Abstract: A liquid crystal display device includes: a TFT substrate including a TFT, an organic passivation film formed to cover the TFT, and an alignment film; and a counter substrate including a spacer and an alignment film. The TFT substrate and the counter substrate are bonded with a sealing material in a seal portion, with a liquid crystal interposed between the two substrates. A wall-like structure is formed in the seal portion of the counter substrate, in a direction parallel to a side of the counter substrate. A concave portion of the organic passivation film is formed at a position corresponding to the wall-like structure of the TFT substrate, in a direction parallel to the side of the TFT substrate. With this structure, a gap between the wall-like structure and the TFT substrate is increased to facilitate the movement of the sealing material before curing, to form the sealing material uniformly.

Abstract: Because the ejection state of a printing element in a printing apparatus may vary at all times, an inspection item for inspecting a printed image may be set in consideration of the ejection state of the printing element. An inspection item for inspecting a printed image may be set based on information including a temperature characteristic of a printing head and a state of ink such as an elapsed time from the last ejection. This allows image inspection that matches with variations in the ejection state of the printing element.

Abstract: In the present invention, a first calculation unit calculates, based on image data obtained by reading with a reading unit a plurality of patches formed on a printing medium by a plurality of nozzle regions constituting nozzle array of a printing head, respective color specification values of a plurality of correction regions corresponding to a plurality of nozzle regions constituting the nozzle array. Then, a target value setting unit sets, based on the calculated color specification values of the plurality of correction regions, a target color specification value of the patch. Further, a second calculation unit calculates a difference between each of the color specification values of the plurality of correction regions and the target color specification value as a correction amount. After that, based on the correction amount calculated, image data corresponding to an image printed by each of the plurality of nozzle regions are corrected.

This current control allows a control circuit to be made compact, and a motor with effective field means can be provided.

Abstract: When printing an image using a plurality of inks, color unevenness caused by variations in ejection characteristics among nozzles is corrected at suitable timings in accordance with change in the color unevenness over time, and favorable image output without noticeably color unevenness is maintained. For this purpose, parameters are prepared, for colors formed by combinations of at least two colors of ink, the parameters being determined so as to reduce differences in coloration on a print medium caused by individual variations in the ejection characteristics of a plurality of nozzles. When printing, a first color signal included in individual pixels is corrected for a second color signal by using the parameters. Information regarding the ejection volume characteristics of a plurality of nozzles is acquired as appropriate, and by estimating changes in coloration from this information, suitable timings for overwriting such parameters are determined.

Abstract: Provided are an image processing apparatus and an image processing method capable of reducing color unevenness due to variations in ejection characteristics among a plurality of nozzles when printing an image using a plurality of inks. To that end, a first image which is made up a color with noticeable color unevenness and similar colors is printed onto a print medium. The user then specifies a color and a nozzle position where color unevenness has occurred. On the basis of these results, parameters are set for a correction table referenced by an MCS processor. In so doing, it becomes possible to address the factor causing the color unevenness, and mitigate the effects of color unevenness in a focused way without incurring increases in processor load, memory requirements, or processing time as compared to the case of calibrating all lattice points.

Abstract: As viewed for each processing unit in head shading (HS) processing, a processing unit width is more than one pixel, so that a threshold arrangement corresponding to a target quality of an image intended by a dither matrix is kept while a possibility of avoiding zero dots from being generated can be enhanced. Moreover, the threshold arrangement is kept while a possibility of generating the same number of dots in processing units can be enhanced. Consequently, the threshold arrangement corresponding to a predetermined target quality of an image intended by a dither matrix is kept while it is possible to reduce occurrence of uneven density caused by the HS processing. Thus, it is possible to prevent the threshold arrangement from being limited by the HS processing according to the degree of the reduction.

