Server-Mediated Screenshot Acquisition for Smart Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for acquiring images from smart devices, such as smart TVs, are inefficient and lack a streamlined process for users to timely capture and store desired images.
Innovation Solution
A method and apparatus that detect a screenshot signal, send a request to a server with user account and target device identification, and receive a screenshot image from the server, enabling efficient image acquisition by the smart device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a user manually uses a camera or mobile phone to take a picture on a smart TV, then the user can obtain a desired image, but the process is time-consuming and lacks automation
Solution Approach 1:
The system enables self-service by allowing the smart device to automatically capture screenshots and transfer images to the terminal device without requiring manual camera operation. The terminal device sends screenshot requests that are automatically processed by the smart device, eliminating the need for users to manually operate cameras or mobile phones to capture images from the smart TV screen.
2Speed
If the system implements automatic screenshot functionality through server-mediated communication, then image acquisition speed improves, but system complexity increases
Solution Approach 1:
The server acts as an intermediary that mediates communication between the terminal device and the smart device. The terminal device sends screenshot requests containing device identification information to the server, which then forwards these requests to the appropriate smart device and relays the captured images back to the terminal device. This intermediary approach streamlines the communication process and improves screenshot acquisition speed while managing system complexity through centralized coordination.

AI summary
An image acquiring method includes: detecting whether a screenshot signal is triggered; sending a screenshot request to a server when the screenshot signal is triggered, the screenshot request including a user account and a target smart device identification, so as to enable the server to send the screenshot request to a target smart device based on the user account and the target smart device identification; and receiving a screenshot image from the server, the screenshot image being obtained by using the target smart device to perform a screenshot on an image displayed on the target smart device based on the screenshot request.
