摘要： Upon outputting halftone image data to an output device, density transformation is prevalently performed to improve image quality. Density transformation corresponds to linear gamma correction, and cannot correct for color fog and the like that may occur in a photo image. Hence, lightness and color-difference information of halftone image data is acquired on the basis of low-frequency components of frequency data obtained by transforming halftone image data into spatial frequency components, and a lightness and color-difference transform amount of the halftone image data is set on the basis of the acquired lightness and color-difference information.

摘要： Image processing apparatus and image processing method for formation of high quality image by high-speed error diffusion processing by execution of more complicated threshold condition processing in a simple manner. When error diffusion processing is performed on multivalued image data having plural density components and the result of processing is outputted, upon execution of error diffusion processing on a first density component among the plural density components, a threshold value used in the error diffusion processing is determined based on a density value of a second density component, then the error diffusion processing is performed on the first density component based on the determined threshold value, and the result of execution of the error diffusion processing is outputted. Further, upon execution of the error diffusion processing on the second density component among the plural density components, a threshold value used in the error diffusion processing is determined based on a density value of the first density component, then the error diffusion processing is performed on the second density component based on the determined threshold value, and the result of the error diffusion processing is outputted.

摘要： An optical fiber, which has a zero-material dispersion wavelength equal to or greater than 2 μm, and a high nonlinear susceptibility χ3 equal to or greater than 1×10−12 esu, and uses tellurite glass having sufficient thermal stability for processing into a low loss fiber, employs a PCF structure or HF structure having strong confinement into a core region. This enables light to propagate at a low loss. The size and geometry of air holes formed in the core region, and the spacing between adjacent air holes make it possible to control the zero dispersion wavelength within an optical telecommunication window (1.2-1.7 μm), and to achieve large nonlinearity with a nonlinear coefficient γ equal to or greater than 500 W−1 km−1.

摘要： An object of this invention is to prevent an increase in energy applied to a heating element and prolong the service life of a printhead even when the temperature of the printing element having a negative temperature coefficient rises and the resistance of the heating element decreases upon controlling a switching element for controlling a current flowing through the heating element so as to make energy as constant as possible. For this purpose, a printhead having a plurality of heating elements connected to a common power supply comprises: a switching element which is series-connected to the heating element and controls driving of the heating element at a voltage applied to a control terminal; a constant voltage source using a common power supply as a reference; a wiring resistance generated at a connection wiring line serial-connected to the heating element; and a voltage control circuit which controls to make the potential difference between both ends of the wiring resistance equal to the voltage of the constant voltage source when driving the heating element. Then, a current flowing through the heating element is made constant without any influence of the temperature of the heating element.

摘要： An image forming method comprises a step of reacting an ink containing a coloring material with a liquid composition containing fine particles reactive to the coloring material on a recording medium, where the reaction between the coloring material and the fine particles occurs in a liquid, the coloring material is adsorbed on the surfaces of the fine particles while keeping the monomolecular state as in the ink, and the fine particles having the coloring material on the surface aggregate each other. This method can provide images of high optical density and high color saturation, with less occurrence of white stripes in the image.

摘要： An image processing method is used to converting a color within a first color reproduction range that is a device-independent color space into a color within a second color reproduction range that is a color reproduction range of an output device. The image processing method includes defining, within the first color reproduction range, a third color reproduction range of a color that is estimated to be input; defining, within the second color reproduction range, a fourth color reproduction range that is smaller than the second color reproduction range; and, in performing the color conversion, compressing a color within the third color reproduction range into a color within the fourth color reproduction range and compressing a color within the first color reproduction range and outside the third color reproduction range into a color within the second color reproduction range and outside the fourth color reproduction range.
