摘要： In an image processing apparatus, first peak density pixels of one dimension each having a peak density in one-dimension direction larger than a predetermined density are detected from image data located in a predetermined image area of a document image, and second peak density pixels of two dimensions each having peak densities in two-dimension directions larger than the predetermined density are detected from the image data. Further, there are counted a number of the detected first peak density pixels of one dimension and a number of the detected second peak density pixels of two dimensions, and then, it is judged whether or not the image data located in the predetermined image area are image data of a dot photograph image, a photograph image or a character image based on the counted numbers.

摘要： Originals are fed onto a platen glass one by one by an automatic original feeder to be read out by a reading system. The originals are converted into digital image data. The image data is transferred to a memory unit. The memory unit is controlled by a CPU. The memory unit is configured of an image memory, a sentence direction recognizing portion, an RAM producing a management table, an original direction (top and bottom direction) recognizing portion, a rotation processing portion, a sign memory and the like. Based on top and bottom directions of original images and directions in which sentences run included in the images, arrangement of images in a 2in1 or 4in1 mode is determined.

摘要： An image processing apparatus capable of contracting or enlarging an original image includes a variable scale magnification processing unit for magnifying the original image in accordance with a magnification m, and a digital filter for correcting an image quality. Since weighting matrixes h1-h5 of the digital filter are varied depending on magnification m, a deterioration in image quality can be prevented irrespectively of magnifications.

摘要： In a method of joining image data divided into a plurality of parts each having an overlap region with the other at a border line portion into a single image for output, an image processing apparatus joins the plurality of partial images having overlap regions L at border line portions. The image processing apparatus extracts a joining line connecting pixels with small density difference between partial images from the overlap region, and joins the partial images with each other along the joining line. The image processing apparatus extracts a line connecting pixels with small density difference with adjacent pixels from the overlap region of the partial images as a joining line upon extracting the joining line. The density difference at the joining border is minimized in order to make the joining line look more natural, and make offset of images in the overlap region less recognizable.

摘要： An additional data useful for the management of copies of a document for an image forming apparatus is embedded in a hard copy of the document. The additional data is embedded in an inherent image of a document as discrete dots arranged in a prescribed format. Preferably, the size of each of said discrete dots is not so large as to be recognized easily with naked eyes. The additional data can be embedded in unit of blocks. Further, the density of the discrete dots is different from the density adjacent to the discrete dots. The image data for embedding an additional data can be obtained by reading a document, or by receiving data sent from a computer or read from a floppy disk. An additional data embedded in a hard copy can be extracted from the image data on the hard copy. Further, the production of a copy according to the image data can be controlled according to the extracted additional data. For example, if the additional data means that the source of the hard copy is a secret document, the copying is allowed only for a legitimate user. An additional data is generated for each copy according to the extracted additional data for embedding it in a hard copy to identify each copy. The additional data generated for each copy are compiled and they are used to manage copies of various sources systematically and illegal copies can be traced easily. If the additional data received from a printer is not consistent with the additional data already stored, the printing may be prohibited. A transmitter for transmitting an additional data may be provided in-a document such as a book.

摘要： An image processing apparatus capable of reducing a nonuniform pitch in the sub scanning direction of an image, caused such as by unstable paper feed of a printer, for example, is formed as described below. An adder adds the density value of one pixel of an input multi-valued image and a diffused error output from an error weighting filter. A comparator compares an output from the adder and a corresponding threshold of a variable threshold matrix, and outputs the result as a binary image. The variable threshold matrix is formed of two sub matrices with a size of 3×3 connected in a main scanning direction, and an average value of thresholds in one sub matrix is larger than another. Accordingly, a line component vertical to the main scanning direction is added in an output image. This line component masks a nonuniform pitch in the sub scanning direction.

摘要： In a dot image discrimination circuit, a dot image in an area composed of many multi-tone pixels including a central pixel is discriminated. A pixel (change point) at which the density of the image data is prominent in a first direction is detected in a plurality of pixels. Then, it is inspected if change points exist continuously in a second direction perpendicular to the first direction. The change points are counted in an area of a prescribed size around the central pixel, but some change points existing continuously in the second direction are not counted. Thus, a pixel in an image made of regular dots can be discriminated from a pixel in another type of image such as a character image. The discrimination of a dot image can be performed fast and precisely.

摘要： An input signal represented by values of many levels obtained by reading out an original image is applied to a pixel characteristic extracting unit for extraction of a characteristic of a pixel. Based on the extracted pixel characteristic, a gain calculating process is effected based on the pixel characteristic in a first gain calculating unit. An attribute flag showing an image characteristic extracted by the pixel characteristic extracting unit is added to the gain calculated error data which is stored. An area characteristic is determined in an area characteristic extracting unit based on the flag. Based on the determination result, error correction with high precision is carried out in a second gain calculating unit.
