Abstract: In an image processing apparatus a controller acquires target image data representing an image including first and second type of objects. The controller specifies, as a specific type color material, one of first and second type of color materials whose remaining amount is smaller than that of the other, and determines a first reduction index value indicating a first degree of reduction in an amount of the specific type color material for printing the first type of object. The controller creates processed data by performing a reduction process on the target image data to reduce an amount of the specific type of color material for printing the first type of object on the basis of the first reduction index value. An amount of the specific type color material for printing the second type object is not reduced on the basis of the first reduction index value.

Abstract: A method includes generating color correspondence information correlating L number of first reference color specification values in a first color space with L number of determined second color specification values in a second color space on a one-to-one basis. The L number of determined second color specification values includes (L?Q) number of unmodified second reference color specification values, (Q?N) number of modified second reference color specification values modified in a first modification process but not in the second modification process, and N number of remodified second reference color specification values which are modified in both the first modification process and the second modification process, where L is an integer greater than or equal to two, Q is an integer greater than or equal to one and smaller than or equal to L, and N is an integer greater than or equal to one and smaller than or equal to Q.

Abstract: An image processing apparatus includes a controller configured to perform: setting characteristic information including first characteristic information and second characteristic information; and converting a target image data using the characteristic information. The first and second characteristic information correlate input values with output values in a specific color space. The input values includes a specific input value within a specific range. The specific input value is correlated with a first specific output value by the first characteristic information, and is correlated with a second specific output value by the second characteristic information. The first specific output value indicates that a colorant consumption quantity for the specific input value is changed from an original colorant consumption quantity by a first colorant quantity.

Abstract: In a print data generation apparatus, a print data generation apparatus generates print data. The print data includes post-replacement data obtained by the color replacement on pre-replacement data. The post-replacement data includes a plurality of post-replacement pixel values. Each post-replacement pixel value includes a plurality of post-replacement color components.

Abstract: An image processing device includes: a component separating unit; a distribution modifying unit; and a component combining unit. The component separating unit separates an image, which is represented by image data obtained by imaging a scene, into component images for a plurality of color components. The distribution modifying unit sets one of the component images for a predetermined color component as a reference component image, sets at least one component image other than the reference component image as at least one non-reference component image, and modifies distribution of pixels for brightness levels in each non-reference component image based on distribution of pixels for brightness levels in the reference component image. The component combining unit combines together the reference component image and the at least one non-reference component image modified by the distribution modifying unit.

Abstract: If a profile ID data is attached to image data inputted from an application program, this means that profile conversion has been performed on the image data in the application program. Thus, the image data is directly sent to a printer without the profile conversion being performed on the image data in a printer driver. However, if a profile ID data is not attached to the inputted image data, this means that the profile conversion has not been performed on the image data in the application program. Thus, the profile conversion is performed on the image data in the printer driver as needed before the image data is sent to a printer.

Abstract: A tape printer is presented to improve the print quality of a border portion between print areas. Dots, which are smaller in area than dots printed in a previous print area, are printed after being shifted by &agr; (1.0 dot) in the X direction from dots printed in an overlap area. Accordingly, even if the dots are printed slightly out of position, high-density overlap portions, where dots overlap with each other, and/or paper surface-exposed portions, where dots are away from each other, are not produced greatly or distributed unevenly.

Abstract: An optical waveguide element includes an optical waveguide formed on a light-transmissive dielectric substrate and having a higher refractive index than the refraction index of the substrate, the optical waveguide including a region having an effective refractive index which varies nonlinearly in a direction in which a light wave is propagated through the optical waveguide. The light wave guided through the optical waveguide enters the region, in which the angles of incidence and reflection of the guided wave at the boundary between the region and the substrate is gradually reduced due to the variation in the effective refractive index. When the angles of incidence and reflection of the guided wave becomes smaller than a critical angle, the guided wave is emitted out of the waveguide.

The apparatus includes a first and a second writing/erasing head for writing and erasing information on the first and second storage layers, and a recording controller for activating one of the first and second writing/erasing heads to erase previous information already recorded on corresponding one of the first and second recording segments, while activating the other head to write first new information on the other of the first and second recording segments.
