Document processing system, image forming apparatus, document processing method and computer readable medium for generating a synthetic image

摘要

A document processing system includes: a generator that generates a document image to be printed; a memory that stores document images for plural pages, the document images generated by the generator in print processing; an arithmetic unit that performs an AND operation on document images for a plural number of specific pages among the document images stored in the memory; and a display controller that causes a display device to display a synthetic image obtained by the AND operation by the arithmetic unit.

1. A document processing system comprising:
a generator that generates a document image to be printed; a memory that stores document images for a plurality of pages, the document images generated by the generator in print processing and being double-sided or continuing for multiple pages; a number of pages setting unit that sets page intervals at which document images are acquired for a set number of pages; a document image acquiring unit that acquires document images for the set number of pages set by the number of pages setting unit at the set page intervals; an arithmetic unit that performs an AND operation on document images acquired by the document image acquiring unit from the document images stored in the memory; and a display controller that causes a display device to display a synthetic image obtained by the AND operation by the arithmetic unit, wherein:
the document images generated by the generator in print processing correspond to a plurality of documents,the page intervals set by the number of pages setting unit correspond to a number of pages in each document in the plurality of documents, andthe document images acquired by the document image acquiring unit are document images acquired every nth page from the document images stored in the memory, where n=the page intervals set by the number of pages setting unit.
