A storage and transmission method.

The mobile communication terminal has a built-in camera and provides a multimedia message service that stores an image taken by an object and stores it in an album or attached to a message. Albums store photos or videos and users open and manage albums when needed.

The multimedia message service transmits a multimedia message created by attaching an image to a text message or attaching a multimedia file.

When a user transmits an image in which a document is taken using a multimedia message service, the amount of data to be transmitted is large compared to the amount of information, which is inefficient and the resolution is not high.

Accordingly, the present invention has been made in view of the above problems, and the document through the character recognition of the mobile communication terminal to transmit the document obtained by extracting the character information by the character recognition from the document image taken by the camera to the message transmission service Its purpose is to provide a storage and transmission method.

According to an aspect of the present invention, there is provided a method of performing character recognition on a document image photographed by a camera, and outputting a processed result as a document; Storing and managing the output document in a document storage box; If the document attachment mode is selected in the message composition mode, the method comprises creating a message by attaching a document stored in the document storage box.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

A mobile communication terminal according to an embodiment of the present invention includes a camera for photographing an object; An image processor which processes an image obtained by a camera; A terminal modem accessing a mobile communication network and providing a communication service; It consists of a keypad that receives user commands.

The camera photographs the object, and the image processing unit corrects the image obtained by the camera to improve image quality, change the format, or compress the data to minimize the data size, and the terminal modem accesses the mobile communication network to provide a communication service, and a keypad. Receives the user's command and passes it to the terminal modem.

The work structure of the mobile communication terminal includes: a photographing job of photographing an object; An image processing operation for processing an image obtained by the camera; A character recognition operation of recognizing a character in the image processed image; It consists of a message sending operation for sending a message to the document obtained by the character recognition.

The shooting operation focuses on the object that the user wants to take and outputs an optimal image. The image processing operation improves image quality by changing, compressing, and pixel correcting an image format.

The character recognition operation tracks the character position in the imaged image and recognizes a character matching the character image. The message transmission task transmits a document obtained by text recognition to a message transmission service of short message, multimedia message, e-mail and fax.

A method of managing a document extracted from a document image in the base environment of the mobile communication terminal will be described.

1 is a flowchart illustrating a method of storing and transmitting a document through text recognition of a mobile communication terminal according to an exemplary embodiment of the present invention. As shown in FIG. 1, a result of processing text recognition on a document image photographed by a camera is shown. Outputting to a document; Editing a document by correcting an error character in the document by a user; Storing and managing the edited document in a document storage box; In the message composition mode, when the user selects to attach a document, the method includes creating a message by attaching a document stored in the document storage box.

The mobile communication terminal selects a document image or a stored document image taken by the user and determines whether to perform character recognition.

When character recognition is executed by the user, the mobile communication terminal changes the selected document image into a format suitable for character recognition. In order to increase the character recognition rate, pixel correction is performed to increase the resolution of the character image.

The character position is tracked and the matching character image is searched or features of the character pattern are extracted and compared with the reference character pattern to determine the matching character.

When the character recognition is completed, the images and characters used for the character recognition are displayed one-to-one so that the user can correct and edit the character in error. When the user finishes editing and confirms saving the document, the document name input window is displayed, the document name is input, and the document is saved.

When the user selects attach document from the message composition menu, the mobile terminal outputs a list of stored documents and attaches the document selected by the user to the message. In this case, the message may be attached as an attachment or may be attached to the message.

When the user finishes composing the message, the mobile communication terminal transmits the message to the destination terminal.

An example in which a user takes a document and executes text recognition to transmit a document obtained to the other party will be described.

Suppose a user selects a document image and selects text recognition.

When the user takes a document with the camera and selects text recognition, the text recognition status bar is displayed on the display window. Alternatively, selecting character recognition outputs a list of stored document images. When the user selects a document image, a text recognition status bar is displayed.

The document image list is stored in the document image database when the object is taken with the camera and the document image is selected as the image type, or stored in the document image database when the image property is changed.

When character recognition is selected by the user, the mobile communication terminal performs character recognition on the photographed document image. Character recognition tracks the position of characters in the document image and outputs the document by one-to-one conversion to characters matching the character image.

When the character recognition status bar is filled up and the character recognition is completed, the character recognition result is displayed on the display window. At this time, the recognized text and the text image are output in a one-to-one correspondence, so that the user may conveniently check the text recognition result.

The user finds an error in the character recognition result, moves the cursor to the error character and presses edit to edit the error character. That is, the user edits an error character in the document that is the result of the character recognition and corrects the correct document. After the modification, the user confirms the document storage and saves the document.

Documents are stored in the document library, and the contents of the documents are modified or deleted according to the user's choice.

When the user selects the message transmission service and attaches the stored document, the mobile communication terminal transmits the message with the document attached to the destination terminal. In detail, when a document attachment is selected by the user, a list of documents stored in the document storage box is output on the display window. The user selects the document to attach from the list of stored documents and attaches it.

If the user selects Insert from the Edit menu while composing a message, the list of documents stored in the document library is displayed on the display window. The user selects a document from the document list and attaches it to the message content.

The user completes the message and confirms the transmission to send the message with the document attached to the destination terminal.

As described in detail above, the present invention has an effect of increasing the information management efficiency of a mobile communication terminal with severe storage space by reducing the storage capacity required for document storage by storing and managing a document created by extracting text information from a document image. have.

In addition, the amount of data required for transmission of the document content attached to the message is small, it is effective to increase the message transmission efficiency.
