Problems solved by technology

[0004] However, in the structure disclosed in JP-A-4-314263, the image after the binarization process and the edge extraction process is used as the feature data of each input image, and the comparison of the pattern matching method is performed. , implicitly restricts that the originals that have been read separately multiple times will not be rotated, so there is a problem that the matching point cannot be detected correctly when the actual two images are pattern matched

Embodiment approach 1

[0067] FIG. 1 is a block diagram illustrating an internal configuration of an image processing system including an image processing device according to the present embodiment. The image processing system according to Embodiment 1 includes an operation panel 1 , an image input device 3 , an image processing device 5A, and an image output device 7 .

[0068] The operation panel 1 is composed of a liquid crystal display device, various switches, etc., displays information to be reported to the user, and accepts various selection operations by the user.

[0069] The image input device 3 is a reading unit for optically reading an image of a document, and includes a light source for irradiating a document for reading, an image sensor such as a CCD (Charge Coupled Device), and the like. In the image input device 3 , a reflected light image from a document set at a predetermined reading position is formed on the image sensor, and RGB (R: Red, G: Green, B: Blue) analog electrical signa...

Embodiment approach 2

[0132] In Embodiment 1, image composition is performed using the text collation processing unit 53 , but a configuration may be adopted in which a function of text collation processing is added to the image composition processing. In this embodiment, the configuration of an image processing device in which text collation processing is added to image composition processing will be described.

[0133] FIG. 21 is a block diagram illustrating the internal configuration of an image processing system including the image processing device of the present embodiment. The image processing system according to Embodiment 2 includes an operation panel 1 , an image input device 3 , an image processing device 5B, and an image output device 7 . Among them, the configuration other than the image processing device 5B is completely the same as that of the first embodiment.

[0134] The image processing device 5B is composed of an AD conversion unit 51, a speckle correction unit 52, an image syn...

Embodiment approach 3

[0147] In Embodiments 1 and 2, each process is realized by hardware, but it may also be configured to be realized by software processing.

[0148] FIG. 27 is a block diagram illustrating the internal configuration of an image processing apparatus in which the computer program according to this embodiment is installed. 100 in the figure represents an image processing device according to this embodiment, specifically, a personal computer, a workstation, or the like. Image processing device 100 includes CPU 101 , and hardware such as ROM 103 , RAM 104 , hard disk 105 , external storage unit 106 , input unit 107 , display unit 108 , and communication interface 109 are connected to CPU 101 via bus 102 . CPU101 controls each part of said hardware according to the control program prestored in ROM103.

[0149] The RAM 104 is a volatile memory that temporarily stores various data generated during the execution of the control program or the program code (executable program, intermediat...

Abstract

The invention provides a image processing device and method, a image reading and forming device and a recording medium. A document matching process section contains: features calculating section for extracting a plurality of connected components from input document images and calculating the centroids of the connected components and consequently determining the feature points; a features calculating section for calculating features of the document image from the distance between the calculated feature points; and a vote processing section for voting for a similar image in accordance with the calculated features, and uses the functions of this document matching process section and extracts the feature point from each of the two images and then correlates between the extracted feature points and consequently joins the images.

Description

technical field [0001] The present invention relates to an image processing method for synthesizing two images, an image processing device, an image reading device, an image forming device and a recording medium. Background technique [0002] Conventionally, in an image forming apparatus such as a copying machine, one image is generated by partially overlapping multiple input images, and an image is formed on the generated image. Therefore, as an image processing apparatus for a copier suitable for copying an image of an original document on a recording medium, when copying an image of an original document larger than the scanner size which is the maximum size readable by the image reading unit, For each partial image of the plurality of partial images that are partially and repeatedly divided from the image of the original document, after performing a plurality of reading processes, the plurality of read partial images are joined to restore the original image of the origina...
