Projected Video Expansion Timing for Overlap-Free External Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices struggle to efficiently synchronize and expand video content displayed on an external device while preventing overlap and distortion, particularly when adjusting the size and position of the projected image.
Innovation Solution
An electronic device equipped with a communication circuit, projection assembly, processor, and memory, which executes instructions to obtain and scan video information, identify time for expansion, provide notifications, and display a partially overlapping black area to adjust the projected image size and position, using a projection assembly.

Engineering Contradiction Analysis
1Area of stationary object
If video content is expanded to provide a wider viewing experience, then the viewing area is improved, but the risk of overlap and distortion with the external device increases
Solution Approach 1:
The system performs preliminary actions by scanning the first video content and calculating the required time before actually projecting the expanded second video. This advance preparation allows the system to coordinate the projection timing with the external device's display schedule, preventing overlap and distortion while maximizing the viewing area.
Solution Approach 2:
The system dynamically adjusts the projection timing based on the calculated time requirement. By making the projection start time variable rather than fixed, the system can adapt to different video lengths and external device display schedules, ensuring precise positioning without overlap while maintaining an expanded viewing area.
2Manufacturing precision
If the projected image size is adjusted to avoid overlap with external device, then the positioning accuracy is improved, but the viewing area is reduced
Solution Approach 1:
The system resolves the conflict between positioning accuracy and viewing area by introducing a temporal dimension. Instead of only adjusting spatial position, the system uses time coordination - calculating how long the first video needs to be displayed before expanding to the second video. This temporal adjustment allows the projected image to start at an optimized position that avoids overlap while maintaining maximum viewing area.
3Productivity
If video expansion is performed to enhance viewing experience, then the productivity is improved, but the time required for processing increases
Solution Approach 1:
The system implements feedback by scanning the first video content to determine its characteristics and calculating the appropriate time requirement for expansion. This feedback loop allows the system to optimize the processing time based on actual video content rather than using fixed or excessive processing time, thereby improving productivity while minimizing time loss.
