摘要： Methods for designing and producing a security feature are provided. In general, the present disclosure provides methods of designing a printed image in a security feature, the security feature comprising an array of optical elements overlaying the printed image, wherein the printed image comprises a two dimensional matrix of rows and columns of pixels, the method comprising; correcting for a mismatch between the pixels of the printed image and the array of optical elements by doing one or more of: adding one or more pixels; removing one or more pixels; and moving one or more pixels.

摘要： Techniques for reducing or eliminating image banding in an ink-jet image are provided. In an example, a method of operating a printer to reduce or eliminate image banding can include generating command profile for printing a given image, applying a filter to the command profile to provide a filtered profile, and dispensing ink from a printhead of the printer based on the filtered profile. In certain examples, the filter can randomize droplet sizes of ink dispensed while executing the printing to reduce or eliminate image banding.

摘要： An image processing apparatus includes a processor configured to: acquire image information obtained by an image reading apparatus including an illumination unit having an uneven balance in an amount of light in a sub-scanning direction; and specify a position of a folding line in a sheet from the acquired image information. The acquiring by the processor includes acquiring first image information obtained by reading the sheet in a first state in which the folding line in the sheet is positioned in a direction intersecting the sub-scanning direction of the image reading apparatus, and second image information obtained by reading the sheet in a second state in which the sheet is directed to an opposite side to a side in the first state. The specifying by the processor includes specifying the position of the folding line in the sheet based on the first image information and the second image information.

摘要： An image inspection device detects an abnormality of a formed image by comparing imaged data obtained by imaging the formed image with original image data of the formed image. The image inspection device includes a hardware processor that: adjusts the original image data to reduce sharpness of the original image data; and detects the abnormality by comparing the adjusted original image data with the obtained imaged data. The hardware processor partly restricts the reduction of the sharpness.

摘要： A method of optimizing printing is applied to a printing apparatus and has following steps of retrieving an input image, executing a tagging process on the input image for tagging one of an edge tag, a fuzzy tag, and a photo tag on each sub-image of the input image, executing the different printing converting process on each sub-image according to its tag for obtaining a printable image, and printing according to the printable image. The present disclosed example can deepen the object edges in the image being printed, improving the image quality of non-edge regions, and improving the printing quality.

摘要： An image processing unit detects an edge portion of an input image and outputs first data for correcting the detected edge portion. The image processing unit also detects a thin line in the input image and outputs second data for correcting the detected thin line. In a case where a pixel of interest is subjected to both correction processes using the first data and the second data, a greater correction amount is selected and the correction is made using the selected correction amount, and a result corrected image is output as an output image.

摘要： The present invention discloses a false color removal method comprising: receiving a current pixel including a first color value, a second color value and a third color value, in which the three color values are composed of a maximum value, a medium value and a minimum value; performing permutation to the maximum value, the medium value and the minimum value to obtain six permutation results; calculating six weighting values, in which a kth weighting value is calculated according to at least a kth permutation result of the six permutation results and the three color values, and the k stands for an integer-variable between one and six; calculating six products, in which a kth product is obtained by multiplying the kth weighting value by the kth permutation result; and using the sum of the six products to update the first, second and third color values.
