An image processing apparatus comprises a generation unit configured to generate, based on print data, pieces of information to be used for generating intermediate data based on the print data, and store the pieces of information in an external storage device connected to the image processing apparatus, and a rendering unit configured to generate the intermediate data using the pieces of information, and generate a raster image by performing rendering based on the generated intermediate data.

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.

An object of the present disclosure is to avoid degradation of image quality. An embodiment of the present invention is a printing apparatus including: a print head; a detection unit configured to detect an edge region and a non-edge region of an object in image data; and a tone correction unit configured to adjust an application amount of a printing agent for a unit region based on whether the unit region is the edge region or the non-edge region, in which the printing apparatus is capable of performing printing in a first printing mode or a second printing mode, in the first printing mode, an input resolution of the image data is lower than a printing resolution of the print head, in the second printing mode, the input resolution of the image data is higher than or equal to the printing resolution of the print head.

A recording control device that controls a recording device that discharges a dot to perform recording includes an edge detection unit configured to detect an edge of an image represented by image data, and a recording control unit configured to generate dot data specifying the dot based on the image data and to cause the recording device to perform recording based on the dot data. The recording control unit causes an internal region, located on an inner side of an edge region including the edge of the image, to be recorded using a dot having a smaller size than that of a dot used for recording of the edge region, or to be dot-off.

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.

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.
