Abstract

Described embodiments provide a method and user equipment for selectively transferring image data from user equipment to a coupled external device. The method may include determining whether user equipment is coupled to an external device, receiving selection inputs from a user for selecting at least one of applications installed in the user equipment when the user equipment is determined as being coupled to the external device, and selectively transferring image data produced in the user equipment based on the selected application. The method may further include controlling the coupled external device to display the transferred image data on a display unit of the coupled external device.

First claim

What is claimed is:

1. A method for selectively transferring image data from user equipment to a coupled external device, the method comprising:
determining whether user equipment is coupled to an external device based on a detection signal that is generated by the user equipment when the user equipment is coupled to the external device through at least one of direct connection, indirect connection, and wireless connection;
determining whether the coupled external device is a preregistered device or a non-registered device when the user equipment is determined as being coupled to the external device;
retrieving, from a memory of the user equipment, information on at least one application and an image data transfer option selected with respect to the coupled external device when the coupled external device is determined as the preregistered device;
receiving selection inputs from a user for i) selecting at least one of applications installed in and simultaneously running in the user equipment and ii) selecting an image data transfer option to be applied to the selected at least one of the applications, when the user equipment is determined as the non-registered device; and
selectively transferring image data produced in the user equipment to the external device by performing, according to the selected image data transfer option identified by the retrieved information or the received user selection inputs, one of i) transmitting image data produced by the selected at least one application, identified by the retrieved information or the received user selection inputs, to the external device and ii) restricting the image data produced by the selected at least one application from being transmitted to the external device while transmitting unselected image data produced by unselected applications,
wherein the user equipment has a dedicated display unit for displaying data processed by the user equipment, and the external device has a display unit which is different from the dedicated display unit of the user equipment; and
wherein the selected image data transfer option identified by the received information or the received user selection inputs includes information indicating allowance or restriction on transmission of the image data produced by the selected at least one application to the external device.

2. The method of claim 1 , further comprising:
controlling the coupled external device to display the selectively transferred image data on the display unit of the coupled external device.

3. The method of claim 1 , wherein the receiving selection inputs from a user includes:
providing a user interface to the user for selecting at least one of the applications and for selecting one of a positive image data transfer option, a negative image data transfer option, and a mirrored image data transfer option, as an image data transfer option associated with the coupled non-registered external device; and
receiving the selection inputs for selecting at least one of the applications and for setting the image data transfer option.

4. The method of claim 3 , including:
determining whether the user wants to register the coupled non-registered external device as a preregistered device with information on the selected applications and the selected image data transfer options after the receiving the selection inputs; and
storing the coupled external device as the preregistered device and the information on the selected applications and the selected image data transfer option in the memory of the user equipment when the user wants to register the coupled non-registered external device as a preregistered device.

5. The method of claim 3 , wherein the selectively transferring image data includes:
transferring image data produced by the selected at least one of the applications to the coupled external device when the positive image data transfer option is selected as the image data transfer option associated with the coupled external device.

6. The method of claim 3 , wherein the selectively transferring image data includes:
restricting image data produced by the selected at least one of the applications from transfer to the coupled external device when the negative image data transfer option is selected as the image data transfer option associated with the coupled external device.

7. The method of claim 3 , wherein the selectively transferring image data includes:
transferring image data produced by all of the applications installed in the user equipment to the coupled external device when the mirrored image data transfer option is selected as the image data transfer option associated with the coupled external device.

8. The method of claim 1 , comprising:
establishing a host-device connection when the user equipment is determined as being coupled to an external device.

9. The method of claim 8 , wherein the establishing includes:
obtaining display device information of the coupled external device;
determining whether to reconfigure an initial display setting of the user equipment based on the obtained display device information;
reconfiguring the initial display setting based on the obtained display device information and storing as a host-device connection display setting associated with the coupled external device when the reconfiguration is necessary;
otherwise, storing the initial display setting as the host-device connection display setting associated with the coupled external device.

10. The method of claim 9 , including:
controlling the coupled external device to display the selectively transferred image data on a display unit of the coupled external device based on the host-device connection display setting.

11. The method of claim 9 , wherein the display device information includes a device identity (ID), a screen size, a display direction, and a dot per inch (DPI).

12. A user equipment for selectively transferring image data to a coupled external device, the user equipment comprising:
an interface unit configured to be connected to a corresponding interface unit of an external device, to generate a detection signal when the user equipment is coupled to an external device through at least one of direct connection, indirect connection, and wireless connection, to transmit and receive data to/from an external device, and to transfer image data produced by applications installed in the user equipment to a coupled external device;
a touch screen panel configured to receive selection inputs from a user i) for selecting at least one of applications and ii) for selecting one of a positive image data transfer option, a negative image data transfer option, and a mirrored image data transfer option as an image data transfer option;
a display unit configured to display image data produced by applications installed in the user equipment and to display a user interface for enabling the user to select at least one of applications and to select one of a positive image data transfer option, a negative image data transfer option, and a mirrored image data transfer option as an image data transfer option associated with the coupled external device;
a controller configured to determine that the user equipment is coupled to an external device upon the reception of the generated detection signal of the interface unit, to set an image data transfer option of the coupled external device based on the received selection input with the selected at least one applications, and to selectively transfer image data produced in the user equipment based on the set image data transfer option with the selected application to the coupled external device by performing one of i) transmitting image
