Cross-Device Color Mode Synchronization for Seamless Screen Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When mobile devices and display devices have different color modes, screen switching can be abrupt, affecting the user experience, and users must manually change color modes to update display contents.
Innovation Solution
A control method that involves obtaining a second parameter representing the color mode of a second device through a transmission channel, rendering the display content of a first application based on this color mode, and sending it to the second device to ensure a consistent visual effect with the second device's display content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the color modes of mobile devices and display devices are different, then the screen switching is abrupt, but the user viewing experience is affected
Solution Approach 1:
The system obtains the color mode parameter of the display device through the transmission channel and uses this feedback information to adjust the rendering of display content on the mobile device, ensuring color mode consistency between devices and eliminating abrupt screen switching
Solution Approach 2:
The system changes the color mode parameter of the display content based on the obtained color mode parameter of the display device, transforming the content to match the target display device's color mode and achieving seamless transitions
2Stability of the object's composition
If the color modes are manually changed to update display contents, then the visual effect consistency is achieved, but the operation complexity increases
Solution Approach 1:
The system automatically obtains the color mode parameter of the display device and adjusts the display content rendering without requiring manual user intervention, enabling the system to self-regulate and maintain visual effect consistency
Solution Approach 2:
The system performs preliminary action by obtaining the color mode parameter before rendering the display content, ensuring that the content is pre-adjusted to match the display device's color mode, thereby avoiding the need for manual changes later

AI summary
A control method includes obtaining a second parameter through a transmission channel, obtaining a first application, the first application belonging to a first device, rendering a display content of the first application in a running status based on the color mode represented by the second parameter, and sending the display content through the transmission channel to the second device, so that a visual effect of the display content on the second device is consistent with a visual effect of a display content of a second application displayed on the second device. The transmission channel is a channel established with a second device. The second parameter represents a color mode of the second device. The color mode at least indicates a foreground color and a background color of an application. The foreground color contrasts with the background color.
