도 2 는 본 발명에서 문서를 한번에 인식하는 방법에 대한 플로우 챠트2 is a flowchart of a method for recognizing a document at one time in the present invention.

본 발명은 웹 카메라, 핸드폰(IMT-2000) 카메라, PDA 카메라를 이용하여 명함이나 기타 인쇄된 문자를 인식하고 인식된 정보를 저장 관리하는 것으로, 카메라를 이용하여 문서정보를 한번에 인식시키거나 여러 구역으로 나누어 인식시킨 후 통합하여 하나의 문서로 활용하도록 하는 것이다.The present invention recognizes a business card or other printed text using a web camera, a mobile phone (IMT-2000) camera, a PDA camera and stores and manages the recognized information. Divided into two parts, it is recognized and then integrated into one document.

본 발명은 카메라가 내장되거나 연결되는 통신기기에 있어서, 카메라로 문서를 촬영하고 내장된 문자인식 프로그램에 의해 촬영된 문서를 인식한 후 인식된 결과를 저장시키는 것으로, 먼저 입력시키고자 하는 정보를 선택하는 입력 정보 선택과정과, 선택된 정보를 카메라로 촬영하는 촬영과정과, 촬영된 화면을 보고 취득을 원하는 정보 영역을 선택하는 영상정보 선택과정과, 선택된 영상정보를 문자인식 프로그램을 작동시켜 문자로 인식시키는 문자인식 과정과, 인식된 문자를 저장하는 저장과정을 반복하여 수행하므로서 원하는 전체 영역에 대한 문자를 인식하여 저장시킬 수 있도록 한다.According to the present invention, a communication device having a built-in camera or a connected device is used for photographing a document with a camera, recognizing a document taken by a built-in text recognition program, and storing the recognized result. The input information selection process, the photographing process of photographing the selected information with the camera, the image information selection process of selecting the information area to be acquired by viewing the captured screen, and the selected image information to be recognized as a character by operating a text recognition program. By repeatedly performing the character recognition process and the storage process of storing the recognized character to be able to recognize and store the character for the entire desired area.

카메라를 이용한 문서정보 입력은 전체 문서를 여러 개의 구역으로 나누어 각 구역별로 인식과정을 거치도록 하여 전체 문서정보를 입력시키거나, 한번에 전체문서를 촬영하여 인식시킬 수 있는 것으로, 카메라로 촬영된 문서의 인식이 가능하여야 하는 전제조건에 따라 해상도가 우수한 카메라를 사용하는 경우 구역으로 나누지 않고 한번에 인식시킬 수도 있는 것이다.Document information input using a camera can input the entire document information by dividing the entire document into several sections and recognizing each section, or recognizing the entire document at once. Depending on the prerequisite to be able to recognize, when using a camera with high resolution, it can be recognized at once without dividing into zones.

위와 같이 인식되는 구역을 선택하는 방법은 카메라로 촬영된 프리뷰(preview) 화면을 보고 원하는 영역을 선택하도록 하고, 인식능력에 따라 여러 개의 구역으로 나누어 전체문서를 인식시키거나 한번에 전체문서를 인식시키도록 한다.The method to select the area recognized as above is to select the desired area by looking at the preview screen shot by the camera, and divide the area into several areas according to the recognition ability to recognize the whole document or the whole document at once. do.

인식된 문서 중 명함정보는 회사, 이름, 주소, 전화번호 등과 같은 일련의 정보를 데이터 베이스에 저장하여 명함정보를 활용할 수 있도록 하고, 신문이나 잡지 등의 일반 문서정보는 텍스트 관리프로그램에 의해 관리되도록 하여 인식된 정보를 활용할 수 있도록 한다.Among the recognized documents, business card information stores a series of information such as company, name, address, phone number, etc. in the database so that business card information can be utilized, and general document information such as newspapers and magazines can be managed by text management program. To use the recognized information.

이러한 본 발명은 먼저 입력을 원하는 정보를 선택하는 입력 정보 선택과정을 실시하여 명함을 인식시킬 것인가 책, 신문, 잡지 등의 문서를 입력시킬 것인가를 선택한다.The present invention first performs an input information selection process for selecting information desired to be input to select whether to recognize a business card or input a document such as a book, a newspaper, a magazine, or the like.

여기서 명함은 인식된 정보를 이용하여 추후에 그 사람을 찾아야 하는 정보로 활용하여야 하고, 그 이외의 문서정보는 단순히 텍스트로 저장되어진 후 문서내용을 확인하는 정도로 활용된다.Here, the business card should be used as information to find the person later using the recognized information, and other document information is simply stored as text and used to confirm the document contents.

