The character edge area determining unit (21) determines a character edge area in input image data.

The output image processing unit (12) performs an image process for a target pixel in the determined character edge area in order to adjust a toner consumption amount in accordance with the number of continuous edge pixels (i.e. continuous pixels that belong to the character edge area) included in a reference window of which a center is set on the target pixel and an average value of pixel values of the continuous edge pixels.

An image processing apparatus comprises an image processing device. The image processing device comprises a receiving port and a processor connected together. The receiving port receives old image data corresponding to a document image of a document. The processor divides the old image data into first area image data corresponding to a first area image of the document, and second area image data corresponding to a second area image of the document, and further performs image enhancement processing on the first area image data to obtain enhanced first area image data. Thus, the first area image may be separated from the second area image, and the image enhancement processing is performed on the first area image. The enhanced first area image data and the second area image data are separately outputted or combined for output. An image processing method for the image processing apparatus is also provided.

A binary image is generated from a multivalued image based on a threshold, an edge is extracted from the multivalued image, an edge image is generated by correcting a position of the extracted edge, and a synthetic binary image is generated by synthesizing the edge image and the binary image.

An image-processing apparatus generates data to be outputted to formation unit which form a shaped article on a recording medium. An acquisition unit acquire first shape data that represents a shape of unevenness. A first generation unit generates edge data that represents a shape of an edge of the unevenness, based on the first shape data. A second generation unit generates first recording amount data that represents a recording amount of a first recording material that is used to form at least a part of the edge in the edge data on the recording medium, or first dot arrangement data that represents dot arrangement of the first recording material on the recording medium, based on the edge data.

An inspection apparatus for detecting a difference between image data obtained by reading a sheet, and a reference image of the image data. The inspection apparatus obtains first image data by reading a sheet having a patch image printed thereon, obtains second image data from print data of the patch image, performs edge correction on a line included in the second image data by applying an edge correction parameter, and obtains an edge correction parameter that minimizes a difference between the density of the second image data subjected to the edge correction and the density of the first image data, and stores the obtained edge correction parameter.

An apparatus configured to generate image data represented in achromatic color from input image data and output the generated image data to a printer includes a controller. The controller is configured to replace color information of an object included in the input image data with an achromatic signal value, determine, based on an achromatic signal value corresponding to color information of a pixel of interest in the input image data, whether the pixel of interest satisfies a predetermined condition, and perform enhancement processing on the color information of the pixel of interest in a case where the pixel of interest is determined not to satisfy the predetermined condition.

Luminance data indicating luminance of the print product illuminated by the lighting is calculated and processing for causing a high luminance region to have gradation characteristics is performed.

Provided is a printing method for performing printing using a serial printer. In printing of a print image including a line image, the printing method includes a raster line forming step of forming each of raster lines configuring the image, by a plurality of pass operations. In the formation of each of the raster lines, when printing of a region corresponding to edge pixels of the line image by a first pass operation, which is one of the plurality of pass operations, is first printing, and printing of the region corresponding to the edge pixels by a second pass operation that is different from the first pass operation, of the plurality of pass operations, is second printing, a brightness of the printing by the second printing is higher than a brightness of the printing by the first printing.

An information processing apparatus includes a processor configured to: obtain plural images each including any of plural objects; and determine, based on an analysis result regarding the plural objects in the plural images, according to which of two or more objects, among the plural objects, included in an image the image is corrected.

An image processing apparatus includes one or more processors and one or more memories, the one or more memories including one or more programs. The one or more programs cause the one or more processors (a) to acquire first shape data that represents a three-dimensional shape of unevenness, (b) to generate edge data for specifying a first area that corresponds to an edge of a convex portion and a second area that does not correspond to the edge of the convex potion in the unevenness, based on the first shape data, and (c) to generate, based on the edge data, data to form the first area and not the second area on a recording medium.
