Abstract

PURPOSE:To discriminate a picture of filled out paper from a picture to be described without changing color and density by storing picture information on the filled out paper to a storage device in advance and producing the filled out paper based on the stored picture information. CONSTITUTION:The picture information on the filled out paper such as document format or the like is stored in a picture storage section 21 in advance after dividing it into character frame position information and image information. A picture producing section 22 produces an output document data by the character frame position information and the image information from the storage section 21 and transmits it to a facsimile FX25 via a communication control section 23. The FX25 produces the format of the filled out paper, and the operator fills up the input picture required for the filled out paper and returns it via the FX25 and the control section 23. A picture discriminating section 24 receives the picture on the paper after filling out from the FX25, compares it with the information from the storage section 21 so as to discriminate the picture before filling out and after it, eliminates the character frame, and applies characters to a character recognizing device 26 after cutting out the characters at each character.

Description

[Detailed Description of the Invention] (1) Description of the field to which the invention pertains The present invention uses a simple image input/output device d for 9 image input/output method 2% to punch out a blank entry form and fill it out. Enter the entry form and enter the characters 9 written on the entry form.
The present invention relates to an image input/output method that allows input images such as figures to be extracted separately from the entry form itself.

(2) Explanation of the conventional technology Conventionally, in single-print forms such as character recognition forms and mark sheet cards that are used to input 5-character and graphic data, the 6-print column for specifying the 1-size format is By printing in a color different from the characters and figures to be filled in later, such as dropout blue (dropout color), the characters and figures to be filled in later can be printed in a different color, such as dropout blue (dropout color). A method is used that allows images to be identified.

It is common to write black characters and figures in the character frame using dropout blue, and when using a manual device such as a facsimile, the blue part is not manually written. Only the characters and figures of jMQ are input as necessary information.

Figure 1 is an example of an entry form, and area 1 surrounded by dotted lines in the figure
1 is the entry area, 12 is the sensor mark.

16 is a character frame. Conventionally, images of figures and characters included in the second illustration area 11 are printed in blue, and input images are written using a black writing instrument. When such a form is input using a black and white two-color reading sensor such as a widely used facsimile machine, only the desired input li1+1 image is extracted, with the dropout blue removed due to the characteristics of the sensor. Can fc.

However, with this method of identifying using different colors,
It is necessary to describe the area 11 using a color, such as dropout blue, that is different from the color of the marking tool to be filled in. Many commonly used devices are unable to meet the requirements for color-coding and recording in this way, and the forms themselves are generated using popular image input/output devices such as facsimiles. It was difficult to separate and identify only the input image after entry.

(3) Purpose of the Invention The present invention, in order to eliminate these drawbacks, stores the image information of the entry form in a storage device in advance and generates the entry form based on the accumulated image information. The purpose of this method is to make it possible to distinguish between the image on the entry form and the image to be filled in without changing the color or eI&, and will be described in detail below with reference to the drawings.

(4) Description of structure and operation of the invention FIG. 2 shows an embodiment of the invention, in which 21 is an image storage section, 22 is an image generation section, and 26 is a communication control section.

24 is an image recognition unit, 25 is a 7AKUNMI+), and 26 is a character recognition device.

In the image storage section 21, 9 ii! II image information is stored. J image information is stored divided into, for example, character frame position information and image information such as sentence r, and the information format of each information includes a binary image representing the image itself, a line segment of a line figure, etc. Many types of information formats are possible, such as graphic information and mosaic graphics. The image generation section 22 obtains the character frame position information and image information from the image storage section 21.

A character frame and characters are generated, and output form data (an image of an entry form) to be notified to the facsimile 25 is generated. The communication control unit 26 performs communication control for inputting and outputting images to and from the facsimile 25 . Therefore, the image generation section 22 transmits the image of the entry form to the facsimile 25 via the communication control section 23, causes the facsimile 25 to generate the entry form, and teaches the operator the format of the entry form. The operator outputs the facsimile 25&'i+ entry form and inputs the completed form, and the operator fills in a safe input image on the entry form he has been taught and sends it via the facsimile 25K.

The image identification unit 24 receives an image of the completed form from the facsimile 25 and generates, for example, a character frame of the entry form based on the image information (for example, character frame position information) of the entry form obtained from the one-image storage unit 21.

An operation is performed to compare the generated one and the one received from the communication control unit 26, and based on the comparison result, the image before filling out (for example, a character frame) in the image of the sheet after filling out and the image of the written result. identify. That is, character recognition device I+
After removing two character frames from 726, character extraction is performed for each character to provide nine individual character images. The character Kt+tk device 26 then performs character recognition for each character.

(5) Explanation of Effects As explained above, the present invention enables the identification of the pre-input image and the inscribed image even if they are of the same color, making it possible to use inexpensive black-and-white facsimiles that are highly popular. There is an advantage. Therefore, for example, the center side has a form format, and according to the request, the form is output to a facsimile installed at a remote location, one character or other necessary information is written, inputted from the facsimile transmitter, installed at the center side, and
It is possible to process forms using a character recognition device, and an inexpensive black and white fax machine can be used.
