Abstract

PURPOSE:To eliminate the keyboard correction work of an operator and to facilitate the registration and retrieval of image information by registering plural candidates which a character recognition device recognized as keywords. CONSTITUTION:If recognition results are plural candidates when the character recognition device 35 recognizes characters and the character string of the recognized results are registered in a recording medium 33 as code information, the operator registers all data outputted as the candidates as the keywords in an image information registration/retrieval device 32 without judging whether the candidates are accurately recognized or erroneously recognized. When image information and the recognized results outputted from the device 35 are registered in the device 32, the recognition of the recognized results outputted from the device 35 and key input by the operator are omitted.

Description

[Detailed Description of the Invention] [Summary] An image in which image information read by a scanner or the like is stored in a storage medium such as an optical disk or memory along with a keyword for searching, and the image information is searched when necessary and displayed/printed. Regarding the information registration and search device, when registering keywords by character recognition, the operator does not need to check the recognition results, and for the purpose of efficient image information registration. Along with the recognition means, there is an image information registration means for converting the character recognition result obtained by the character recognition means into code information and registering the code information as a keyword in the storage medium together with the image information, and an image information registration means for converting the character recognition result obtained by the character recognition means into code information and registering this as a keyword in the storage medium together with the image information. In an image information registration and retrieval device comprising an image information search means for searching image information based on a keyword, the image information registration means recognizes the plurality of characters when there are a plurality of character recognition results obtained by the single character recognition means. The configuration is such that all results are registered in the storage medium as keywords of image information.

[Industrial application field]

The present invention relates to an image information registration and retrieval device that stores image information read by a scanner or the like together with keywords for retrieval in a storage medium such as an optical disk or memory, retrieves the image information when necessary, and displays or prints the image information.

An image information registration and retrieval device is a device that performs character recognition when registering image information and registers it as a keyword of the image information.In recent years, the amount of information to be registered has increased and the amount of input work has increased. Therefore, there is a need for an image information registration and retrieval device that allows easy input.

[Conventional technology]

In conventional image information registration and retrieval devices, keywords are input when registering image information by an operator manually inputting code information using an input/output device, or by using a character recognition function to input code information that becomes a keyword from image information. The conventional method is to take out the recognition result, check the recognition result, and if the recognition result is incorrect, the operator manually corrects the recognition result.

FIG. 3 shows an example of the configuration when registering and searching image information. In the figure, an image information registration and search device 32 searches and registers image information. The input/output device 31 issues registration/search instructions to the operator or the image information registration/search device 32. The storage medium 33 (including internal memory, etc.) stores image information and search keywords. The scanner device 34 inputs image information to be registered. The character recognition device 35 recognizes the given image information and notifies the image information registration and search device 32 of character code information as a result of the recognition.

FIG. 4 shows an example of recognition of image information. (A) of the same figure shows character information that has been converted into an image and is to be recognized by the character recognition device 35. (B) in the same figure is a character string extracted as a candidate as a result of recognition with respect to (A) in the same figure.

When the character string shown in FIG. 4A is recognized, the character recognition device 35 may extract an incorrect first candidate as shown in FIG. 2B. In this case, the operator would check the recognition results and, if the recognition results were incorrect, correct the keyword by displaying the next candidate. In this case, the image to be recognized is ``Daytime'', but the first candidate is ``Yamanaka'', and since the recognition result is incorrect, the operator displays the second candidate as the next candidate. The second candidate is currently under offer, and the recognition result is also incorrect, so the next candidate is displayed. This time, the third candidate is “Nichiichi°” and the correct recognition result was obtained.The operator then instructs to register this third candidate “Tanaka” as a keyword.This allows the operator to create image information using the content of the third candidate. can be taken out.

[Problem to be solved by the invention]

However, in the conventional technology, each time image information is registered in a storage medium, an operator is required to manually enter a keyword using keys, which makes the operation complicated.

In addition, the operator takes out the keyword and checks whether the recognition result displayed on the input/output device is correct. If a recognition result of incorrect recognition is output, check until the correct recognition result is displayed. There were issues that needed to be worked on.

