Electronic Device Camera Boundary Marker Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with cameras face challenges in capturing image data that includes additional information beyond a single image frame, particularly when dealing with display content and background scenes, as existing image sensors may not be able to capture a full image at one exact point in time, leading to incomplete data retrieval.
Innovation Solution
The method involves an electronic device capturing image data using a camera with an image sensor, where the device adjusts its field of view and lens position to include both display content and background scenes, and uses boundary markers embedded in the display content to determine and modify the image data, allowing for the generation of a complete image frame by combining multiple frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the image sensor captures a full pixel array at a single point in time, then the frame rate is maintained, but the captured image frame does not include additional information for subsequent handling of the captured image data
Solution Approach 1:
The patent segments the image capture process into multiple sequential captures of different regions (display content region and background scene region) rather than attempting to capture the entire field of view simultaneously. This allows comprehensive information collection while maintaining acceptable frame rates by processing regions separately.
Solution Approach 2:
The patent performs preliminary action by capturing the display content region first, then using that information to guide subsequent capture of the background scene region. This sequential approach ensures that boundary markers are identified and used to determine the extent of background capture needed, preventing information loss while optimizing the capture process.
2Loss of information
If the electronic device adjusts field of view and lens position to include both display content and background scenes, then complete image data is captured, but the device complexity increases
Solution Approach 1:
The electronic device performs self-service by using its own captured image data to identify boundary markers and automatically determine the extent of background scene capture needed. The processor analyzes the captured frames, detects boundary markers, and autonomously adjusts subsequent capture parameters without external intervention, reducing operational complexity.
Solution Approach 2:
The patent implements feedback by using the captured display content and identified boundary markers to inform and adjust the subsequent background scene capture process. The system continuously monitors captured data, identifies boundaries, and uses this information to optimize future capture operations, creating a closed-loop system that reduces complexity through intelligent adaptation.
3Productivity
If the image sensor cannot capture a full image at once, then the frame rate is maintained, but incomplete data retrieval occurs
Solution Approach 1:
The patent maintains continuity of useful action by seamlessly transitioning between capturing the display content region and the background scene region. Rather than interrupting the capture process, the system continuously accumulates useful image data across multiple sequential captures, ensuring complete data retrieval while maintaining high frame rates through efficient processing.
Solution Approach 2:
The patent applies dynamics by making the capture process adaptive and flexible. The system dynamically adjusts the capture sequence based on identified boundary markers, optimizing the balance between frame rate and data completeness. This dynamic approach allows the system to respond to different scene configurations while maintaining efficient operation.

Function Achieved in This Case
This approach enables the electronic device to capture and process image data that includes both display content and background scenes effectively, providing a complete and accurate representation of the field of view, even when the image sensor cannot capture a full image at once, by using boundary markers to define the image boundaries and modify the data accordingly.