문서 선택과정에서 원하는 문서가 선택되면 카메라를 작동시켜 선택된 문서를 카메라로 촬영하도록 하고, 촬영된 문서는 액정화면에 프리뷰(preview)형태로 표시되며, 사용자는 프리뷰의 촬영화면을 보고 인식을 원하는 영역을 선택하도록 한다.When the desired document is selected in the document selection process, the camera is operated to capture the selected document with the camera, and the captured document is displayed in the form of a preview on the LCD screen. To select it.

여기서 프리뷰 형태로 보여지는 화면에는 인식이 가능한 영역이 표시되게 되며 사용자는 인식가능한 영역의 중심을 원하는 영역의 중심으로 이동시키면 영역의 선택이 완료되게 된다.Here, the recognizable area is displayed on the screen displayed in the preview form, and the user selects the area by moving the center of the recognizable area to the center of the desired area.

여기서 선택영역은 카메라의 해상도나 문자인식 처리 능력에 따라 달라지게 되는 것으로, 전체 영역을 한번에 인식하도록 할 수도 있고, 처리 능력의 한계 때문에 전체를 여러 영역으로 나누어 인식하게 할 수 있는 것으로, 한번에 인식하는것이 편리하나 처리능력에 한계가 있기 때문에 여러 구역으로 나누어 인식시키게 된다.In this case, the selection area depends on the resolution of the camera or the character recognition processing capability. The entire area may be recognized at once, or because of the limitation of the processing capability, the selection area may be divided into several regions. It is convenient, but due to the limited processing capacity, it is recognized as divided into several zones.

이같이 촬영된 문서의 인식영역을 선택하면 선택된 영역의 영상정보를 획득하고, 획득된 영상정보를 문자인식 프로그램을 작동시켜 문자로 인식시키고, 인식된 문자정보는 데이터 베이스에 저장시킨다.When the recognition region of the photographed document is selected as described above, image information of the selected region is acquired, the acquired image information is operated as a character by operating a character recognition program, and the recognized character information is stored in a database.

여기서 명함의 경우는 회사, 이름, 주소, 전화번호를 분리하여 저장되도록 데이터 베이스를 구성하고, 각 데이터 베이스에 분산하여 저장하도록 하되 추후에 명함정보를 확인하거나 활용할 경우는 분산된 명함정보를 한번에 활용할 수 있도록 한다.In the case of business cards, the database should be configured to store company, name, address, and phone number separately, and then distributed to each database and stored in each database. To help.

즉 명함 정보는 각각의 정보를 분류하여 저장하도록 하므로서 추후에 원하는 명함을 원하는 정보로 쉽게 찾아 활용할 수 있도록 하는 것이다.In other words, the business card information is to classify and store each information so that later you can easily find the desired business card as the desired information.

명함 정보 이외의 문서정보는 문자로 인식된 데이터를 저장하여 일반 텍스트 관리 프로그램에 의하여 관리되도록 하여, 문서정보 데이터로 활용할 수 있도록 한다.Document information other than business card information stores data recognized as characters to be managed by a general text management program, so that the document information can be utilized as document information data.

인식결과가 데이터 베이스에 저장되면 촬영을 종료하겠는가를 선택하여야 하며, 이는 문서를 한번에 읽어낼 경우는 해당되지 않고 여러 구역으로 나누어 읽어낼 경우만 해당되는 것으로, 한번에 전체 문서정보를 확인할 수 없기 때문에 한 구역의 문서정보를 읽어내면 다음 구역의 문서정보를 읽어내는 식으로 연속하여 문서정보를 읽도록 한다.When the recognition result is saved in the database, it is necessary to select whether to end the shooting. This is not the case when reading the document at once, but only when reading the document in several sections. When reading the document information of the section, read the document information continuously by reading the document information of the next section.

따라서 전체 문서에 대하여 전부 인식을 하지 않는 한 프로그램을 종료시키지 않고 전체 문서 내용의 입력이 완료되면 문서정보의 인식과 보관 관리동작이 완료되는 것이다.Therefore, when the entire document contents are inputted without terminating the program unless all the documents are fully recognized, the recognition and storage management operation of the document information is completed.

본 발명은 때와 장소에 관계없이 문서정보를 인식하여 저장하고 이를 활용할 수 있도록 하는 것으로, 자판을 이용하지 않고 카메라를 이용하여 문서정보를 인식하도록 하여 문서인식이 간편하게 이루어질 수 있도록 하는 것이다.The present invention is to recognize and store document information regardless of time and place, and to utilize it, and to recognize document information by using a camera without using a keyboard to facilitate document recognition.

그리고 본 발명은 문서입력 장소의 제한을 받지 않고 문서입력을 자판으로 하지 않아 입력의 편리함과 신속함을 줄 수 있는 것이다.In addition, the present invention is not limited to the document input location and can be given a convenient and quick input without the keyboard input.
