In one aspect, the present disclosure provides a printer including a controller that controls a printing unit, the controller executing: a movement distance measuring process that measures a movement distance of the printing unit relative to a printing medium; a coordinate recording process that calculates a plurality of coordinates on the basis of the movement distance measured in the movement distance measuring process; a printing region setting process that sets a printing region on the basis of the plurality of the coordinates recorded in a memory in the coordinate recording process; and a printing image selection process that identifies an image that has the largest area from at least one image, the at least one image being extracted from a group of images pre-recorded in the storage unit by designating such images that fit within the printing region set by the printing region setting process.

An image reading device includes: an image reading unit configured to, in a process of reciprocating relative to a fixed document, read a document image using one or a plurality of reading colors, and when a plurality of reading colors are used, read the document image while successively switching the reading colors in a process of moving; a moving unit configured to move the image reading unit; a moving speed changing unit configured to change moving speeds of the image reading unit in an outgoing path and a return path based on a number “N” (where N is a positive integer) of the reading colors by the image reading unit; and a reading color number changing unit configured to change reading color numbers of the image reading unit in the outgoing path and the return path based on the number “N” of the reading colors.

To make it possible to suppress a delay of the start of rendering of a page even in the case where image data is included across the band boundary in the page of print data. The image processing apparatus of the present invention is an image processing apparatus that performs rendering by dividing a page into a first area and a second area based on print data and includes: a memory configured to store image data arranged across the first area and the second area; a first render configured to access the image data and to perform rendering by using pixels within the first area of all pixels of the image data; and a second render configured to access the image data and to perform rendering by using pixels within the second area of all pixels of the image data.

An image processing apparatus includes a processing unit that converts first input image data for a first region and second input image data for a second region to reduce a difference between first region recorded image density and second region recorded image density, and generates dot position data of a dot to be generated in each of the first and second regions based on the dot data after the conversion processing. The acquisition unit acquires edge information indicating a first object pixel edge of an image pixel for the first region and a second object pixel edge of an image pixel for the second region. Based on the acquired edge information, conversion and generation processing are performed in such a manner that a color signal of an edge pixel is increased/reduced to a degree lower than a degree to which a color signal of a non-edge object pixel is increased/reduced.

A method, non-transitory computer readable medium and apparatus for starting a multiple scanline error diffusion method are disclosed. For example, the method includes identifying a pixel for each scanline of a plurality of scanlines, wherein the pixel that is identified in the each scanline of the plurality of scanlines is offset, setting all pixels behind the pixel for the each scanline of the plurality of scanlines that is identified with a white pixel value and starting the multiple scanline error diffusion method

Disclosed is an image processing apparatus including: a derivation unit configured to derive a target luminance characteristic based on a viewing condition of an image and a print luminance characteristic predicted based a reflection characteristic corresponding to data thereon; a unit configured to generate print image data on an image by converting input image data by using a tone conversion characteristic that is set based on these characteristics, in which the derivation unit derives, in a case where a reproduction range of an illumination intensity in the print luminance characteristic is different, the target luminance characteristic so that a liner area of an output luminance in a case where the reproduction range is relatively large becomes large.

In a case where a setting that is a target of a first control is set in a print setting, the first control is performed, whereas in a case where the setting that is the target of the first control is not set in the print setting, the first control is not performed. The first control is performed to change an orientation of a drawing data such that the drawing data is printed on a sheet in an orientation with a bottom side and a top side of the drawing data respectively corresponding to a downstream side and an upstream side of the sheet in a conveyance direction of conveying the sheet to a printing apparatus that performs print processing to print the drawing data.

An image processing apparatus includes a processor configured to: acquire a read image of a document that is read by a document reading apparatus; and control an image output device such that the read image and an additional image are outputted to a medium with a significance portion and the additional image prevented from overlapping, and a length of the medium in a sub scanning direction is increased in a case where the significance portion of the read image and a specified region of the read image to which the additional image is decided to be added overlap.

An information processing system includes a service providing system and an apparatus that mutually communicate via a network. The service providing system includes a processing method storage configured to register a processing method in association with identification information of output data; and a first communicator that transmits, to the apparatus, the output data to which the identification information is appended. The apparatus includes an outputter that outputs the output data received from the service providing system together with the identification information; an inputter that accepts input of input data based on the output data output by the outputter; and a second communicator that transmits, to the service providing system, the input data input by the inputter, to which the identification information is appended. The service providing system performs a process on the input data by the processing method associated with the identification information appended to the input data.

A chart includes a plurality of area images. Each area image of the plurality of area images includes a figure. The figure indicates positional information of each area image of the plurality of area images in the chart. An image forming apparatus includes an image forming device configured to form an image on a sheet to create the chart, and an image reading device configured to read the image in the chart.