Abstract: When an input image is shifted by 640 pixels from a test pattern with reference to the position of a nozzle, the remainder is obtained by dividing 640 pixels by pixels of the dither matrix in an x direction. For example, when the size of the dither matrix in the x direction is 256 pixels, the dither matrix is shifted by 128 pixels in a direction reverse to the x direction. In this manner, the phase of the dither matrix at the time of the quantization during test pattern printing matches the phase of the dither matrix at the time of the quantization during input image printing. Consequently, unevenness of the dither matrix at a position N becomes the same in both of the test pattern and the input image. The HS correction to density unevenness caused by the unevenness of the dither matrix becomes suitable for the input image.

Abstract: In a motor, a stationary member is provided with a number M (M is a positive integer) of first poles within 360 electrical degrees at spaces therebetween. A plurality of windings are at least partly wound in the spaces, respectively. A movable member is movably arranged relative to the stationary member and provided with a number K (K is a positive integer) of second poles. The number K of second poles is different from the number M of first poles. A unidirectional current supply unit supplies a unidirectional current to at least one of the windings so as to create an attractive force between at least one of the first poles and a corresponding at least one of the second poles to thereby move the movable member relative to the stationary member.

Abstract: Provided is an image processor and image processing method that are capable of suppressing both density unevenness and graininess that occur due to deviation of the printing position of dots that are printed by a plurality of relative movements (or a plurality of printing element groups). In order to accomplish this, the dot overlap rate of an image characteristic in which density unevenness stands out is made higher than the dot overlap rate of an image characteristic in which other defects stand out more than the density unevenness. By doing so, it is possible to suitably adjust the dot overlap rate according to an image characteristic, and to output an image having no density unevenness or graininess.

Abstract: An AC motor is provided. In the AC motor, there are M pieces (M is an integer of 3 or more) of stator pole groups SPG are arranged in a rotor axis direction, where each of the stator poles groups is composed of a plurality of stator poles which are for the same phase and arranged in a circumferential direction of the motor. Between the stator pole groups SPG, “M?1” pieces of annular windings WR are arranged which allow one-way current to flow therethrough. The windings WR are arranged such that the directions of current passing therethrough are reversed in turn in the rotor axis direction. The stator pole groups SPG are excited to generate magnetic fluxes ?G directed in a one way. The excited directions of the magnetic fluxes ?G are reversed in turn in the rotor axis direction.

Abstract: In low-resolution processing (reduction processing) in which input image data is separated into character print data and image print data to generate print data of lower resolution than that of the input image data, if a plurality of pixels is simply reduction-processed to one pixel, color of a color image surrounding a character may change. In an image processing method, calculation for performing reduction processing so that the plurality of pixels in the input image data corresponds to one pixel in the print data is performed as follows. A ratio of using a pixel value of a character attribute pixel in the calculation is set to 0, or set smaller than a ratio of using a pixel value of an image attribute pixel. As a result, a change in the color of the color image surrounding the character can be prevented.

Abstract: There is provided an image processing method in which in a full line type inkjet printer using a connecting head having an overlap region, even if a conveyance direction of a print medium is more or less inclined, a density change or degradation of graininess is not introduced. Therefore, an image data in a non-overlap region is distributed to a plurality of nozzle arrays such that ink is ejected from all the plurality of the nozzle arrays. On the other hand, a region where a print allowance rate changes in the overlap region is divided into plural regions, and the image data is distributed to the plurality of the nozzle arrays such that these regions are located to be shifted.

Abstract: An image processing apparatus and an image processing method are provided which, when forming an image using a plurality of different inks, can produce a satisfactory image free from problematical levels of density unevenness, graininess and insufficient density with any of these inks. To this end, when printing on pixel areas of a print medium by a plurality of relative movements between the printing unit and the print medium, the dot overlap rate of an ink that tends to show density unevenness is set higher than that of an ink that tends to show other image impairments more conspicuously than the density unevenness. This results in a good image that eliminates such image impairments as density unevenness, graininess and density insufficiency in the entire color gamut.
