Image processing device, image processing system, non-transitory computer readable medium, and image processing method

An image processing system comprising:

• an image reading device that reads a printed document;
• an image object separating unit that separates the printed document read by the image reading device into image objects;
• a page aggregation state determining unit that determines a page aggregation state of the read printed document based on a layout of the image objects separated by the image object separating unit by (1) receiving a detection of a boundary line from an identified overlap between objects located within identified sections of the read printed document and (2) by comparing the boundary line with a layout of a page aggregation state stored in advance, thereby identifying which page aggregation state of the read printed document;
• a printing direction determining unit that determines a printing direction of each of image objects determined by the page aggregation state determining unit based on the features of each of the image text objects separated by the image object separating unit;
• and
• a document format converting unit that converts a document format of the read printed document based on the results of the determination by the page aggregation state determining unit and the printing direction determining unit.

An image processing device comprising:

• an image object separating unit that separates an original page of a read printed document into objects and determines the type of each object, wherein the type of at least one of the objects is text and the type of another one of the objects is graphic;
• a printing direction determining unit that determines a printing direction of each object determined based on the type of each object separated by the image object separating unit and based on a erected direction detected for each text object;
• and
• wherein when multiple objects are included in the original page, different rotating processes are applied to each respective objects included in the original page so that the erecting process is applied to only a text object included in the original page and so that the rotating process is not applied to graphic objects, and the rotating process is set individually for the respective graphic objects.
