Abstract: There is provided a color conversion table having a plurality of pieces of reference color image data making correspondence between color data for a first image device and color data for a second image device and including a specified total information amount. The color conversion table is used to distribute the reference color image data over a prescribed area in a specified color space. Color data information for each reference color image data is increased more than a specified amount within a limit of the specified total information amount. Further, a color conversion table is created using an original table which highly accurately defines colors in part of the table. If such color conversion tables are referenced for color conversion, it is possible to suppress the storage capacity, provide color matching, and perform high accuracy color conversion.

Abstract: Bidirectional recording is carried out with a printer that enables variable size dots of different ink quantities to be created with different driving waveforms W1 and W2. Variables are set to a time delay n0 before output of the driving waveform W1 and a time interval n6 between the driving waveform W1 and the driving waveform W2. The output timings n0 and n6 of the driving waveforms W1 and W2 in the course of a backward pass of main scan are individually regulated on the basis of dots created in a forward pass of the main scan as a reference. This arrangement desirably reduces a positional misalignment of dots created in the forward pass with dots created in the backward pass with regard to each of the variable size dots having different ink quantities, thus ensuring high-quality printing.

Abstract: The image processing device of the invention generates dot data representing dot on-off state in respective pixels of an image and supplies the generated dot data to a printing device. The printing device creates multiple dots on a printing medium to print an image and is designed to print the image with at least a first ratio of a printing resolution in a main scanning direction to a printing resolution in a sub-scanning direction. The image processing device includes a halftoning module that applies one specified setting of a halftoning parameter, which corresponds to the first ratio, to a halftoning process to generate dot data from image data representing the image.

Abstract: The technique of the invention sequentially supplies dot data to multiple dot formation elements, which are actuated to create dots simultaneously on multiple pixel arrays arranged at preset intervals, and thereby completes a resulting output image on an output medium. The procedure temporarily stores received dot data in a memory, reads out only dot data of the multiple pixel arrays, on which dots are to be created simultaneously by the multiple dot formation elements, converts the read-out dot data into high-resolution dot data, and supplies the converted high-resolution dot data in an order of actual dot formation to the multiple dot formation elements. Dots are sequentially created according to the supplied high-resolution dot data to give a high-quality image. Only the dot data of the multiple pixel arrays, on which dots are to be created simultaneously by the multiple dot formation elements, are set to the current object of resolution enhancement.

Abstract: The method of the present invention generates print data to be supplied to a printing module, which ejects ink to form dots on a printing medium. This method includes a dot data generation step of generating dot data, which represent a dot formation in respective pixels, according to pixel values of given video data with regard to the respective pixels. The dot data generation step includes the step of generating the dot data, such that a dot formation with respect to at least part of the pixel values in a pixel belonging to an end area located on an end of the printing medium is different from the dot formation in a pixel belonging to a middle area located in a middle of the printing medium, so as to prevent adhesion of ink to the printing module.

In a liquid ejecting apparatus provided with a liquid ejecting section for ejecting liquid droplets of a plurality of sizes toward a medium, the liquid ejecting section ejects liquid droplets toward the medium, and the liquid droplets of the smallest size of the liquid droplets, among a plurality of sizes, are not included in the liquid droplets that are outside of and that do not land on the medium.

Abstract: An image processing device of the invention converts a resolution of input image data into a preset recording resolution and generates print data. In the image processing device of the invention, multiple halftoning process modules are provided corresponding to multiple different aspect ratios of recording resolutions as resolutions for image recording to respectively perform different halftoning processes according to the different aspect ratios. The image processing device sets one recording resolution among multiple recording resolutions, which include at least two different recording resolutions having an identical aspect ratio, and converts the resolution of the input image data according to the set recording resolution to generate multi-tone data representing tone values expressed in respective pixels of the image data.

Abstract: According to the present invention, for at least one specific type of ink drop from among a plurality of types of ink drops of different quantities of ink, dot data can be generated in such a way as to compensate for error of ink amount for each specific type of ink drop with reference to information representing error of ink amount for given specific type of ink drops. By means of this, even if there is deviation in error of ink amount for each of different types of ink drops, color can be reproduced more accurately.

Abstract: The image processing apparatus of the invention determines dot on-off state of respective pixels to create dots at a preset density corresponding to a tone value of image data and outputs data representing positions of dots to be created as control data to a printer. The printer creates dots according to the control data in synchronism with main scans and sub-scans of a print head to complete a printed image. The technique of the invention determines the dot on-off state according to the image data to have weighted dot distribution in a direction different from the scanning direction of the print head. Positional misalignment of dot formation generally occurs in the scanning direction of the print head. The weighted dot distribution in the direction different from the scanning direction of the print head thus does not significantly affect the resulting picture quality even in the event of some positional misalignment of dot formation and ensures a high-quality printed image.

Abstract: An image processing device of the invention processes images with threshold matrices in either of two available print modes, that is, a first print mode and a second print mode. When a combination of the printing resolutions of the second print mode in the main scanning direction and in the sub-scanning direction is identical with an interchanged combination of the printing resolutions of the first print mode in the main scanning direction and in the sub-scanning direction, a threshold matrix for the first print mode is rotated by 90 degrees to set a threshold matrix for the second print mode. When the printing resolutions of the second print mode in the main scanning direction and in the sub-scanning direction are respectively n times (where n denotes a positive number) of the printing resolutions of the first print mode in the main scanning direction and in the sub-scanning direction, on the other hand, a threshold matrix for the second print mode is used as a threshold matrix for the first print mode.
