Abstract

PURPOSE:To read out information printed with a drop-out color by inputting the information of a non-drop-out color input means to a recognizing device when non-drop-out color information exists, and at the time of its absence, inputting the information of a drop-out input means. CONSTITUTION:An information presence detecting circuit 8 checks the presence of non-drop-out color information on a prescribed position of a document 1. Since information printed by the drop-out color is corrected on the position when the non-drop-out information exists, an image stored in a memory 6 is inputted to a recognizing part 9 and recognized. When the circuit 8 decides the absence of the non-drop-out color information on the prescribed position, an image stored in a memory 7 is inputted to the recognizing part 9 and recognized. Consequently, characters printed by the drop-out color can be recognized and office work can be made efficient.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an optical character reading device (hereinafter referred to as an OCR device) K.

[Conventional technology]

Conventional OCR devices generally write information to be printed on a form in a non-dropout color, and print frames that are not to be read or instructions regarding entry, etc. in a dropout color.

[The problem that the invention is trying to solve]

The conventional OCR apparatus described above always optically ignores dark and guar colors. Therefore, if it becomes mud,
It is not possible to automatically perform control such that information for one color is ignored in other cases, and characters in non-dropout colors are recognized.

However, there are the following requirements. The information that is written on the @ slip is usually the same information as usual, but from time to time it is necessary to change it to other information. For example, the position on the form is
In most cases, Tokyo (or its code) is written, but
Sometimes it is necessary to write down another prefecture (or its code). In such cases, print Tokyo in dropout color on the form, and if it is other than Tokyo, write the name of the prefecture. It is written in a non-dropout color on top of Tokyo, and if the character is written in a non-dropout color, it is recognized, and if the character is not written in a non-dropout color, it is a doro, Recognizing characters printed in Gua9to color can improve the efficiency of office work. However, such character recognition was not possible with the above-mentioned conventional OCR device.

[Means for solving problems]

The OC device of the present invention includes a non-dropout color input means for inputting information on a non-dropout color, a dropout color input means for inputting information on both a dropout color and a non-dropout color, and a dropout color input means for inputting information on a non-dropout color. The method includes a detection means for inputting information from a color input means and detecting the presence or absence of non-dropout color information at a predetermined position on a form, and a recognition means, and the detection means includes information on a non-dropout color. When the g is detected, the information of the non-dropout color input means is input to the g.
When the detection means detects that there is no non-dropout color information, the information from the doro and guatato input means is input to the recognition means and recognized. .

〔Example〕

Next, please refer to the drawings for the present invention! 52 will be revealed.

FIG. 1 is a block diagram of an embodiment of the present invention. In the form IK, normal information is printed in dropout color, and information that modifies this normal information is printed in bowl dropout color. FIG. 2 shows an example in which information of characters 10 is printed in a dropout color at a predetermined position on a form l. FIG. 3 is a diagram showing an example in which characters 11 are written in 1 non-dropout color on the information printed in the dropout color shown in FIG. 2 to correct the °C information.

In Figure 1, 1 is a form read by OCR, and light source 2
The light emitted from the screen is reflected on the form l, passes through the filter 3, and is input to the scanner 4. At this time, the dropout color is compressed by the filter 3 and does not reach the scanner 4. In other words, only non-dropout color information is input to the scanner 4. This information is stored in memory 6. Further, the light reflected from the form 1 is input to the scanner 5 without passing through a filter. In this case, information on both the dropout color and the non-dropout color is stored in the memory 7.

Reference numeral 8 denotes an information presence/absence detection circuit which checks whether or not there is information on a non-dragged color at a predetermined position on the form 1. If there is non-drop or guact information, the information printed in dropout color at that position has been corrected, so you need to recognize the corrected information. That is, in this case, the image stored in the memory 6 is input to the recognition unit 9 and recognized.

If the information detection circuit 8 determines that there is no information on a non-dropout color at a predetermined position, it is necessary to recognize the information on a dropout color at that position. That is, in this case, the image stored in the memory 7 is input to the recognition section 9 and recognized. On this occasion,
This image is only a dropout color image.

[Effects of the Invention] According to the present invention, it is also possible to read information printed in dropout color on a form, and when horizontally changing information printed in dropout color, it is possible to read information printed in dropout color. It is also possible to read the changed information by writing over it in a non-dropout color.

This method 1. Information that hardly changes is printed on the form in dropout color, and only when there is a need for change, it is written on top of it in a dropout color. It is possible to improve the efficiency of office work.
