Problems solved by technology

However, since it takes time to make such a judgment, speeding up is hindered.
Therefore, although it is considered to reduce the resolution at the time of reading so that a quick judgment can be made, the image quality of the recorded image is lowered.
Therefore, high-speed image processing and high image quality cannot be achieved at the same time, and a high-performance image processing device cannot be realized.

Abstract

Input images are efficiently judged to speed up image processing. A document with images recorded on both sides is automatically fed, and the images on the front side and the backside are individually read. Image data for each side is stored in memory. Two judgment sections judge whether the images on the front side and the backside are a specific image, respectively. If the image on either side is judged to be the specific image, copying is inhibited. The reading of the document is stopped, and subsequent copy operations are canceled.

Description

technical field [0001] The present invention relates to an image processing device that performs so-called image processing of recording an input image on a recording material. Background technique [0002] The image processing device reads an image of a document with a scanner, records and outputs the image on a recording material. In this case, it has a function of preventing illegal copying of originals of so-called confidential documents and banknotes. That is, it is judged whether or not a specific image such as a specific pattern or a background pattern is included in the image of the scanned document, and if it is recognized as a specific image, recording of the image is prohibited. Image processing for such a specific image is described in Patent Documents 1 and 2, for example. [0003] [Patent Document 1] JP-A-2002-49985 [0004] [Patent Document 2] JP-A-2005-231145 [0005] In recent years, image processing speeds have been increased in image processing devices...
