Shooting Method Region Marker Video Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices have limited shooting modes and cannot effectively capture videos with the desired visual effect, leading to poor user experience due to inability to focus on specific objects and adjust video capture regions.
Innovation Solution
A shooting method that acquires multiple image frames, displays them with a marker indicating the video capture region, and generates a video from the images within that region, allowing users to focus on specific objects and adjust the video capture area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the camera captures the entire scene, then the field of view is maximized, but the focus on specific objects is lost
Solution Approach 1:
The patent divides the entire scene into multiple regions by displaying a grid overlay on the preview interface. Users can select specific regions (e.g., region of interest) for focused capture while other regions are captured with reduced detail. This segmentation allows the system to allocate processing resources selectively, maintaining high focus precision on chosen objects while preserving overall scene context.
Solution Approach 2:
The patent applies different quality levels to different regions of the captured scene. The selected region of interest is captured with high resolution and sharp focus, while surrounding areas are captured with lower resolution or adjusted focus. This local quality differentiation enables the system to emphasize specific objects without completely sacrificing the broader scene context.
2Adaptability or versatility
If multiple shooting modes are provided, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal region selection mechanism that works across different shooting scenarios (portraits, landscapes, close-ups, etc.). The same grid-based region selection interface and processing pipeline are used regardless of the specific shooting mode, allowing one system to handle multiple functions. This reduces the need for separate complex processing paths for each shooting mode while maintaining versatility.
Solution Approach 2:
The patent provides dynamic region selection where users can adjust the region of interest in real-time during preview, and the system dynamically adjusts the capture parameters accordingly. The grid overlay and region boundaries are not fixed but can be moved, resized, and reconfigured based on user input and scene conditions, enabling flexible adaptation without requiring pre-configured fixed modes.
3Measurement precision
If the video capture region is manually adjusted, then the focus on desired objects is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent implements automatic region detection and suggestion features that analyze the preview scene to identify potential regions of interest (e.g., detecting faces, objects, or areas with significant visual features). The system automatically proposes region boundaries or highlights suggested capture areas, reducing the manual adjustment burden. Users can accept these automatic suggestions with a simple gesture or modify them minimally, combining automated intelligence with user control.
Solution Approach 2:
The patent provides real-time visual feedback during the region selection process. As users adjust the grid or drag region boundaries, the system immediately shows how the selected region will be captured and processed, allowing users to see the effect of their adjustments before finalizing. This immediate feedback loop helps users make informed adjustments more efficiently without requiring multiple trial-and-error attempts.
