The application program center can provide and store various application programs. The application may be a game, an application, or some other application associated with a computer system or other device that may be run on a display device. The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.
A schematic diagram of a user interface in a display device 200 according to an exemplary embodiment is illustrated in fig. 4. As shown in fig. 4, the user interface includes a view display area 201, wherein, for example, the view display area 201 includes a layout of one or more different items. And a selector in the user interface indicating that the item is selected, the position of the selector being movable by user input to change the selection of a different item.
In some embodiments, the view display area 201 is a scalable view display. "scalable," may mean that the view display area 201 is scalable in size or proportion on the screen, or that the items in the view display 201 are scalable in size or proportion on the screen.
"item" refers to a visual object displayed in a view display area of a user interface in the display device 200 to represent corresponding content, such as icons, thumbnails, video clips, and the like. For example: the items may represent movies, image content or video clips of a television show, audio content of music, applications, or other user access content history information.
Further, the item may represent an interface or a collection of interfaces on which the display device 200 is connected to an external device, or may represent a name of an external device connected to the display device, or the like. Such as: a signal source input Interface set, or a High Definition Multimedia Interface (HDMI), a USB Interface, a PC terminal Interface, and the like.
It should be noted that: the view display area may present Video chat project content or application layer project content (e.g., web page Video, Video On Demand (VOD) presentations, application screens, etc.).
A "selector" is used to indicate where any item has been selected, such as a cursor or a focus object. Positioning the selection information input according to an icon or menu position touched by the user in the display 200 may cause movement of a focus object displayed in the display device 200 to select a control item, one or more of which may be selected or controlled.
The focus object refers to an object that moves between items according to user input. Illustratively, the focus object position is implemented or identified by drawing a thick line through the item edge.

As shown in fig. 6, a frame of picture in an image data stream acquired when a user sends a "take picture" instruction is displayed on the first user interface 201-1, and at this time, the user may scan a shared picture, or may click "save" or take a picture again; when the user clicks "save", in response to the "save" instruction, the user interface changes to display the picture just saved in the second user interface 201-2 of the view display area 201 as shown in fig. 7. At this time, the user obtains a display scale of the television display area of 16:9 picture.
In some exemplary embodiments, the preview screen is formed by continuously displaying, at a preset frame rate, the first user interface after the controller captures an image acquired by the camera according to a second aspect ratio, where the second aspect ratio is a display aspect ratio. Illustratively, the display aspect ratio is 16:9, respectively.

Illustratively, the first user interface is a preview interface and the second user interface is a photo presentation interface.
In some exemplary embodiments, the preview screen is a screen cut at a preset scale.
Illustratively, the preset ratio is a pixel ratio of 16: 9; after a preview interface of the mirror application is started at the television end according to the instruction of a user, the camera takes the pixel ratio of the width to the height of an image as 4:3 (the camera captures a video stream consisting of a plurality of frames of image data), in order to adapt the aspect ratio of the television to 16:9, the system Hardware Abstraction Layer (HAL) is used for processing an original image shot by a camera according to the pixel ratio of 16: and 9, intercepting the image, performing compression coding on the intercepted image, and transmitting the image to an upper application (for example, a social television mirror application), wherein the upper application analyzes the image, and continuously displays the image on a preview interface at a certain frame rate (the frame rate value is not limited herein), so as to form a camera preview picture.

The Camera object is used for controlling a Camera switch, configuring Camera parameters, managing Camera start/stop preview, photographing and the like. Camera has many interfaces for managing cameras, configuring parameters, starting/stopping previews, etc. the takePicture interface is used to start the photograph.
For example, when a preview interface displays a preview screen of a shooting scene of a television camera, a user can select an image storage ratio to be in a full-screen mode, and can also increase or change a special effect of the preview screen; when a user clicks 'take a picture', a frame of image is acquired when a taking instruction of the user is received, the user interface is switched to a photo display interface from a preview interface, and the image is displayed on the photo display interface.
In some exemplary embodiments, the first aspect ratio is an aspect ratio of 4: 3.
