摘要： A colored image reading apparatus in which the light-intensity signals produced in response to the red, green and blue color components of the light carrying the image information pickup up from a given document sheet bearing multi-colored images are converted into quantity-of-ink data signals indicating the quantities of cyanic-, magenta- and yellow-colored inks to be used for the formation of colored pixels, wherein the conversion of the color-density signals into the quantity-of-ink data signals is effected by a conversion table into which are stored quantity-of-ink data produced through mathematic calculation involving logarithmic conversion of variable values which are generated as the products of multiplication between a set of fixed parameters and numerical values respectively representing the color densities indicated by the light-intensity signals. The set of parameters is selected from among a plurality of sets of parameters including optional sets of parameters and a standard set of parameters. Any of the plurality of optional sets of parameters may be selected either manually by the operator or through preliminary detection of the predominant color used in the original multi-color images. The standard set of paremeters is selected for use when none of the optional sets of parameters is selected. The color image reading apparatus of the present invention permits naturally colored images to be reproduced accurately.

摘要： A pictorial image comprising pixels represented by a combination of density values in respect to first color components (R, G, B) is transformed to a pictorial image comprising pixels represented by combination of density values in respect to second color components (C, M, Y). In accordance with the first color modification method, an operation expressed as Q=.alpha.P+.beta. is implemented to an original density value P using two correction coefficients .alpha. and .beta. determined in advance to determine a density value Q after transformation. In addition, in accordance with the second color modification method, density values after transformation are determined by the calculation of the k-th degree masking equation using the k-th degree masking coefficients. At this time, a color cube is defined with respect to the first color components. The color cube thus defined is divided into an n number of blocks. The k-th degree masking coefficients are defined every respective blocks. Then, calculation of the k-th degree masking equation is performed using the k-th degree masking coefficients defined with respect to blocks involving points indicative of original density values within the color cube.

摘要： A color recording method allows digital color recording by calculating fractional areas to be covered by each color used in recording. A plurality of sets of area factors for the colors are calculated from a plurality of sets of color equations corresponding to a plurality of sets of magnitude relationships between the area factors. One set of area factors having the same magnitude relationships as the set of magnitude relationships corresponding to the set of color equations from which the one set of area factors was calculated is selected for color image production. The colors can consist, for example, of three subtractive primary colors or of black and two subtractive primary colors, in different superposition combinations. A color recording apparatus has a camera, a processor, a memory and a printer. Reflectivities of inks of different colors are measured and substituted in the color equations. An optimum color image is produced, compensated for differences between input and output system characteristics.

摘要： An ink-jet color printing apparatus is comprised of a rotary drum that bears the paper or other medium to receive the color printing and rotates in a primary scanning direction. A group of yellow ink-jet heads, a group of magenta ink-jet heads, a group of cyan ink-jet heads and a group of black ink-jet heads are provided, with each group of ink-jet heads arranged in the secondary scanning direction parallel to the axis of rotation of the drum. These ink-jet heads form simultaneously dot lines of four different colors. Groups of ink-jet heads of respective color are comprised of a plurality of ink-jet heads arranged in the primary scanning direction so as to form a plurality of dot lines constituting a single scanning line. A single picture element is formed by a dot matrix having n.times.m possible positions on a plurality of dot lines. Intermediate colors and color densities thereof can be achieved by combinations of several kinds of colored inks and dot patterns formed on a single matrix.

摘要： An image processing apparatus includes circuitry to receive visible image data obtained by reading of a subject with a sensor having sensitivity to visible light in a visible wavelength range and invisible image data obtained by reading of the subject with a sensor having sensitivity to invisible light in an invisible wavelength range. The circuitry generates image data for displaying, in a designated color, a portion of the visible image data corresponding to a designated region of the invisible image data. The designated region has an absorption rate equal to or higher than a predetermined absorption rate.

摘要： A method implements image background removal. The method includes receiving an image and processing the image using a first color distance threshold to generate a first alpha mask. The method further includes processing the first alpha mask using a cartesian edge threshold and a second color distance threshold to generate a second alpha mask. The method further includes presenting the image combined with the second alpha mask in a combined image.

摘要： Image data expressed in a first color space is converted into an expression in a second color space to be used during rendering by using a color conversion profile, and converted image data is generated. A setting related to an application to physically-based rendering is performed on a parameter to be used when performing physically-based rendering on a print medium as a 3D object and related to an appearance of the print medium, the physically-based rendering of a printed print medium on which an input image is printed is performed using the set parameter, and a rendering image corresponding to an appearance of the print medium in a virtual space is displayed in a mode in which a difference in applications of the parameter during rendering is comparable.
