Patent Images
1. A method of displaying a screen of a portable device having at least one display unit, the method comprising:
- detecting generation of a screen-changing event;
determining a plurality of layers according to a type of data to be displayed on the screen and whether the portable device is connected to an external image output device, wherein the plurality of layers are determined by classifying the data to be displayed;
allocating a corresponding layer property indicating an internal output image frame or an external output image frame, to each of the plurality of layers;
generating the internal output image frame and the external output image frame by combining at least a part of the plurality of layers according to the corresponding layer property of each of the plurality of layers; and
displaying the internal output image frame on the display unit, and transmitting the external output image frame to the external image output device.

10. A portable device, comprising:
-
at least one display unit; a controller which detects generation of a screen-changing event, determines a plurality of layers by classifying data displayed on a screen of the display unit according to a type of the data to be displayed on the screen and whether the portable device is connected to an external image output device, and allocates a corresponding layer property indicating an internal output image frame or an external output image frame, to each of the plurality of layers; and an image-processing unit which combines at least a part of the plurality of layers according to the corresponding layer property of the plurality of layers to generate the internal output image frame and the external output image frame, displays the internal output image frame on the display unit, and transmits the external output image frame to the external image output device. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
