Terminal Device Screen Mirroring for Clear Display Photography
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current terminal devices have limited shooting functions, particularly when attempting to photograph display content from a distance or with obstructions, leading to incomplete or distorted images.
Innovation Solution
A method and device that enable a terminal device to establish a short-range wireless communication connection with another terminal device, allowing the display content to be mirrored and displayed in real-time on the first terminal device's preview screen, facilitating clear photography.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the user photographs display content from a distance or with obstructions, then the shooting function can be used in various scenarios, but the image quality becomes incomplete or distorted
Solution Approach 1:
The patent uses screen mirroring technology to create a copy of the display content on the photographing device's own screen. Instead of capturing the physical display through the camera, the system transmits the display content data wirelessly and renders it as a preview image on the photographing device, eliminating the need for optical capture and avoiding quality degradation from distance or obstructions.
Solution Approach 2:
The patent introduces a wireless communication connection as an intermediary between the display device and the photographing device. This communication channel serves as a mediator to transfer display content data, replacing the direct optical path that would otherwise be blocked or degraded by physical constraints.
2Productivity
If the user uses the camera application to photograph display content, then the shooting function is utilized, but the operation becomes complex requiring connection establishment and mode switching
Solution Approach 1:
The patent merges the screen mirroring function with the camera application by integrating the mirroring control directly into the camera interface. The photographing device simultaneously performs camera preview and display content mirroring, combining multiple functions into a unified operation that eliminates the need for separate connection establishment and mode switching.
Solution Approach 2:
The patent establishes the wireless connection and initiates screen mirroring automatically when the camera application is launched or when display content is detected in the camera preview. This preliminary action removes the need for users to manually configure connection settings or switch modes during the photographing process.

AI summary
A photographing method and a terminal device are provided. The method includes: enabling, by a first terminal device, an image shooting function based on a first operation performed by a user, and obtaining and displaying a preview image; outputting, by the first terminal device, first prompt information based on the preview image if the preview image includes an image of an image output device, where the first prompt information is used to indicate, to the user, that the first terminal device can connect to a second terminal device, and the second terminal device is a device determined by the first terminal device based on feature information of the image output device; connecting, by the first terminal device, to the second terminal device in response to an operation of triggering the first prompt information; receiving, by the first terminal device, first image sent by the second terminal device, where the first image includes content currently played by an image output device of the second terminal device; and displaying, by the first terminal device, the first image. In this manner, content on a display can be clearly photographed, to improve a photographing effect and improve user experience.
