1 is a configuration diagram of an electronic pen according to an embodiment, and FIG. 2 is an exemplary diagram of a detailed configuration of a digital processor and a memory of FIG. 1 .

Referring to FIG. 1 , the electronic pen 100 may include an image sensor 110, a digital processor 120, a memory 130, a speaker 140, and the like.

Referring to FIG. 2, the digital processor 120 may include a code conversion unit 122, a control unit 124, and a bookmark storage unit 126, and the memory 130 includes a voice data DB 132 and a bookmark DB. (134) may be included.

The image sensor 110 captures an image printed on a print medium.

Print media refers to various types of media on which images are printed. For example, the print media may be paper media such as books, cards, newspapers, magazines, flyers, pamphlets, and posts. As another example, the printing medium may be school supplies such as a desk, a pencil case, a pencil, and an eraser. In addition, all media capable of printing images may be print media to which one embodiment may be applied.

The image sensor 110 may capture a pattern image printed on a print medium.

The pattern image may be an image having a certain pattern and displaying specific information in the form of a specific pattern. Specifically, two pattern images formed in different patterns may correspond to different information. For example, a first pattern image shaped as a first pattern may correspond to first information, and a second pattern image shaped as a second pattern may correspond to second information.

The pattern image may be formed as a dot pattern printed on a print medium. In addition, such a dot pattern may be patterned into dots of a certain size or less having low visibility.

When a pattern image is formed of such a low-visibility dot pattern, a user may not be able to recognize the pattern image. However, even in this case, the image sensor 110 may capture a pattern image and recognize a pattern included in the pattern image - for example, a dot pattern.

The code conversion unit 122 analyzes the pattern image captured by the image sensor 110 and checks a code corresponding to the analyzed pattern image. In another aspect, the code conversion unit 122 converts a pattern image printed on a print medium into a code. For example, when a first pattern image is printed on a print medium, the code conversion unit 122 may analyze the first pattern image to check the first code, and the second pattern image is printed on the print medium. In this case, the code conversion unit 122 may check the second code by analyzing the second pattern image. In another aspect, the code conversion unit 122 may convert a first pattern image printed on a print medium into a first code and convert a second pattern image printed on a print medium into a second code.

The code confirmed by the code conversion unit 122 is transmitted to the control unit 124, and the control unit 124 can perform a specific function according to these codes.

Various classifications can be applied to codes. Of course, this classification can be arbitrarily changed and variations are possible in applying the contents of the present invention.

Codes can be classified into character codes, special key codes, command codes, content codes, bookmark codes, and the like.

The character code is a code for character input. Specifically, there may be a character code corresponding to the keyboard. For example, there may be a character code corresponding to the alphabet 'c' on the keyboard, and there may be a character code corresponding to the Korean consonant 'a'.

The electronic pen 100 according to an embodiment may form words using character codes.

The special key code is a code corresponding to a key representing a special function on the keyboard. As an example of the special key code, there may be an enter key code corresponding to the enter key, and there may be an ESC keyboard corresponding to the ESC key. Also, there may be a backspace key code corresponding to the backspace key.

The electronic pen 100 according to an embodiment can edit words or perform other functions using these special key codes.

The command code is a code that allows the electronic pen 100 to perform a specific function. Examples of command codes include a storage command code, a recording command code, a playback command code, and a delete command code. When the command code is recognized, the electronic pen 100 performs a specific function corresponding to each command code. can

The content code is a code corresponding to a print medium on which content is stored. Since the digital file corresponding to the content is not actually stored in the print medium, the content code is actually a code corresponding to the pattern image printed on the print medium. In the electronic pen 100, content corresponding to the content code is matched and stored. When the electronic pen 100 recognizes the content code through scanning of the print media, the content matched with the content code is output.

The bookmark code is a code corresponding to a print medium in which content is to be stored. Codes used for other purposes can also become such bookmark codes if they can be used for content storage. For example, a content code already matched with content may also become a bookmark code for storing new content, depending on the embodiment. Of course, depending on the embodiment, the electronic pen 100 may include a function of separating the content code and the bookmark code so that the content code is not overwritten with new content.

The code conversion unit 122 recognizes these various types of codes and then transmits the recognized codes to the control unit 124, and the control unit 124 performs a specific function according to the characteristics of each transmitted code. In addition, the controller 124 may control various functions of the electronic pen 100 while generating control signals for various elements included in the electronic pen 100 .

The bookmark storage unit 126 may store content in a print medium. Since the content file is not directly stored in the print medium, the bookmark storage unit 126 can technically match and store the corresponding bookmark code and content with respect to the print medium on which the bookmark code is printed. After such matching, the electronic pen 100 can scan the corresponding bookmark code and output content matched to the bookmark code. For convenience of explanation, the expression "printed media on which codes are printed" is used. Here, "printed media on which codes are printed" can be understood as printed media on which a pattern image corresponding to the code is printed.
