The image sensor 110 captures images printed on print media.

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

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

A pattern image is an image with a certain pattern and may be an image that displays specific information in the form of a specific pattern. Specifically, two pattern images shaped as 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 can be formed as a dot pattern printed on a printing medium. Additionally, these dot patterns may be patterned into dots of a certain size or less with low visibility.

If the pattern image is formed as a dot pattern with low visibility, the user may not be able to recognize the pattern image. However, even in this case, the image sensor 110 can 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 confirms the code corresponding to the analyzed pattern image. In another aspect, the code conversion unit 122 converts a pattern image printed on a printing medium into a code. For example, when a first pattern image is printed on a print medium, the code conversion unit 122 can analyze the first pattern image to confirm the first code, and the second pattern image is printed on the print medium. In this case, the code conversion unit 122 can confirm the second code by analyzing the second pattern image. In another aspect, the code conversion unit 122 may convert the first pattern image printed on the print medium into a first code and the second pattern image printed on the 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 this code.

Examples of command codes may include a save command code, a recording command code, a play command code, a delete command code, etc. When the electronic pen 100 recognizes a command code, it performs a specific function corresponding to each command code. You can.

The content code is a code corresponding to the print medium in which the content is stored. Since digital files corresponding to content are not actually stored in print media, the content code is actually a code corresponding to the pattern image printed on the print media. Content corresponding to the content code is stored in the electronic pen 100, and when the electronic pen 100 recognizes the content code by scanning the printing medium, it outputs the content matching the content code.

The bookmark code is a code that corresponds to the print medium on which the content will be stored. Codes used for other purposes can also become bookmark codes if they can be used to store content. For example, a content code that has already been matched to content may also serve as 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 to separate the content code and the bookmark code so that the content code is not overwritten by new content.

The code conversion unit 122 recognizes these various categories of codes and then transmits the recognized codes to the control unit 124, which performs specific functions according to the characteristics of each transmitted code. Additionally, the control unit 124 can control various functions of the electronic pen 100 while generating control signals for various components included in the electronic pen 100.

The bookmark storage unit 126 can store content on a print medium. Since the content file is not directly stored in the printing medium, technically, the bookmark storage unit 126 can store the bookmark code by matching the content with the printing medium on which the bookmark code is printed. After this 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 “printing medium with a code printed on it” is used. Here, “printing medium with a code printed on it” can be understood as a printing medium on which a pattern image corresponding to the code is printed.
