Embodiment 1

[0023] Embodiment 1 of the present application provides that the present application provides a smart TV image processing method, which is applied when the connection state of the USB camera in the smart TV changes, such as figure 1 As shown, the method includes:

[0024] Step S110: When the smart TV detects the pull-out action of the target USB camera, determine whether the target USB camera is in a working state when the pull-out action occurs;

[0025] At present, most smart TVs use the Android system, and this application uses the Android system of the smart TV as an example for illustration. figure 2 It is a schematic diagram of the smart TV monitoring camera plugging and unplugging event flow, such as figure 2 As shown, because the USB device plug-in detection mechanism is pre-stored in the Android system of the smart TV, when the target USB camera connected to the smart TV is pulled out, the TV application will receive the corresponding broadcast, that is, the UsbMan...

Embodiment 2

[0043] Embodiment 2 of the present application provides a smart TV. like Figure 5 As shown, the smart TV 200 includes:

[0044] Plug-in / pull-out detection module 210 is used to determine whether the target USB camera is in working condition when the pull-out action occurs when the smart TV detects the pull-out action of the target USB camera;

[0045] Candidate camera detection module 220 is used to detect whether the smart TV is connected with a candidate USB camera when the target USB camera is in working state; wherein, the working state indicates that the smart TV displays a preview video picture; if so, then switch to the candidate USB camera to display the preview video screen; otherwise, the smart TV displays a prompt screen without a USB camera.

[0046] Those of ordinary skill in the art can understand that all or part of the steps for implementing the above method embodiments can be completed by program instructions and related hardware. The aforementioned progra...

Abstract

The application provides a smart television image processing method that is applied when a USB camera is in a connection state. The method includes the following steps: when a television application uses a target USB camera and the target USB camera is pulled out due to an unexpected state, detecting whether a smart television is also connected with other candidate USB cameras, if connected, switching to the candidate USB cameras and continuing to display a video picture, and otherwise, popping up a prompt picture indicating that no camera exists to remind a user to reinsert the camera. Afterthe USB camera that is connected with the smart television is pulled out accidentally, the process of forcibly turning off a current frame-paused picture is not required, a camera function can be restarted, and thus the user experience of using the USB camera can be improved.

Description

technical field [0001] The invention relates to the application field of smart TVs, in particular to a smart TV image processing method and a smart TV. Background technique [0002] With the development and promotion of smart TVs, there are more and more functions. In addition to the general functions of TVs, users start to use more functions carried in smart TVs, such as QQ, WeChat and other applications. Correspondingly, the application of USB cameras on Android smart TVs is becoming more and more popular. However, due to the pluggability of USB cameras, if the smart TV cannot handle the hot-swappable features of the USB cameras, it will seriously affect users. experience effect. [0003] For example, when the user uses the QQ application in the smart TV and turns on the pluggable USB camera to conduct a video chat with others, if the USB camera is pulled out due to an accident, the smart TV will display the moment when the USB camera is pulled out. The frame of the pict...
