In order to make the objects, technical solutions and effects of the present invention clearer and more specific, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Example 1
The image display method provided by the invention can be executed by a terminal device, and the terminal device can be a mobile phone, a computer, a tablet personal computer, a television and the like, and the television is taken as an example for illustration.
As shown in fig. 1, the image display method provided in this embodiment includes the steps of:
s100, receiving a camera selection instruction, and determining at least one target camera according to the camera selection instruction.
Specifically, at least one target camera is determined to be selected from a plurality of cameras which are preset, and the plurality of cameras which are preset can be arranged on a television or can be independently arranged and are in communication connection with the television. In one possible implementation manner, a camera selection interface may be displayed on the television, information of a plurality of cameras is displayed, the television is provided with an input device, such as a touch screen, a remote controller, and the like, a user may select at least one camera on the camera selection interface through the input device to input the camera selection instruction to the television, and after receiving the camera selection instruction, the television takes the camera selected by the user as the target camera. In another possible implementation manner, the correspondence between the application and the camera may be stored in the television, and when the user opens the application installed on the television, the television automatically reads the camera corresponding to the application as the target camera.
And S200, receiving a display area adjusting instruction, and adjusting the image display areas of the target cameras according to the display area adjusting instruction.
After determining the target cameras, acquiring images captured by the target cameras, where each target camera corresponds to an image display area, and displaying the images captured by the target cameras in the image display areas corresponding to the target cameras, as shown in fig. 2, in one possible implementation manner, shooting parameters of each camera may be set in advance, that is, before the image display areas of each target camera are adjusted according to the display area adjustment instruction, the image display method provided in this embodiment further includes the steps of:
and receiving a first setting instruction, and setting shooting parameter parameters of each camera according to the first setting instruction.
As shown in fig. 2, a camera setting menu may be displayed on a screen of the television, and a camera position schematic diagram is displayed to distinguish each camera, through which a user may send the first setting instruction to set shooting parameters of each camera, specifically, a plurality of preset cameras may be cameras with adjustable scheduling and positions, for example, a camera lifting track may be set on a side of the television, and the cameras may be rotatable and telescopic cameras installed in the lifting track to achieve lifting, that is, the positions, angles, focal lengths and the like of the cameras may be adjusted.
In live broadcasting, in addition to the main camera of shooting the main broadcasting, the auxiliary camera of the displayed commodity is required to be shot specially in many times, in this embodiment, the target camera can be divided into a first camera and a second camera, the first camera can be the main camera of shooting the main broadcasting, the second camera is the auxiliary camera of shooting the commodity, as shown in fig. 3 and 4, for the case that the television is a rotatable television, when the screen of the television is a horizontal screen, the camera a arranged above the screen of the television can be the first camera, the camera B arranged on the side surface of the screen of the television can be the second camera, and when the screen of the television is a vertical screen, the camera B is the first camera, and the camera a is the second camera.
Specifically, as shown in fig. 6, when the television is applied to live broadcast, a live broadcast application is installed on the television, and generally, a vertical screen mode is adopted during live broadcast, so after the live broadcast application on the television is opened, the live broadcast application can send a vertical screen instruction to the television, the television is switched to a vertical screen mode, and returns a switching result to the live broadcast application, after the live broadcast application determines that screen switching is completed, a camera use request can be sent, and the television can display a camera selection interface, so that a user sends the camera selection instruction to determine the at least one target camera, or the television reads a camera corresponding to the preset live broadcast application as the target camera.
