Spherical Video Partial Area Display for Digest Reproduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies fail to effectively display important portions of spherical video images captured during movements, such as walking or traveling, as they do not account for the direction and importance of captured items within the frame, making it difficult for users to recognize key objects in digest reproductions.
Innovation Solution
A content provision system that includes an information processing apparatus and terminal device, which retrieves and transmits content images along with position information to display specific areas of interest based on designated points, allowing the terminal device to reproduce the content by selecting and displaying partial areas of images from capturing locations closest to these points, ensuring that important objects are highlighted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a spherical image is captured to include all objects in the scene, then the coverage of the scene is improved, but the ability to display important objects clearly is worsened because the entire spherical image cannot be displayed at once
Solution Approach 1:
The spherical image is divided into multiple planar images captured at different capturing locations. Each planar image covers a specific directional view, and the system segments the display into multiple display areas, each showing a relevant planar image. This segmentation allows important objects in different directions to be displayed simultaneously without requiring the entire spherical image to be shown at once.
Solution Approach 2:
The system transitions from displaying a single spherical image to displaying multiple planar images arranged in a multi-area layout. By converting the three-dimensional spherical image into two-dimensional planar representations that can be arranged spatially on the display screen, the system enables simultaneous visualization of important objects from different directions while maintaining clear visibility.
2Loss of information
If the entire spherical image is displayed, then complete scene information is provided, but important objects may not be recognizable because they are scattered across different directions
Solution Approach 1:
Different display areas are assigned different qualities based on their importance. The system identifies important objects and their capturing locations, then allocates specific display areas to show planar images containing these important objects. This local quality approach ensures that important objects receive focused attention in dedicated display regions rather than being lost in the overall spherical image.
Solution Approach 2:
The system performs preliminary identification of important objects and their locations before display. By pre-determining which objects are important and which capturing locations contain them, the system can proactively arrange the planar images in optimal display areas, ensuring important objects are immediately recognizable without requiring users to search through the entire spherical image.
3Loss of time
If digest reproduction is applied to summarize video images, then the reproduction time is reduced, but the ability to show important portions clearly is worsened because conventional methods do not consider frame portions
Solution Approach 1:
The digest reproduction selectively displays important portions of video frames rather than showing entire frames. By identifying important objects and their locations within frames, the system extracts and displays only the relevant portions in appropriate display areas, maintaining clarity of important items while reducing overall reproduction time by omitting less important content.
Solution Approach 2:
The system extracts important objects and their surrounding context from the original video frames, separating them from the rest of the frame content. These extracted important portions are then displayed in dedicated display areas during digest reproduction, ensuring that key information is preserved and highlighted while the less important portions are omitted to achieve time compression.
