摘要： A number of character string determination sections determine whether a pixel of interest corresponds to a character or a line drawing. The character string determination sections use mutually different determination methods. A character determination selector section selects a determination result output from the character determination section that uses a determination method most suited to a background sensing result obtained by a background sensing section. In this manner, either the character or the line drawing can be determined using an efficient method in accordance with the background state of a color image.

摘要： In an image processing section, a foam toner signal generator generates a foam toner signal corresponding to a foam toner amount to be transferred to a three-dimensional print designation region discriminated at a three-dimensional print region discriminator, and a foam toner interpolation signal generator generates a foam toner interpolation signal corresponding to a foam toner amount to be transferred to an image region equal to or greater than a constant area in an ordinary print region discriminated at the three-dimensional print region discriminator. Foam toner of a predetermined amount corresponding to the foam toner signal is transferred to the three-dimensional print region, and foam toner of an amount that is less (of a lower height) than the predetermined amount and corresponds to the foam toner interpolation signal is transferred to the ordinary print region.

摘要： A method and apparatus for selectively applying image enhancement processing to parts of an image. In one embodiment, spatial processing transformations, such as sharpening for example, are reduced or bypassed for pixels having color code values within a range known to be adversely affected by the spatial processing transformations. In another embodiment, color correction processing transformations are bypassed for pixels having color code values within a neutral color range. These neutral colors may have a gray-correction transformation applied in order to better separate the neutral colors from the other colors. According to another embodiment, color code values for pixels are transformed to two or more different color spaces. If a color correction transformation will have adverse affects on a pixel in one color space, corrected data from a different color space can be utilized for the pixel.

摘要： In a color image processor for converting a RGB input image data into a CMYK image output data, it is determined whether a data format of the input image data is a non-picture image format or a picture image format. For the input image data of the non-picture image format, a color conversion is performed with values of C, M and Y colors made minimum and a value of K color made maximum, when values of all of the R, G and B colors are minimum, and, for the input image data of the picture image format, a color conversion is performed with the values of the C, M and Y colors set to temporary values slightly smaller than the maximum values thereof when values of all of the R, G and B colors are minimum. Final C, M, Y and K colors are obtained by performing the Black-Generation and Under-Color-Removal processing for the temporary values.

摘要： The technique of the present invention carries out color conversion of first image data expressed by a first color system into second image data expressed by a second color system. The procedure first collects multiple adjoining pixels of the first image data into one block, and calculates a tone difference of the first image data in the block based on the first image data of the respective pixels. When the calculated tone difference is less than a preset value, procedure carries out collective color conversion without discrimination of the respective pixels included in the block. This enables the high-speed color conversion. When the calculated tone difference is not less than the preset value, on the other hand, the procedure carries out color conversion by a unit of each pixel included in the block. This prevents deterioration of the picture quality. The technique of the invention thus ensures the high-speed color conversion without deteriorating the picture quality.

摘要： An interface section analyzes print data including data for identifying an object or data showing the setting of color processing and others and sets required color processing in units of a printed page. According to the set color processing, a color processing section sets corresponding color correction table and halftoning processing table in a high speed random access memory for example. The interface supplies a drawing instruction together with attribute data corresponding to the setting in the color processing section to a drawing section. The drawing section plots image data composed of color data every dot according to the drawing instruction and stores the drawing instruction together with the attribute data every dot in an image memory. The color processing section executes optimum or intended color processing for color data in the image memory, referring to a color correction table and a halftoning processing table respectively corresponding to its attribute data and generates image reproduction data. Accordingly, arbitrary color processing can be realized by a controller composed of light hardware.
