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： An image processing apparatus which can produce improved quality copies by taking into account the effects which normally occur when successive copies of copies are made. When a document is to be copied, image information is input to a processing device relating to certain parameters associated with the image characteristics such as, for example, the toner density, thickness of the image information, type of copier used, amount of toner available at the time of copying, etc. This image information is then stored on the document copy in the form of a bar code which will change as successive copies of copies are made in such a way that the image quality of the copies is not degraded. The image information contained on the document via the bar code is combined with new input image information supplied by an operator, whereby the two sets of information are combined in a central processing unit in order to determine the necessary amount of correction processing required to compensate for the fact that the image has been reproduced a number of times whereby copies are made from previous copies. In this manner, the original document quality can be maintained.

摘要： An image processing apparatus for joining a shadow to, masking, or otherwise processing a color image. When an original color image is processed to have a shadow or to be masked, for example, the processed image is adequately colored. A shadow whose color components are consistent with those of an original color image is formed in a predetermined direction. An image produced by masking is also consistent in color with an original color image. Such mask processing and shadow processing may even be executed in combination without any contradiction in color.

摘要： An image-processing device applies a predetermined process to input image data so as to output the processed image data. The image-processing device comprises a medium-density detection unit, an expansion unit, and a non-character edge judgment unit. The medium-density detection unit detects a medium-density field of an image represented by the image data. The expansion unit applies an expansion process to the medium-density field detected by the medium-density detection unit. The non-character edge judgment unit judges the medium-density field applied with the expansion process by the expansion unit as a non-character edge field of the image represented by the image data.
