A multicolor printing process which uses original first and second print patterns for carrying out a print pattern modification process carries out a reduction process by which an overlapping portion of the patterns are reduced to obtain a reduced overlapping portion. A linkage portion is formed between the reduced overlapping portion and a residual portion of the first print pattern. A modified first print pattern is then formed which consists of the residual, linkage, and overlapping portions....

A method and apparatus converts from a color appearance space to a colorant space and determines quantities of colorants required to reproduce a color in a medium. A set of input color signals representing a desired or measured color in the color appearance color space is developed and compared to a set of calculated color signals, representing an estimate of the color in the color appearance space, to produce an error signal. A set of scan estimate signals representing color components are gene...

An image processing system that automatically optimizes the perceptual quality of images undergoing a series of selected image-processing operations. The automatic optimization capability allows the system to bypass expensive and time-consuming trial-and-error methods associated with interactive methods. The system consists of a set of image-processing operations, an architecture, and an intelligent control. These elements take into consideration profiles of sources from which the images are gen...

Recoloring an object may be performed by calculating an offset in the hue, saturation and luminance between the source and destination colors. The source image is then adjusted using these offsets to produce the desired color.

A color image outputting apparatus adapted to generate display image data for simulatively displaying on an image displaying apparatus a color image to be formed on a recording sheet by means of an image recording apparatus. The apparatus includes: a conversion table for converting color image data into first color image data which exclude any influences of a ground color of the recording sheet; and a ground color correction circuit for correcting the first color image data outputted from the co...

An image processing device which includes: an image data inputting unit that inputs image data; a converting unit that converts image data inputted by the image data inputting unit into data of channels in a predetermined color space; a ground detecting unit that detects respective ground levels from the data of each of the channels converted by the converting unit; a calculating unit that calculates a ground removing level for each of the channel, based on the ground level of each of the channe...

A limitation in the physical resolution of an image sensor offers a motivation to improve the resolution of an image. Super-resolution is mainly applied to gray scale images, and it has not been thoroughly investigated yet that a high resolution color image is reconstructed from an image sensor having a color filter array. An object of the invention is to directly reconstruct a high resolution color image from color mosaic obtained by an image sensor having a color filter array. A high resolutio...

An advanced cosmetic color analysis system analyzes the color of a three dimensional object to produce a plurality of color values for distinct subsets of a portion of the object, and a cosmetic analyzer combines the color values to produce a cosmetic color determination that has relative weightings of multiple cosmetic colors. Contemplated systems are particularly useful for determination of suitable cosmetic products (or composition thereof) to achieve a particular and desired cosmetic appeara...

A method and apparatus is provided for efficiently and automatically removing unwanted temporal lighting variations from image sequences. Specifically, temporal light variations from a sequence of images are removed by a process of selecting a reference image (R) and designating a portion of the reference image as a reference image region (M), designating a first portion of at least one base image (F) of the sequence of images as a first selected image region (M') and a second portion as a secon...

In order to correct for colors of images taken photographs of e.g., patient's skin in a clinical medicine, the method of the present invention comprises a color chart for image correction including a sheet base substrate, on the back surface of which an adhesive layer capable to adhere onto an object such as the patient's skin and color materials for example three colors R, G, B as three primary colors of lights applied on the surface to be captured in a color image with the object to correct fo...
