An information processing device includes an information acquisition unit that acquires at least one of attribute information of image data to be image processed and setting information related to the image process on the image data, and a prediction unit that predicts, based on a machine-learned model that accepts input of at least one of the attribute information and the setting information to output a period required for the image process, a period required for the image process on the image data from information acquired by the information acquisition unit.

An image forming apparatus includes a controller. The controller generates page images of one or more pages by performing image processing on acquired input image data. The controller determines a job generation method to be either a first method or a second method. The job generation method is a method through which print job data is generated. The first method is a method through which the print job data is generated based on page image data indicating a page image of one page among the one or more pages upon completing the image processing on the page image of the one page. The second method is a method through which the print job data is generated based on the page image data of all pages included in the output image after completing the image processing on the page images of all the pages included in the output image.

Image processing apparatuses, methods and storage mediums for use with same are provided herein. In at least one embodiment, an image processing apparatus makes a setting to use a storing unit as a decompression buffer and a compression buffer based on drawing data including compressed image data, and makes a setting not to use the storing unit as a decompression buffer but to use the storing unit as a compression buffer based on drawing data not including compressed image data.

An image processing method of performing rasterization of a page in units of band area includes, among other things, performing, in units of band areas, rasterization based on second intermediate data stored in a first memory area for storing intermediate data and compressed raster data stored in a second memory area. The rasterization of the plurality of band areas is performed in parallel. In addition, the performing of the rasterization based on the second intermediate data and the compressed raster data includes selectively decompressing, in units of predetermined areas, a piece of the compressed raster data stored in the second memory area, in accordance with which band areas, of a plurality of band areas, are to be subject to the rasterization.

Disclosed is an image processing apparatus, including a receiver that receives a setting of a job; a reader that optically reads an original; a memory that stores the image data; and a hardware processor that instructs the external device to store the image data to be edited, and edits the image data page by page by using the page edit function of the external device, wherein when a temporary storing job for temporarily storing the image data in the memory is executed, the hardware processor judges whether a setting of a setting item for an edit of the image data page by page is changed, and in case that the setting of the setting item is changed, the hardware processor carries out a preceding transmission process in which the image data stored in the memory is transmitted to the external device and is stored in the external device.

An image data processing method includes: allocating a storage region for at least one of a plurality of planes including a first color plane, a second color plane, and a third color plane configured for respective colors of three primary colors; dividing into a plurality of image regions having identical regions that mutually correspond between the plurality of planes; analyzing a variable indicating an identicalness of images in the image regions that correspond between the plurality of planes to determine the identicalness; and executing a sharing process between the plurality of planes based on the determined identicalness so as to generate image data representing an image constituted of the plurality of planes.

The invention includes an arrangement determiner that determines an arrangement of a plurality of images, a rendering processor that performs rendering on the plurality of images in accordance with a result of detection processing for detecting an off line, on which none of the images are present across a target range in a second direction perpendicular to a first direction in which a print medium is transported, in the target range including the plurality of images arranged in accordance with a determination performed by the arrangement determiner, and a halftone processor that performs halftone processing on the images on which the rendering has been performed and outputs to the printing apparatus the images on which the halftone processing has been performed.

An image data processing method includes: allocating a storage region for at least one of a plurality of planes including a first color plane, a second color plane, and a third color plane configured for respective colors of three primary colors; dividing into a plurality of image regions having identical regions that mutually correspond between the plurality of planes; analyzing a variable indicating an identicalness of images in the image regions that correspond between the plurality of planes to determine the identicalness; and executing a sharing process between the plurality of planes based on the determined identicalness so as to generate image data representing an image constituted of the plurality of planes.

A printing system is disclosed. The printing system includes an interpreter module to generate Tagged Object Bit-plane data corresponding to drawing objects for each colorant of a device color space during rasterization a print job data and a common buffer to store the Tagged Object Bit-plane data for each colorant.

System and methods for processing and printing print jobs with a single sheet job model job model. In one embodiment, a print controller includes an interface that receives a print job, and a processing unit that initiates a processing task for a group of pages in the print job. The print controller also includes a sheet controller that establishes a single sheet job model in memory for the processing task, and that iteratively inserts sheet properties of a set of pages of the group into the single sheet job model, provides the single sheet job model with the sheet properties to the processing task, and erases the sheet properties from the single sheet job model.
