a communication unit; and a controller configured to cause: transmitting resolution information including a plurality of resolutions that are supported by the wireless device to a second wireless device; receiving an entire image including a first image and a second image from the second wireless device if a resolution of the first image is not one of the plurality of resolutions; displaying the first image by removing the second image from the received entire image when the entire image is received; and receiving the first image from the second wireless device without the second image if the resolution of the first image is included in the resolution information, the second image being an image that is added to the first image such that a resolution of the received entire image corresponds to one of the plurality of resolutions. ## Claims ### Claim 1 A first wireless device supporting Wi-Fi Direct service, the first wireless device comprising: a display; a communication unit configured to communicate with a second wireless device; and a controller configured to: transmit resolution information to the second wireless device by using Real-Time Streaming Protocol (RTSP), the resolution information including a plurality of resolutions that are supported by the first wireless device; receive a transmitted image comprising a first image and a second image from the second wireless device if a resolution of the first image is not one of the plurality of resolutions, wherein the first image is a first portion of an original image wherein the first portion corresponds to a displayed region of the original image displayed at the second wireless device in a first position orientation, and wherein the second image is an image that is added to the first image such that a resolution of the received transmitted image corresponds to one of the plurality of resolutions; control the display to display the first image on a partial area of the display by removing the second image from the transmitted image; receive a third image from the second wireless device when the second wireless device is changed to a second position orientation and a resolution of the third image is one of the plurality of resolutions, wherein the third image is a second portion of the original image and the second portion corresponds to a displayed region of the original image displayed at the second wireless device in the second position orientation; and control the display to display the third image on an entire region of the display. ### Claim 2 (depends on 1) The first wireless device of claim 1, wherein the controller is further configured to control the display to display the first image in a first area of a split screen and display media content in a second area of the split screen, wherein the media content was being displayed when the transmitted image was received. ### Claim 3 (depends on 2) The first wireless terminal of claim 2, wherein the controller is further configured to control the display to change a size of the displayed first image when an input is received to a boundary between the first area and the second area of the split screen. ### Claim 4 (depends on 2) The first wireless terminal of claim 2, wherein the controller is further configured to control the display to display the first image in a changed resolution to match the first area. ### Claim 5 (depends on 2) The first wireless terminal of claim 2, wherein the controller is further configured to control the display to display: the first image in the first area without changing the resolution; and a size adjustment control to change a size of the first image within the displayed first area. ### Claim 6 (depends on 1) The first wireless terminal of claim 1, wherein the second portion of the original image corresponds to a cropped portion of the original image. ### Claim 7 (depends on 1) The first wireless terminal of claim 1, wherein the second portion of the original image corresponds to an entire portion of the original image. ### Claim 8 (depends on 1) The first wireless terminal of claim 1, wherein the third image comprises a portion of the original image that is not included in the first image. ### Claim 9 (depends on 1) The first wireless terminal of claim 1, wherein the controller is further configured to control the display to: display a mirror function off option; cease displaying the third image in response to a selection of the displayed mirror function off option; and control the display to display an indicator for restoring display of the third image. ### Claim 10 (depends on 1) The first wireless terminal of claim 1, wherein the resolution of the transmitted image is selected by the second wireless device from the plurality of resolutions. ### Claim 11 (depends on 1) The first wireless device of claim 1, wherein the second image is a black image. ### Claim 12 (depends on 1) The first wireless device of claim 1, wherein the controller is further configured to control the display to display: media content on an entire region of the display prior to receiving the transmitted image from the second wireless device; and the first image on a partial region of the display by removing the second image after receiving the transmitted image. ### Claim 13 (depends on 12) The first wireless device of claim 12, wherein the first image is displayed overlapping the displayed media content. ### Claim 14 (depends on 13) The first wireless device of claim 13, wherein the controller is further configured to control the display to display an image adjustment window for controlling at least one of a size or transparency of the first image such that the image adjustment window is displayed on a first area of the display while the first image is displayed on a second area of the display. ### Claim 15 (depends on 14) The first wireless device of claim 14, wherein the controller is further configured to cause the first image to increase its transparency in response to an input applied via the image adjustment window such that the displayed media content is visible through the first image. ### Claim 16 (depends on 12) The first wireless device of claim 12, wherein the controller is further configured to: control the display to display a control window comprising at least one button for controlling an operation of the second wireless device on a first area of the display while the first image is displayed on a second area of the display; and control an operation of the second wireless device in response to an input applied via the at least one button. ### Claim 17 (depends on 1) The first wireless device of claim 1, wherein the controller is further configured to control the display to display at least one image adjustment window for adjusting a size or a position of the first image, the at least one image adjustment window overlapping the first image. ### Claim 18 A method for controlling a first wireless device supporting Wi-Fi Direct service, the method comprising: transmitting resolution information to a second wireless device by using Real-Time Streaming Protocol (RTSP), the resolution information including a plurality of resolutions that are supported by the first wireless device; receiving a transmitted image comprising a first image and a second image from the second wireless device if a resolution of the first image is not one of the plurality of resolutions, wherein the first image is a first portion of an original image wherein the first portion corresponds to a displayed region of the original image displayed at the second wireless device in a first position orientation, and wherein the second image is an image that is added to the first image such that a resolution of the received transmitted image corresponds to one of the plurality of resolutions; displaying, on a display, the first image on a partial area of the display by removing the second image from the transmitted image; receiving a third image from the second wireless device when the second wireless device is changed to a second position orientation and a resolution of the third image is one of the plurality of resolutions, wherein the third image is a second portion of the original image and the second portion corresponds to a displayed region of the original image displayed at the second wireless device in the second position orientation;
