摘要： The current methods and systems for correcting image information improve input and output characteristics. Although .gamma. correction curves have been used in prior art, the current invention allows more refined control in the correction process without additional parameters or hardware. The refined control includes adjustments at a localized area of the correction curve, an efficient conversion between a standard range value and a device-dependent value, a color-specific correction and a flexible user interface. Furthermore, the above described advantages are provided on demand rather than storing the pre-calculated information.

摘要： An image synthesizing system is provided which uses an intermediate transfer belt on which a plurality of toner images are superimposed. The image synthesizing system is used for an image processing apparatus which forms a toner image on a recording sheet by using an electro-photographic method. The image synthesizing system comprises a photosensitive drum on which the toner image is formed and an intermediate transfer belt which makes contact with the photosensitive drum so that the toner image formed on the photosensitive drum is transferred onto the intermediate transfer belt. A plurality of toner images are formed on the intermediate transfer belt, each of the toner images being formed on the photosensitive drum in accordance with image data obtained from different image data sources, the toner images being transferred onto the intermediate transfer belt one after another. A command ejection mode can be set by an operator in which an additional image will be superimposed on a first superimposed image. In the command ejection mode, the image generation will be begun by a print command and an ejection command will terminate the command ejection mode. Both the print and ejection command are inputted by an operator via a control panel.

摘要： A digital image processing method and an apparatus for the same which separate an original image into a plurality of color components to thereby produce image data each being associated with a respective one of the color components. The image data are individually processed to provide record color component density data. One halftone representation pattern is specified on a color component basis by the record color component density data to record that pattern. In color-by-color halftone data processing, there are used halftone representation patterns which are different in the positions of tone rendering spots from one color to another. Each of the record density data is extracted by assigning a particular area of the pattern thereto. The halftone representation patterns adapted to record a first and a second color which degrade color reproducibility when mixed together, e.g., those for magenta and cyan are provided with the centers of the above-mentioned spots at different positions from each other. The halftone representation patterns for recording a third color such as yellow have spots the centers of which are distributed between those of the patterns adapted for the first and second colors. The methodology and apparatus provide for the suppressing of overlapping of colors in a low density range despite the use of the same density pattern by changing the pattern phase, color by color and in addition implementing variable magnification recording of a high quality color image by use of a submatrix type recording system.

摘要： A mother matrix pattern as a fixed matrix pattern is specified with gradation data, and information in an area of the specified mother matrix pattern in accordance with the instructed magnification is extracted as information of a child matrix pattern so as to obtain image information with the child matrix pattern being allocated to the gradation data. Plural types of mother matrix patterns are prepared and one of them is specified in accordance with the instructed magnification. For example, at small instructed magnifications, the mother matrix pattern having recording (display) dots dispersed as widely as possible over the entire pattern is specified and used for conversion of the gradation data, while at larger instructed magnifications, the type of the mother matrix pattern is specified to match characteristics of the image.

摘要： A mother matrix pattern MMP is divided into (m.times.n) child matrix patterns CMP.sub.11 -CMP.sub.mn comprising m patterns in the main scanning direction and n patterns in the sub-scanning direction, where the first foot-character denotes the position of each child matrix pattern within the mother matrix pattern in the main scanning direction and the latter foot-character denotes the position thereof in the sub-scanning direction, the mother matrix pattern being expressed by; ##EQU1## and image information corresponding to one mother matrix pattern is obtained with (m.times.n) gradation data ##EQU2## comprising ICD.sub.11 -ICD.sub.mn similarly, information of the child matrix pattern CMP.sub.ij in the mother matrix pattern specified with the gradation data ICD.sub.ij is obtained as information in the form of bit distribution for the gradation data ICD.sub.ij. In other words, the position of each of the child matrix patterns for obtaining image information in accordance with both array of one mother matrix pattern and (m.times.n) gradation data is located in a position corresponding to the position of the gradation data within the mother matrix pattern. The reproduced image is thus formed in such a fashion that (m.times.n) child matrix patterns having information of the respective mother matrix patterns in accordance with the respective gradation data and locating in predetermined positions to constitute one mother matrix pattern are arrayed in an area of the reproduced image corresponding to one mother matrix pattern.