Furthermore, when searching for image information, only the first candidate keyword is registered for the image information, so there is a problem that it is difficult to obtain the desired image information even if keywords from the recognition results from the second candidate are used. Ta.

The present invention has been made in view of the above points, and an object of the present invention is to provide an image information registration and retrieval device that eliminates the need for an operator to check the recognition results when registering keywords by character recognition, and that performs efficient image information registration. purpose.

Since the keyword is registered as a keyword, the operator does not have to correct the keyword. Furthermore, by registering a plurality of keywords, image information can be registered and searched without correction by an operator.

[Means to solve the problem]

FIG. 1 shows a diagram explaining the principle of the present invention. In the figure, image information 10 is information for performing character recognition, character recognition means 11 performs character recognition of the image information at the time of image information registration, and character recognition results 12 are obtained by the character recognition means 11. It is information. The image information registration means 14 stores the character recognition result 1 obtained by the character recognition means 11.
When two or more character recognition results 12 exist, all of the plurality of character recognition results 12 are registered in the storage medium 16 as keywords of the image information 10.

[Effect]

DESCRIPTION OF THE PREFERRED EMBODIMENTS [Embodiment] An embodiment of the present invention will be described below with reference to the drawings. Incidentally, since the configuration of the apparatus of the present invention is similar to that shown in FIG. 3, a description thereof will be omitted.

FIG. 2 shows a flowchart for registering image information according to an embodiment of the present invention. The operator prepares the original to be input and gives instructions from the keyboard of the input/output device (
Step 20), the image information of the document is read by the scanner device 34 (Step 21). The image information input from the scanner device is stored in the image information registration and search device 3.
2 (step 22).

The image information taken into the image information registration and search device 32 is displayed on the input/output device 31 (step 23).

Next, the operator looks at the image information displayed on the input/output device 31 and, if the range to be registered in the storage medium 33 is not specified (step 24), specifies the registration range (step 25).

The image information registration and retrieval device 32 extracts image information in the registration range designated by the operator from the image information and supplies it to the character recognition device 35 (step 26).

The character recognition device 35 performs character recognition processing on the image information supplied from the image information registration and search device 32 by recognizing character patterns and converting them into code information (step 27).

The image information registration and search device 32 stores the keyword that is the recognition result and the input image information in the storage medium 33 (step 28), thereby completing the registration operation.

This is because character recognition is performed by the character recognition device 35, and when the recognition result character string is registered in the storage medium 33 as code information, if the recognition result is multiple candidates, the operator or the operator determines whether the candidate is correctly recognized. All items output as candidates without determining whether they are misrecognized are registered as keywords in the image information registration/retrieval device 32.

When registering the image information and the recognition results output from the character recognition device 35 in the image information registration and retrieval device 32 as described above, the recognition results output from the character recognition device 35 as shown in FIG. Operator confirmation and key human effort are omitted.

This operation will be explained with reference to FIG. (A) in the figure is image information of the recognition target read by a scanner etc., and this information is input to the character recognition device 35, and (B) in the figure
When the recognition results shown in are extracted, the recognition results for all four candidates: the first candidate "Yamanaka", the second candidate "Shinchu", the third candidate "Naka", and the fourth candidate "Kochu" is registered as a keyword in the image information registration and search device 32.

In addition, the input/output device can be registered without operator intervention! Instead of selecting candidates for correct recognition while looking at 31, the character recognition device 35 automatically selects candidates for correct recognition.

In the case of searching for image information, keywords are input from the information registered in the image information registration and search device 32 through the input/output device 35 to obtain desired image information.

Therefore, by registering multiple recognition results for one image information when registering recognition results, even if the first candidate is misrecognized, the second and subsequent recognition results can also be registered as keywords. Therefore, desired image information can be searched and displayed.

〔Effect of the invention〕

As described above, according to the present invention, there is no need for confirmation or correction by an operator, so it is easy to register user image information in a storage medium, and therefore input efficiency can be improved even if the number of input items is large. Therefore, it is practically useful.
