A print engine is adapted to print image data from a plurality of pre-processing systems that supply image data at different image resolutions and halftoning states. A data interface receives the image data and associated metadata including an image resolution parameter and a halftone state parameter. A metadata interpreter interprets the metadata and determines image processing operations that are required to prepare the image data for printing using a printer module. A resolution modification processor module processes the image data to modify its resolution if the metadata interpreter determines that the image resolution of the image data does not match the printer resolution. A halftone processor module processes the image data by applying a halftoning operation if the metadata interpreter determines that the image data is not in an appropriate halftoning state.

An image processing apparatus includes an acquisition unit acquiring content larger in size than a screen and scrolled on the screen as a moving image, an extraction unit extracting, from the moving image, a plurality of frame images corresponding to a plurality of divided images obtained by division of the content based on a size of the screen, and a generation unit generating a single still image by synthesizing the plurality of frame images extracted by the extraction unit.

Provided is an image forming apparatus including an image formation unit, a character size decision unit, a generation unit, and a replacement unit. The image formation unit forms an image on paper. The character size decision unit decides a size of a character included in a second text image, based on an image including a photographic image and a first text image. The generation unit generates a descriptive sentence of the photographic image. The replacement unit replaces the photographic image with the second text image. The second text image indicates a text image corresponding to the descriptive sentence.

An image forming apparatus includes: an image processor configured to perform first image processing on image data having a first resolution and to add tag data to a target pixel where second image processing is to be performed; a resolution converter configured to convert the image data into image data having a second resolution higher than the first resolution, and to perform the second image processing based on arrangement of the image data having the first resolution and the tag data; a pulse generator configured to generate an on-off modulation signal and an application-current switching signal in accordance with the image data having undergone the second image processing; and a light source driver configured to drive the light source in accordance with a current setting value output from an application current setter depending on the application-current switching signal and the on-off modulation signal.

In a case where a tile image drawing instruction is included in a Graphics Device Interface (GDI) drawing instruction output from a GDI application, there is a difference between a result of drawing the drawing instruction with a GDI printer driver and a result of drawing the drawing instruction with a V4 printer driver in some cases. In a case where an application of an output source of an XML Paper Specification (XPS) drawing instruction is a GDI application and a tile image drawing instruction is included in the XPS drawing instruction, the aspect of the embodiments performs modification of the tile image drawing instruction so that resolution of a tile image with which pattern drawing is performed in accordance with the tile image drawing instruction is changed.

A print engine is adapted to print image data from a plurality of pre-processing systems that supply image data at different image resolutions and halftoning states. A data interface receives the image data and associated metadata including an image resolution parameter and a halftone state parameter. A metadata interpreter interprets the metadata and determines image processing operations that are required to prepare the image data for printing using a printer module. A resolution modification processor module processes the image data to modify its resolution if the metadata interpreter determines that the image resolution of the image data does not match the printer resolution. A halftone processor module processes the image data by applying a halftoning operation if the metadata interpreter determines that the image data is not in an appropriate halftoning state.

An image processing device which generates a halftone image includes: an image size adjustment unit which adjusts a size of the input image; and a halftone processing unit which performs halftone processing on the input image size-adjusted to generate a halftone image, wherein: the image size adjustment unit adjusts the input image to a same size in two or more printing modes among the plurality of printing modes, and the input image of the same size is subjected to the halftone processing; the unit limits arrangement of dots constituting the halftone image to dot arrangeable places of a selected printing mode among the plurality of printing modes, and performs the halftone processing based on an error diffusion method using an error diffusion coefficient matrix according to the selected printing mode; and the functions performed by the image size adjustment unit and the halftone processing unit are achieved using a computer.

A printing device includes: a set unit on which a print medium can be set; a projection unit (projector) capable of projecting a first image onto the print medium set on the set unit; a printing unit capable of printing a second image on the print medium set on the set unit; and a control unit configured to modify a printing specification of the second image to be formed on the print medium based on modification information regarding a modification made to a projection specification of the first image projected onto the print medium by the projection unit.
