摘要:
A dichromatic polarizing element comprising a water-soluble organic dichromatic dye selected from the group consisting of a bisazo compound of a specific structure, the tautomer thereof, and the salts of them, wherein the dichromatic dye comprises the aggregates thereof oriented to a definite direction such that the dye can polarize a light passed therethrough, and a method of producing the polarizing element orienting the aggregates by a specific method are provided.
摘要:
An image processing method of generating a color image by using a color palette table. The method includes a restriction step of restricting colors registerable in the palette table, on the basis of gamut data on an image output device which outputs the color image, a formation step of forming the color palette table on the basis of the color restriction obtained in the restriction step, and a generation step of generating the color image by using the colors registered in the color palette table.
摘要:
An improved previewing technique of displaying an image on a monitor prior to a printer printing the image. The image signal for driving the monitor is generated based on predetermined printer parameters. The printer parameters include the printer resolution (dots/inch) and/or the number of printable tonal levels or gradations, in addition to the printer color gamut.
摘要:
A multicolor printer which can print an image with improved image quality by selecting a desired color reproduction process depending on data to be handled. An output apparatus comprises an input unit 111 for receiving visual data containing data in a command format for output control; image data etc. delivered from an external apparatus; an analyzer 112 for analyzing the input data; a developing unit 113 for developing the input data into output data based on an analyzed result; a color processor 114 for executing color processing such as color space compression on the input data during the development by the developing unit; a color processing method storage 116 for storing a plurality of color processing methods executed by the color processor 114; and a selector 115 for selecting one of the plural color processing methods in the storage 116. When developing the input data by the developing unit 113 into the output data, desired one of the plural color processing methods is selectively used in the output apparatus depending on the input visual data. Thus, optimum color reproduction depending on any of plural types of input data attributes is enabled without increasing load on a host computer.
