Photo Display on Non-Standard Screens Using Focus Region Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face difficulties in optimizing the display of photos with specific shapes on screens of different shapes, often resulting in inefficient use of screen space and loss of important image information, particularly when a rectangular image is displayed on a circular screen.
Innovation Solution
A method and apparatus that extract photographing information from a digital photo file, such as lens and focal length data, to determine the intended focus region and adjust the image accordingly, ensuring optimal display on any shaped screen by either zooming or filling the screen with copied image portions to maintain important information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rectangular photo is displayed on a circular screen using traditional methods, then the screen shape compatibility is improved, but the image information completeness deteriorates
Solution Approach 1:
The patent segments the photo display process into multiple stages: extracting photographing information (lens type, focal length, focus position), determining the focus region, and selectively processing different parts of the image. This segmentation allows the system to preserve important focused regions while adapting to circular screen constraints.
Solution Approach 2:
The patent transitions from considering only the 2D rectangular image dimensions to incorporating the 3D optical parameters (focal length, aperture, focus distance) stored in the photo metadata. By utilizing this additional dimensional information, the system can intelligently determine the focus region and optimize display on circular screens without losing critical image content.
2Manufacturing precision
If a rectangular photo is inscribed in a circular screen, then the image quality is preserved, but the screen space utilization deteriorates
Solution Approach 1:
The patent applies local quality by differentiating between the focus region and non-focus regions of the photo. The focus region is extracted and prioritized for display, while non-critical areas are adapted or cropped to fit the circular screen. This selective processing maintains image quality in important areas while optimizing screen space utilization.
Solution Approach 2:
The system performs preliminary analysis of the photo metadata (lens information, focal length, focus position) before display to pre-determine the focus region. This preliminary action allows the system to optimize the display composition in advance, ensuring both image quality preservation and efficient screen space utilization on circular displays.
3Area of stationary object
If zooming is applied to fit a rectangular photo on a circular screen, then the screen coverage is improved, but the focus region accuracy deteriorates
Solution Approach 1:
The patent implements dynamic processing by adjusting the display parameters (zoom level, cropping region, positioning) based on the extracted focus information from photo metadata. The system dynamically determines the optimal display configuration that maintains focus region accuracy while achieving comprehensive screen coverage on circular displays.
