Embodiment approach 1

[0056] One embodiment of the present invention will be described. In addition, in this embodiment, an example in which the present invention is applied to a digital color multi-function printer (MFP: Multi-Function Printer) will be described.

[0057] (1-1. Structure of digital color multifunction machine 1)

[0058] FIG. 2 is a block diagram showing a schematic configuration of a digital color multifunction peripheral (image processing device, image forming device, image reading device) 1 according to this embodiment. The digital color multifunction machine 1 has a copy function, a print function, a facsimile transmission function, a scan function, a scan to e-mail function, and the like.

[0059] As shown in FIG. 2 , the digital color multifunction machine 1 includes a color image input device 2 , a color image processing device 3 , a color image output device 4 , a communication device 5 , and an operation panel 6 .

[0060] The color image input device (image reading dev...

Embodiment approach 2

[0152] Other embodiments of the present invention will be described below. In addition, for the convenience of description, the same reference numerals are attached to components having the same functions as those in Embodiment 1, and their descriptions are omitted.

[0153] (2-1. Structure of document check processing unit)

[0154] Figure 13 It is a block diagram showing a schematic configuration of the digital color multifunction peripheral 1 of the present embodiment. As shown in the figure, the document collation processing unit 13 includes a feature point calculation unit 31 , a feature quantity calculation unit 32 , a voting processing unit 33 , a score calculation unit 35 , an accumulated score comparison unit 36 ​​, and a registration processing unit 37 . The feature point calculation unit 31 , the feature quantity calculation unit 32 , the voting processing unit 33 , and the registration processing unit 37 can use the same devices as those in the first embodiment....

Embodiment approach 3

[0209] Other embodiments of the present invention will be described below. In addition, for the convenience of description, the same reference numerals are attached to components having the same functions as those in the above-mentioned embodiment, and their descriptions are omitted.

[0210] Figure 30 It is a block diagram showing a schematic configuration of the document collation processing unit 13 included in the digital color multifunction peripheral 1 of the present embodiment. This document collation processing unit 13 is included in the digital color multifunction peripheral 1 instead of the document collation processing unit 13 in Embodiment 1 or 2.

[0211] Such as Figure 30 As shown, the document verification processing unit 13 includes a feature point calculation unit 31 , a feature quantity calculation unit 32 , a voting processing unit 33 , a similarity determination processing unit 34 , a score calculation unit 35 c , a score comparison unit 36 ​​c , and a r...

Abstract

An image processing apparatus includes: a data obtaining section for obtaining input image data; a memory in which reference image data or features of a reference image is stored; and a similarity determination process section for performing a determination process in which it is determined whether the input image data is image data corresponding to the reference image or not. The similarity determination process section changes the determination process in accordance with related information of the input image data. Consequently, it is possible to realize an image processing apparatus capable of determining a similarity between input image data and a reference image and restricting a process on the input image data in accordance with the result of the determination.

Description

technical field [0001] The present invention relates to an image processing device, an image forming device, an image processing system, and an image processing method that determine the degree of similarity between input image data and registered image data registered in advance, and perform control corresponding to the determination result. Background technique [0002] Conventionally, input image data obtained by scanning a document image by a scanner is compared with a registered image registered in advance to determine the degree of similarity between the two, and control processing of the input image data (such as copying, copying, etc.) sending, editing, etc.). [0003] As the judging method of similarity, known for example, by OCR (Optical Character Reader) etc. extract keyword (key word) from image, thereby carry out the method of matching by keyword; A ticket image, a method of matching features passing through a ruled line (refer to Patent Document 1 (Japanese La...
