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： 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.
