IMAGE PROCESSING METHOD, COMPUTER-READABLE STORAGE MEDIUM, AND INFORMATION PROCESSING APPARATUS

摘要

An image processing method includes dividing a first image into regions according to content of the first image; generating a second image by converting a gradation of pixels of the first image into a gradation of pixels expressible in an image forming apparatus for each region; generating a piece of simulation information of a result of the image forming/outputting process based on the second image and nozzle characteristic information of the image forming apparatus; calculating an error between the first image and a third image for each of the regions, the third image being obtained by converting the piece of simulation information with the gradation of pixels of the first image; and deciding one of the second images as rendering information used to cause the image forming apparatus to perform an image forming/outputting process, based on the calculated errors between the first image and the third images.

主权项

1. An image processing method, comprising:
acquiring a first image on which an image forming/outputting process is to be performed by an image forming apparatus; storing the first image in a storage medium; dividing the stored first image into a plurality of regions according to content of the first image; generating a second image with a converted gradation by converting a gradation of pixels of the stored first image into a gradation of pixels expressible in the image forming apparatus for each of the regions; generating a piece of simulation information of a result of the image forming/outputting process to be performed by the image forming apparatus based on the second image and nozzle characteristic information for each of the regions, the nozzle characteristic information being information representing characteristics of an ink ejecting nozzle of the image forming apparatus and being generated based on dot pattern image information that is information of an image obtained as a result of an image forming/outputting process that has been performed on a certain dot pattern; storing the piece of simulation information in the storage medium; calculating an error between the first image and a third image for each of the regions, the third image being obtained by converting the piece of simulation information with the gradation of pixels of the first image; storing the error in the storage medium; and deciding one of the second images as rendering information used to cause the image forming apparatus to perform an image forming/outputting process, based on the calculated errors between the first image and the third images obtained from the pieces of simulation information that are generated respectively based on the second images that are in different gradation conversion forms for the respective regions.
