摘要： In a matrix area, a plurality of linear areas each of which extends in a tilt direction tilted relatively to row and column directions are arranged in a direction perpendicular to the tilt direction without spaces, and the plurality of linear areas are alternatively assigned to first and second element groups along an arrangement direction. One element is specified in each element group and subsequently process of specifying an element farthest from specified elements, is repeated to acquire a turn-on order of dots with increase in gray level in one grayscale range and a turn-off order of dots with decrease in gray level in the remaining grayscale range, and a threshold value of each element is determined according to these orders. Thus, generated is a threshold matrix capable of reducing graininess in a halftone image with directionality in the tilt direction, and improving the reproduction of thin lines and characters.

摘要： An image recording apparatus has low intensity ink ejection parts for ejecting low intensity ink, and a high intensity ink ejection part for ejecting high intensity ink. With respect to a direction orthogonal to a moving direction of printing paper, a pitch of outlets in the high intensity ink ejection part is larger than that in the low intensity ink ejection part. Thus, manufacturing cost of the apparatus is reduced. With respect to each gray level in a middle grayscale range, if a tint image is recorded with the high intensity ink, a spatial frequency of this tint image is lower than that of a tint image recorded with the low intensity ink. By the above image recording control, even if the high intensity ink ejection part includes an abnormal outlet where a flight direction of droplet is abnormal, streak unevenness in a color halftone image can be suppressed.
摘要翻译：图像记录装置具有用于喷射低强度油墨的低强度喷墨部分和用于喷射高强度油墨的高强度喷墨部分。相对于与打印纸的移动方向正交的方向，高强度喷墨部中的出口的间距大于低强度喷墨部中的出口的间距。因此，装置的制造成本降低。对于中间灰度范围内的每个灰度级，如果用高强度墨水记录着色图像，则该色调图像的空间频率低于用低强度墨水记录的色调图像的空间频率。通过上述图像记录控制，即使高强度喷墨部分包括液滴的飞行方向异常的异常出口，也可以抑制彩色半色调图像中的条纹不均匀。

摘要： Each of moire elements which are repeat elements of first-order moire appearing by overlaying halftone images of first and second color components is positioned at one of candidate positions arranged at a moire pitch Pm in first and second moire directions orthogonal to each other. In a matrix area of a third color component, dot centers are arranged in a first tilt direction tilted relatively to the first moire direction by an angle of arctan((Pm)/(Pm)) and a second tilt direction orthogonal to the first tilt direction at a pitch of the square root of ((Pm2)+(Pm2)), and a threshold matrix of the color component is generated so that a halftone dot grows from each dot center in accordance with increase of gray level of the color component of the original image. Thus, it is possible to suppress second-order moire appearing in overlaying halftone images of the first to third color components.

摘要： A head in a printer has an outlet row including a plurality of outlets arranged in a width direction perpendicular to a scan direction. A threshold matrix is stored in a main body control part, and sleep elements representing sleep of ejection of ink are arranged in the threshold matrix at a regular interval in each element row which is a plurality of elements arranged in a row direction corresponding to the width direction. The threshold matrix is compared with a grayscale original image to generate data of a halftone image where during printing, the number of outlets included in each outlet group not brought into sleep state continuously in the width direction is made equal to or larger than 1 and equal to or smaller than a predetermined number. Thus, it is possible to easily suppress occurrence of unevenness in a printed image, caused by cross talk between outlets.

摘要： An ejection part (3) in an inkjet printer (1) has ejection mechanisms (31a to 31d) for ejecting fine droplets of colored ink and an ejection mechanism (32) for ejecting fine droplets of clear ink, and a colored image is formed on a colored image print area of print medium (9) by the ejection mechanisms (31a to 31d). By the ejection mechanism (32), the colored image on the print medium (9) is coated with the clear ink and a code image is formed on a blank area around the colored image print area. In the inkjet printer (1), since the coating of the colored image and the forming of the code image are performed with the same clear ink ejected from the one ejection mechanism (32), improvement of wear resistance and improvement of security of the colored image can be achieved while reducing manufacturing cost of the apparatus of the inkjet printer (1).

摘要： To generate a threshold matrix which is compared with an original image in creating a halftone dot image for each color component, in a matrix area for one color component, dot centers are arranged almost uniformly in a random fashion at a predetermined density and in a matrix area for another color component, dot centers are arranged almost uniformly in a random fashion at a density about 0.7 times the predetermined density. Then, threshold values are set so that dots should grow around the dot centers in accordance with an increase in gray level of the original image, to generate the threshold matrix for each color component. In creating the halftone dot images by using these threshold matrixes, characteristics of spatial frequency of the halftone dot images of these color components can be represented in a frequency space as areas (75K, 75C) in a shape of concentric rings. As a result, it is possible to create a multicolor halftone dot image with less graininess, with no portions approximate to each other in the characteristics of spatial frequency of these halftone dot images.

摘要： An operation part in a pattern inspection apparatus includes a defect candidate image generator for generating a binary defect candidate image representing a defect candidate area in an inspection image by comparing the inspection image with a reference image, in an inspection image masking part the inspection image is masked with the defect candidate image to obtain a masked inspection image. In a feature value calculation part, an autocorrelation feature value is obtained from the masked inspection image, and outputted to a classifying part. The classifying part comprises a classifier outputting a classification result on the basis of the autocorrelation feature value and a classifier construction part for constructing the classifier by learning. It is thereby possible to easily perform the high accurate classification of defect candidate using the autocorrelation feature value which is hard to characterize as compared with geometric feature value or feature value representing density.

摘要： In a threshold matrix generation part 3 implemented by a computer, a tint image in a specified gray level is generated from temporary lighting order set in a matrix area, and a smoothing operation is performed on the tint image, to generate a grayscale evaluation image. The lighting order is modified by changing ordinal numbers in the lighting order of respective positions included in specified areas in the matrix area which correspond to areas around boundaries of halftone dot areas in the tint image on the basis of values of corresponding pixels in the evaluation image. With this operation, when the smoothing operation is performed on a tint image in the specified gray level generated in accordance with a modified lighting order, a variation among values of pixels included in the specified areas becomes smaller than a variation among values of pixels included in the specified areas in a case where the smoothing operation is performed on the tint image in the specified gray level generated in accordance with an unmodified lighting order. Then, threshold values are determined in the matrix area with reflecting the modified lighting order, to generate the threshold matrix which is possible to suppress graininess in a generated halftone dot image.
