perpendicular to a direction extending along the outline of the original image.

摘要： Processing used to represent a gradation by changing the number of black pixels and the number of white pixels in a matrix of 8.times.8 pixels. First, edge information sampled from the input data is allocated to corresponding pixel positions of the output data with priority. A residual gradation value is determined by subtracting a value corresponding to the edge information already allocated from the average gradation of the input data, and black pixels and white pixels are alternately allocated to the remaining pixel positions of the output data except for the edge region, in accordance with the ratio of the number of those remaining pixels to the residual gradation value. When the region except for the edge region is divided into a plurality of regions, an average gradation for each of the divided regions is determined and a residual gradation value is distributed to each of the divided regions in accordance with the ratio between the average gradations, followed by allocating black pixels and white pixels to each of the divided regions in accordance with the ration of the distributed residual gradation value to the number of pixels in that region.

摘要： An image density control method for electrophotography which controls at least one of various image density parameters in response to values detected from different pattern areas. The image density parameters include an amount of charge deposited on a photoconductive element by a charger, bias voltage for development, toner density in a developer, amount of toner supply to a developing unit and transfer potential. At least two pattern areas having different potentials are formed on the surface of the photoconductive element by at least one of various means for forming charge patterns which include controlling the energization of the charger, controlling an illuminating lamp and projecting an image pattern. At each of the pattern areas, at least one of values associated with an image density is detected which include a surface potential of the pattern area before development, toner density of the pattern area after development, a surface potential of the pattern area after development and an image density of an area of a transferred image which corresponds to the pattern area. The value associated with an image density is compared with a predetermined value and matched with specific one of the pattern areas.

摘要： A digital color converting apparatus applicable to a color copier and others for converting only a desired color included in a color image into another desired color. One of a plurality of input image signals which has the highest level is identified to determine a color to be rendered by the instantaneous signals and, then, whether the result of the identification and a color specified are coincident is determined. Hence, color conversion is effected only in those regions in which the image is regarded as being of the color specified. For color conversion, the input image signal associated with an original color to be changed is applied to an output terminal which is assigned to an alternative color while, at the same time, the input image signal associated with the alternative color is applied to an output terminal which is assigned to the original color, i.e., signals individually associated with the original and alternative colors are replaced with each other.

摘要： An image density control method for an electrophotographic apparatus is disclosed which prepares a white pattern region and a black pattern region on a photoconductive element whose electrostatic latent images are far different from each other in potential. Values relating to image densities individually associated with the two pattern regions are sensed and, based on the sensed values, parameters relating to image processing which effect image density are controlled. When any of the sensed values does not lie in a predetermined range, it is suitably compensated.
