Embodiment 1

[0095] Please refer to figure 1 and figure 2 , this embodiment provides a terminal screen lock method combined with a camera. When the terminal is stored, it can still ensure that the head-mounted device plays or displays the content of the terminal screen normally, and can also realize secret control.

[0096] The methods include:

[0097] First, after starting the mask layer (display) on the top layer of all applications on the terminal, turn on the flashlight of the terminal, and set the camera of the terminal to take pictures periodically.

[0098] After the mask layer is activated, all touch events of the terminal will be intercepted through the mask layer.

[0099] The setting of the mask layer can realize the "false lock screen" effect that the terminal can still play the original app content, and the headset connected to it can still play the terminal display content normally, but cannot touch the terminal. Wherein, the interception method may be to intercept all t...

Embodiment corresponding Embodiment 1

[0127] This embodiment corresponds to Embodiment 1, and provides a specific application scenario:

[0128] The user connects to the mobile phone through a headset (a device similar to Google Glass, but there is no built-in operating system in the glasses, and all displayed content is projected from the mobile phone to the headset through hdmi), and uses the headset to watch what is being played on the phone. Video for a better viewing experience. However, the mobile phone needs to keep the screen bright during the process to ensure that both the mobile phone and the headset can play normally. If the mobile phone lock screen is put in the pocket, the screen will be black, and the content on the headset will not be displayed; if the mobile phone is not locked and the screen is put in the pocket, it is easy to cause accidental touches. Using the method provided in Embodiment 1, by displaying a transparent mask layer on the screen of the mobile phone, the mobile phone can continu...

Embodiment 3

[0135] This embodiment corresponds to Embodiment 1 or Embodiment 2, and provides a computer-readable storage medium on which a computer program is stored. When the program is executed by a processor, it can realize the above-mentioned embodiment 1 or Embodiment 2. The steps included in a terminal lock screen method combined with a camera. The specific steps will not be repeated here, please refer to the description of Embodiment 1 or Embodiment 2 for details.

[0136] In summary, the present invention provides a terminal lock screen method combined with a camera and a storage medium, which can not only maintain the normal playback of the head-mounted device, but also effectively prevent accidental touches; further, it can be realized directly by using the terminal flashlight and the camera. Unlocking in the bag has the advantages of simple operation, wide applicability and low cost; further, it can also support convenient and accurate manipulation of the terminal in the dark, ...

Abstract

The invention provides a terminal screen locking method combined with a camera and a storage medium, and the method comprises the steps: turning on a flash lamp of a terminal, and setting the camera of the terminal to take pictures periodically; setting a mask layer on the uppermost layer of all applications of the terminal; intercepting all touch events of the terminal through the mask layer; when the characteristic that the finger completely shields the camera is recognized according to the shot image, shrinking the mask layer to a specified size; and when the finger features are not recognized, restoring the mask layer to the original state. According to the invention, normal playing of the head-mounted equipment can be maintained, and mistaken touch can be effectively prevented; furthermore, unlocking in the bag can be realized by directly utilizing a terminal flash lamp and a camera, and the method has the advantages of simplicity and convenience in operation, wide applicability and low cost; furthermore, the terminal can be conveniently and accurately controlled in the dark to interact with the app; furthermore, the electric quantity of the terminal can be saved.

Description

technical field [0001] The invention relates to the field of head-mounted devices, in particular to a method for locking the screen of a terminal combined with a camera and a storage medium. Background technique [0002] More and more head-mounted devices support outputting screens of terminals (mobile phones, tablets, etc.) to the head-mounted devices for display. Based on the current technology, if the terminal is locked, it will not be able to continue outputting images to the headset. However, if the terminal does not lock the screen, accidental touches are prone to occur, especially when it is placed in a pocket; and when the terminal (such as a mobile phone) is placed in the pocket and the screen is locked, it is difficult to operate the terminal, and thus cannot control the head-mounted device. display. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a terminal lock screen method combined with a camera a...
