A control method for an information processing apparatus that displays an edit screen of print data for printing a predetermined page, comprising: displaying, on the edit screen, a print region that includes a binding position indicating a position at which binding is performed using a binding material in the predetermined page and indicates a printable region in the predetermined page; receiving designation of a layout position of an image in the predetermined page; and making a notification if the designation is received so that the image is laid out in a predetermined region including at least a partial region in the print region between the binding position and a side of the print region on a side of the binding position, wherein a printing apparatus executes printing based on the print data edited in the edit screen.

A method for generating ejection position data indicating an ejection position where ink is ejected includes performing an edge detection process, an edge correction process, and an ejection position data generation process based on processing target data indicating an image to be printed. In the processing target data, a non-ejection value indicating that ink is not ejected to a corresponding ejection position or an ejection value other than the non-ejection value is set as a pixel value of a pixel. In the edge detection process, a position where a pixel to which the non-ejection value is set and a pixel for which the ejection value is set are adjacent is detected to detect an edge. In the edge correction process, the pixel value of the corresponding pixel is changed to a non-ejection value for at least a part of the ejection position where ink is ejected to draw the edge.

An image processing device includes: a first matching circuit to determine whether an image matrix of image data of a first resolution matches a first pattern, and output a first determination result; a first converting circuit to, if the image matrix matches the first pattern, replace a target pixel of the image matrix with a first pixel pattern of a second resolution, and output first image data of the second resolution; a second converting circuit to convert the image data of the first resolution into image data of the second resolution, and output second image data of the second resolution; a detecting circuit to detect whether the target pixel is included in a fine line structure, and output a detection result; and a selecting circuit to output one of the first image data and the second image data based on the first determination result and the detection result.

A method for improving the print quality of graphic elements, in particular vectorized letter graphics, in PDF documents in the prepress stage of a printing process by using a computer, includes analyzing the page content of the PDF document by using the computer and saving the page content in a suitable data structure, searching the data structure for graphic elements, in particular letter graphics, that fulfill specific predefined criteria relating to an evaluation of the height and width of the graphic paths of graphic elements that are present in the PDF document, by using the computer, converting the selected graphic elements into image masks by rendering the selected graphic elements on the computer and substituting the generated image masks for the originally selected graphic elements in the PDF document by using the computer. The PDF document with the generated image masks are printed on a printing machine.

An image processing device includes circuitry to segment an image corresponding to input image data into a black text area including black text and a non-black text area of the image data other than the black text area, perform a first type of color correction on pixel data items in the black text area and a second type of color correction on pixel data items in the non-black text area to generate a processed image, and determine whether or not the image is a color image using the processed image. The second type of color correction is different from the first type of color correction.

A white-plate graphic erosion process is performed on print data subjected to a RIP process in the following procedure. First, an erosion candidate region which is a candidate for a region in which a white-plate graphic is eroded is determined. Then, a region to be applied with an ink of a color other than white is determined. Then, an application target region is determined. Then, a region other than a region obtained by an erosion process out of the application target region is determined to be an erosion allowed region. Then, a region included in the colored region and the erosion allowed region out of the erosion candidate region is determined to be an erosion target region. Finally, the values of data of pixels included in the erosion target region among white-plate data are rewritten such that the amount of white ink applied to the pixels is reduced.

In a case where another first region exists which faces the edge pixel across a second region on a line in a predetermined direction passing through the edge pixel of the first region, the correcting unit selects a correction amount for correcting the exposure amount applied by the exposing unit for the pixel to be corrected from information describing a plurality of correction amounts in accordance with a first number of pixels being a number of pixels on the line within the second region between the first region and the other first region and corrects the exposure amount for the pixel to be corrected in accordance with the selected correction amount.

In a case where another first region exists which faces the edge pixel across a second region on a line in a predetermined direction passing through the edge pixel of the first region, the correcting unit selects a correction amount for correcting the exposure amount applied by the exposing unit for the pixel to be corrected from information describing a plurality of correction amounts in accordance with a first number of pixels being a number of pixels on the line within the second region between the first region and the other first region and corrects the exposure amount for the pixel to be corrected in accordance with the selected correction amount.

A computing system including a processing circuit in communication with a camera having a field of view. The processing circuit obtains image information based on the objects in the field of view and defines a minimum viable region for a target open corner. Potential minimum viable regions are defined by identifying candidate edges of an object and determining potential intersection points based on the candidate edges. The minimum viable region may then be identified and validated from the potential minimum viable regions.
