Abstract

An electronic apparatus includes a housing, a display unit installed in the housing and having a display area to display an image or a menu icon, a sensing unit installed in the housing adjacent to the display unit, having a virtual area to sense an object which is disposed over the display area of the display unit, and having a first camera to photograph and display the virtual area in a photographing mode and a second camera to extract the object from the virtual area and display a sensed image of the extracted object in a sensing mode, and a controller to analyze status of the object according to the sensed image of the object, and to determine the analyzed status of the object as a user input in the sensing mode.

Claims

1. A mobile device, comprising:

a housing having a front side and a rear side;

an input and output installed in the housing, and comprising a panel on the front side of the housing to receive a user input and to display a photographing image or a menu;

a sensing unit installed on the front side of the housing, and having a first camera and a second camera respectively having a first virtual area and a second virtual area which correspond to a display area of the panel; and

a controller installed in the housing, configured to perform a photographing mode to control the first camera to photograph the first virtual area corresponding to the display area of the panel to generate a first photographing image, and to control the display unit to display the first photographing image in the display area of the panel, and configured to perform a sensing mode to control the second camera to photograph the second virtual area including an object corresponding to the display area of the panel to generate a second photographing image including the object, to determine a state of the object of the second photographing image as the user input to the menu, and to perform a function of the mobile device according to the menu and the state of the object as the user input to the menu.

2. The mobile device of claim 1, further comprising:

a memory to store information,

wherein the controller is configured to compare the information and the state of the object and to perform the function of the mobile device according to the menu and the comparison.

3. The mobile device of claim 1, wherein the controller is configured to analyze the object of the second photographing image with respect to the display area of the panel to sense the state of the object, and to perform the function of the mobile device according to the menu and the analysis.

4. The mobile device of claim 1, wherein the controller is configured to modify the object of the second photographig image with respect to the display area of the panel to sense the state of the object, and to perform the function of the mobile device according to the menu and the modification.

5. The mobile device of claim 1, wherein the second camera photographs the object of the second virtual area when the menu is displayed in the display area of the panel.

6. The mobile device of claim 1, wherein the second camera generates the second photographing image corresponding to the second virtual area, and the controller extracts the object from the second photographing image to sense the state of the object and performs the function of the mobile device according to the menu and the extraction.

7. The mobile device of claim 1, wherein the controller is configured to display an image corresponding to the object over the menu of the display area of the panel.

8. The mobile device of claim 1, wherein the controller is configured to control the input and output unit to generate an output of the performed function of the mobile device, and the output comprises an image output through the display area of the panel, an audio output through an audio element, or a data output through an interface to an external device.

9. The mobile device of claim 1, further comprising:

an interface configured to communicate with an external device to transmit or receive data to perform the function of the mobile device,

wherein the controller is configured to perform the function of the mobile device according to the menu of the input and output unit, the state of the object as the user input to the menu, and the data of the external device.

10. The mobile device of claim 1, wherein:

the second virtual area includes a plurality of sub-objects, one of which has a higher priority than others; and

the controller selects the one sub-object with the higher priority as the object corresponding to the menu.

11. A method of a mobile device, the method comprising:

providing a housing having a front side and a rear side, an input and output installed in the housing and comprising a panel on the front side of the housing to receive a user input and to display a photographing image or a menu, and a sensing unit installed on the front side of the housing, and having a first camera and a second camera each respectively having a first virtual area and a second virtual area which correspond to a display area of the panel of the input and output unit;

using a controller processor installed in the housing, configured to perform a photographing mode to control the first camera to photograph the first virtual area corresponding to the display area od the panel to generate a first photographing image, and to control the display unit to display the first photographing image in the display area of the panel, and configured to perform a sensing mode to control the second camera to photograph the second virtual area including an object corresponding to the display area of the panel to generate a second photographing image including the object, to determine a state of the object of the second photographing image as the user input to the menu, and to perform a function of the mobile device according to the menu and the state of the object as the user input to the menu.
