Abstract

PURPOSE:To perform input of information of an electronic computer effectively by automatically cutting out an area by a cutting out circuit, when an operator sets a cursor at the first area to read using a pointer. CONSTITUTION:When a form 1 comes in front of a scanner 2, the scanner scans the entire surface of the form and temporarily stores a signal in a picture memory 3. Then the signal is read out from the memory 3 in succession and displayed on a display 4. On this display screen, a cursor 8 is overlapped and displayed. An operator brings the cursor 8 to the front of the area to read by using a pointer 5. Receiving a cursor location signal from the pointer 5, a cutting out circuit 7 cuts out an area 183-01 and sends a signal only within the area from the memory 3. When a form 1-b comes in front of the scanner, the cursor is made transferred to the head of ''183-01''.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information input device that can easily specify information to be read from characters written on an object, etc., automatically read the information, and use the information as input to a computer, etc. .

Conventionally, there is an OCR as a device that automatically reads characters and the like. OCR can read various characters such as numbers, kana, alphabets, symbols, and kanji, but it cannot determine which part of the characters written on the form should be read, so it cannot be specified in advance by the program. (This is called a formatting program.) It reads only the characters in the specified area (1).Since ordinary machines and devices cannot understand the meaning of this, it is necessary to read the contents written on the form. This is because it is impossible to automatically determine all areas that need to be determined and read.

In addition, in postal code reading machines, which is an important field of use for OCR, a red frame is provided in the case of manual reading, and the area to be read is defined within this frame. However, it was created using an address printing machine, line printer, etc.! 1', Regarding the address of the messenger,
There is no red frame (・), so the position of the postal box number must be automatically identified.Since the rule of thumb is that the postal code must be written at the beginning of the address block, it is usually written in the text section. The beginning of the postal code can be set as the position where the postal code is written.1
However, in many cases, the surface of the mail is printed with the sender's name and address other than the addressee, advertisement printing, other characters, figures, etc., and it is difficult to automatically identify the postal code area from among these. Extremely long f1. Therefore, even if you perform statistical processing to determine the correct answer rate, you cannot obtain a correct answer rate of 100 cm. It is said that the strength is necessary.

The purpose of the present invention is to carry out the process of determining the specified route from the big picture that humans want to obtain, in order to complete such an evacuation. Houki゛・λ゛!.

The poetry of the characters themselves, which can be pressed quickly, is read by OCR by inputting the line 5 information input device r4r.

The present invention will be described in detail with reference to Examples below. ! 1 day in the morning.

FIG. 1 shows an example of a form in which information to be inputted is written. FIG. 2 shows an OI/τ diagram of one example of the present invention.

In the figure, form l is in front of scanner 2
(The means of transporting the image to the front of the scanner is our OCFt technology.) The scanner scans the entire surface of the document and temporarily stores the signal in the image memory 3.11 The image memory 3 and the resolution spray 4 sequentially read the signals. l through ν・-. The display status of Form 1-(a) is shown in Figure 3. The character area that the operator should visually read from the display in Figure 3 is 1.
83-01 This can be easily done by humans if rules are given. A cursor 8 is displayed superimposed on the display screen. The operator uses pointer 5 to bring this cursor 8 to the beginning of the area to be read. Techniques for moving a cursor on the screen are also known, and the pointer 5 may be a joystick, maras, keys, or the like.

The cutter 7 receives the cursor position signal from the pointer 5, cuts the area 183-01 107, and stores it in the image memory 3.
Only signals within the area are sent to the character reading circuit 7. In this case, since the tJ method of the area to be read is constant, it is easy to cut out even the beginning of the area by specifying it with a cursor. Further, even if the dimensions of the region are variable, the cutout circuit can be easily constructed using ordinary techniques as long as the position of the region is specified.

Next, when the form 1-G) comes in front of the scanner, move the cursor to the beginning of "183-01".

In form 1-(83, 303-60 at the upper left corner was not the reading area, but in 1-03), 183-01 at the upper left corner was the reading area. Such judgments can be made very easily by humans, but it is extremely difficult to make them mechanically.

As described above, according to the present invention, it is possible to realize a device that correctly specifies the area to be read and inputs information from a form containing complicated figures, etc.
