摘要： In a printer, threshold matrixes are prepared so that, in a color halftone image generated with the threshold matrixes, cell centers are arranged randomly, a direction where intervals of cell centers for cyan are maximum and a direction where intervals of cell centers for magenta are maximum are different, and the both directions are tilted relatively to a column direction corresponding to a scan direction of a head. A check pattern is recorded with the threshold matrix for each color component by the head, print densities in positions in a width direction of the check pattern, which corresponds to an arrangement direction of outlets in the head, are measured to acquire modification coefficients and then pixel values of an original image are modified by using the modification coefficients. This makes it possible to print a color halftone image with less graininess, without causing a beat pattern and streak unevenness.

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： A plurality of types of basic tiles are arranged in a matrix area while prohibiting an arrangement of only ON or OFF elements in two rows and two columns, to acquire an element matrix representing an arrangement of dots in a gray level of 50%. After one element is specified in each of a set of the ON elements and a set of the OFF elements, a process of specifying an element farthest from specified elements is repeated to acquire a turn-on order of dots with increase in gray level on a highlight side and a turn-off order of dots with decrease in gray level on a shadow side, and a threshold value of each element is determined in accordance with these orders. With this operation, it is possible to generate a threshold matrix which is capable of reducing graininess in an image generated by halftoning an original image.

摘要： Whether or not a luminance signal or an HD input signal is input to a picture signal recording apparatus is detected, and a recording mode is determined according to the detection of the luminance signal in a recording mode determining unit. In cases where the luminance signal is detected, first and second color difference signals of the HD input signal are alternately deleted on every scanning line. Thereafter, the luminance signal pertaining to odd-numbered scanning lines and the first color difference signal are time-compressed and multiplexed on every scanning line, and the luminance signal pertaining to even-numbered scanning lines and the second color difference signal are time-compressed and multiplexed on every scanning line. In contrast, in cases where the luminance signal is not detected, a luminance signal and first and second color difference signals of a normal picture signal input to the apparatus are time-compressed and multiplexed on every scanning line. Thereafter, the signals multiplexed are recorded on a magnetic tape according to the recording mode. Therefore, even though the number of scanning lines in the HD input signal is higher than that in the normal picture signal, the first and second color signals can be recorded within a limited frequency band.

摘要： The low and high occupancy rate matrix sets are stored in the inkjet printer which performs printing with dots having different sizes. For the original image where banding unevenness easily appears, used is the low occupancy rate matrix set where the occupancy rate of all dots is lower than 100% in the maximum value of gray level and the proportion of the large dots is high in a high range of gray level. For the original image where reproducibility of details is required, used is the high occupancy rate matrix set where the occupancy rate of all dots becomes 100% in a value of gray level lower than the maximum value of gray level and the proportion of the small dots is high in a middle range of gray level. It is therefore possible to perform appropriate printing in accordance with the classification of the original image.

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.
