Embodiment Construction

[0025] First, refer to figure 1 An example of an image processing apparatus according to an example embodiment is described. The image processing device may be a device included in or connected to a printer (not shown), and may generate raster image data to be supplied to the printer.

[0026] exist figure 1 In the example shown in , the raster image processor (RIP) section 10 processes the print data written in the page description language (PDL) that has been input to the image processing apparatus from an external device (for example, a personal computer or a removable storage medium) Interpretation is performed, and the print data is converted into intermediate image data. Examples of intermediate image data include, but are not limited to, display list data. Examples of formats of intermediate data include ones in which each object (e.g., font, graphic map, continuous-tone image) that is one of the image elements that make up an image is represented for each scanline i...

Abstract

The present invention relates to an image processing device, comprising a plurality of auxiliary processing apparatuses and distribution portions, wherein the plurality of auxiliary processing apparatuses performs predetermined processing on image data, the distribution portion divides one page of image data into a plurality of processing units, the plurality of processing units are distributed to the plurality of auxiliary processing apparatuses, the distribution portion calculates that how many blocks into which one page of image data are divided during a time range when one auxiliary processing apparatus processes one page of image data according to the number of the auxiliary processing apparatuses and the number of processing units which can be simultaneously received and processed by one auxiliary processing apparatus, one page of image data are divided into a plurality of processing units, the number of the processing units is equal to the calculated dividing number, and the plurality of processing units are distributed to the plurality of auxiliary processing apparatuses respectively.

Description

technical field [0001] The present invention relates to image processing devices. Background technique [0002] A digital printer or digital multifunction device (a multifunction device with printer, scanner, and copying functions) performs various image processing operations to perform tasks such as printing, including interpretation of print data written in a page description language, interpretation-based Raster image generation from the final print data, color matching processing such as color space conversion, and compression and expansion of the raster image data to be temporarily stored or transmitted. In high-speed systems used in fields such as professional printing, some of the above image processing operations may be performed by auxiliary processing devices such as hardware accelerators to increase the processing speed of the system. To further increase processing speed, a printer system can have multiple hardware accelerators, and multiple hardware accelerators...
