Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method for returning a video to a handheld terminal and a camera device.
Background
In the LTE broadband trunking service, video return is a typical service, and is to collect a scene picture by a handheld terminal, return the scene picture to a command center, and display the scene picture on a television wall of the command center.
There are two types of devices in the video backhaul service: a hand-held terminal and a large screen terminal.
The handheld terminal is a vertical screen device (such as a mobile phone), the aspect ratio of the screen is generally 9:16, the output pictures of the camera are wide-screen, the aspect ratio is generally 16:9, and the aspect ratio is inconsistent with the screen ratio of the handheld terminal. In order to match with the terminal screen, the installation angle of the camera is 90 degrees (at this time, when the handheld state of the terminal is vertical screen handheld, the wide screen picture collected by the camera is the picture displayed after the actual shot object rotates 90 degrees on the vertical plane), rather than 0 degree (at this time, when the handheld state of the terminal is vertical screen handheld, the wide screen picture collected by the camera is consistent with the picture displayed by the actual shot object). Fig. 1 shows a display effect of a handheld terminal and a schematic image acquired by a built-in camera therein. As shown in fig. 1, the recording preview effect seen by the user is a picture on the left side of the figure, and the picture on the right side of the figure, which is recorded and output by the camera, is a "lying down" picture (i.e. a picture that is presented after an actual subject rotates 90 degrees on a vertical plane). Therefore, in order to correctly display the recorded video during playback, camera software in the handheld terminal sets a rotation angle in the output recorded video file, and the player reads the rotation angle to perform image rendering rotation, so that the image can be correctly displayed.
The large-screen terminal comprises a dispatching desk of a command center and a television wall, the dispatching desk and the television wall are horizontal screen devices, the aspect ratio of a screen is generally 16:9 (as shown in figure 2), and the terminal screen is very large and is suitable for playing high-definition videos. The large-screen terminal is a traditional device, only decodes and plays, and does not have the functions of identifying the angle of the real-time video stream and rendering and rotating.
Due to the difference between the two types of terminals, the video return service has the following problems:
the best results are achieved only when the terminal is held across the screen (as shown in the first row in fig. 3); and when the terminal is held in the vertical screen mode, the picture of the large-screen terminal cannot be full screen (as shown in the second row in fig. 3), or the picture of the large-screen terminal is laid down (as shown in the third row in fig. 3).
Therefore, when the conventional video backhaul service exists in a vertical screen handheld terminal, the picture of the large-screen terminal cannot obtain the optimal display effect as shown in fig. 4.
