ordinate representing width of sampling frame and center of sampling frame
The ratio of (a) to (b),
which represents a preset length of the optical fiber,
representing a preset width.
The working principle and the beneficial effects of the technical scheme are as follows:
when the screen is projected, if no other person exists, the person who calls can be directly determined on the screen of the screen projection equipment, so that the screen projection equipment is convenient and quick, and the problem of privacy disclosure is not worried. For example: when only one person is the user himself, the strategy of synchronous display can be adopted. When only two people exist, namely the user and the family members, the incoming call page can be displayed by adopting a pause screen projection picture and protecting privacy; when the number of people is more than two, the incoming call page is displayed by continuously projecting the screen and protecting the privacy. In addition, when the number of people is determined through the image, the size of the sampling frame is adjusted according to the difference between the shot far part and the shot near part in the image, and the accuracy of human body detection when the sampling frame moves in the image is improved. In addition, the judgment conditions of the incoming call page display strategy can be comprehensively considered by the place where the screen projection equipment is located and the personnel in the place.
In one embodiment, the phone receives an incoming call (including WeChat, qq, whatsapp voice, etc.) while currently in the screen-shot state.
When the incoming page is about to be started, a global variable for stopping refreshing the picture is set to the bottom layer in the ActivityManagerService through the WindowManagerService.
And when the incoming call interface is displayed, setting a flag which is not displayed on the virtual screen for the layer of the incoming call app.
When the incoming call is ended and activity finish is performed, setting a global variable for stopping refreshing the picture set before cancellation to the bottom layer in the Activity manager service through the Windows manager service.
In the surfaceFlinger, whether the virtual screen is refreshed or not is controlled according to the set global variable.
Wherein, if the caller ID needs to be turned, the surfaceFlinger stops refreshing the virtual screen before turning the screen.
The incoming call privacy protection method of the embodiment solves the problem that the virtual screen and the mobile phone can only be played synchronously during screen projection. When the mobile phone calls, the virtual screen keeps displaying the picture before the call, and the mobile phone end can normally answer the call. The incoming call is made when the screen projection operation is performed on the mobile terminal (such as a mobile phone and a tablet), and the incoming call page is not displayed on the screen projection equipment, so that the privacy of a user is protected.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
