Accordingly, the user can easily store the information described in the actual calendar and the like in the memory of the mobile terminal.

7A and 7B are image diagrams for describing a method of displaying information in a mobile terminal according to a third embodiment of the present invention.

Referring to FIG. 7A, when a signal for acquiring an image is input, the controller 180 displays an image including the external object 720 obtained through the camera 121 on the display unit 151. In a third embodiment, the external object is a watch. The controller 180 recognizes the external object 720 included in the image by using an object recognition program. That is, the controller 180 recognizes that the external object 720 is a clock and the current time is 11 o'clock. The controller 180 extracts only schedule information after 11 o'clock from among schedule information stored in the memory 160. Referring to FIG. 7B, the controller 180 displays the extracted information 731 and 732 on the display unit 151. In addition, the controller 180 projects the extracted information 731 and 732 onto the peripheral wall surface 710 of the clock 700.

Accordingly, the user can display his schedule information on the display unit of the mobile terminal and project the surroundings of the clock by tilting the clock using a camera. Therefore, the user can easily grasp his schedule information.

8A and 8B are image diagrams for describing a method of displaying information in a mobile terminal according to a fourth embodiment of the present invention.

Referring to FIG. 8A, when a signal for obtaining an image is input, the controller 180 displays an image including an external object 810 obtained through the camera 121 on the display unit 151. In a third embodiment, the external object is a phone book. The controller 180 recognizes the external object 810 included in the image by using an object recognition program. That is, the controller 180 recognizes that the external object 810 is a phone book. Referring to FIG. 8B, the controller 180 extracts a phone book list stored in the memory 160 which is a function of the mobile terminal associated with the recognized phone book, and displays a phone book list screen on the display unit based on the extracted phone book list. do. The phone book list screen includes a recognized image 820, a phone book list 830, a correction icon 830, and an additional icon 840. When the user selects the correction icon 840 using the user input unit 130, the controller 180 executes a function of modifying the phone book list 830. For example, the controller 180 may place the cursor on a specific name. If a user selects a specific name and phone number from the recognized image 820 using the user input unit 130 and then selects the additional icon 850, the controller 180 displays the selected name and phone number. The phone book list 830 is further stored.

Accordingly, the user can easily store the information described in the phone book in the memory.

9A and 9B are image diagrams for describing a method of displaying information in a mobile terminal according to a fifth embodiment of the present invention.

Referring to FIG. 9A, when a signal for acquiring an image is input, the controller 180 acquires an image including the external object 910 through the camera 121. In a third embodiment, the external object is a picture frame. The controller 180 recognizes the external object 910 included in the image by using an object recognition program. That is, the controller 180 recognizes that the external object 910 is a picture frame. Referring to FIG. 9B, the controller 180 displays a memo window 920 for taking a memo on the display unit. A user inputs contents into the memo window 920 using the user input unit 130. The controller 180 stores the input content in the memory 160 in correspondence with the recognized external object. Thereafter, when the user illuminates the recognized external object 910 again using the camera 121, the controller 180 extracts the input content from the memory 160 and displays it on the display unit 151. do. For example, when the external object is a picture frame and the input content is a 'birthday present', when the user illuminates the picture frame by using the camera 121, the controller 180 reads from the memory 160. The sentence “birthday present” is extracted and displayed on the display unit 151.

Accordingly, the user can easily grasp the content related to the specific external object.

The information display method in the mobile terminal and the mobile terminal using the same are not limited to the configuration and method of the above-described embodiments, but the embodiments may be all or all of the embodiments so that various modifications may be made. Some may be optionally combined.

In addition, it should be noted that the above embodiment is for the purpose of description and not of limitation. In addition, those skilled in the art will understand that various embodiments are possible within the scope of the technical idea of the present invention.
