Image Cropping System for Spectator Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing systems struggle to provide images to multiple spectators efficiently, especially when the number of requested images exceeds the number of cameras, leading to issues with image data management and delayed provision, as well as difficulties in specifying and delivering images to target spectators, particularly in diverse spectator positions.
Innovation Solution
An image providing system that acquires user position information to determine a cropping range for image capture, applies cropping to captured images based on this range, and provides cropped images to users, incorporating face detection and matching to ensure accurate delivery of images to specific spectators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of cameras is increased to capture more spectator images, then the number of images that can be provided increases, but the system complexity and cost increase
Solution Approach 1:
The patent divides the spectator area into multiple zones with different capturing priorities. Instead of uniformly capturing all spectators, the system segments the audience and focuses resources on high-priority zones, allowing fewer cameras to serve more spectators effectively.
Solution Approach 2:
The patent applies different capturing strategies to different spectator zones based on their specific needs and positions. High-priority zones receive more attention and resources, while lower-priority zones use standard capturing, optimizing the overall system efficiency without uniformly increasing camera count.
2Productivity
If the capturing range is expanded to cover more spectators, then more images can be provided, but the image quality and specificity for individual spectators deteriorate
Solution Approach 1:
The patent dynamically adjusts the capturing range and priority levels based on real-time spectator distribution and demand. The system can shift resources between wide-area coverage and focused individual capture depending on current conditions, optimizing both productivity and image specificity.
Solution Approach 2:
The patent captures images at different quality levels and priorities. For some spectators, full-resolution detailed capture is performed, while for others, lower-resolution or less frequent capture is sufficient, allowing the system to serve more spectators with acceptable image quality without uniformly degrading specificity.
3Adaptability or versatility
If the image data amount is increased to satisfy all spectator demands, then all spectators can receive their requested images, but the image provision speed decreases
Solution Approach 1:
The patent implements continuous image capture and processing at different priority levels. High-priority images are processed and delivered continuously without waiting for lower-priority processing, ensuring fast provision for key spectators while maintaining overall system adaptability to diverse demands.
Solution Approach 2:
The patent applies different data processing and delivery priorities to different spectator groups. Critical images are processed with higher priority and delivered faster, while less critical images can be processed in the background, balancing adaptability with provision speed.
4Reliability
If the capturing interval is shortened to capture more frequent images, then the likelihood of capturing desired moments increases, but the image data processing time and system load increase
Solution Approach 1:
The patent implements periodic capturing with variable intervals based on priority and current conditions. High-priority zones may experience more frequent capture intervals, while lower-priority zones use longer intervals, reducing overall processing time while maintaining reliability for critical captures.
Data Source
AI summary
An image providing system capable of quickly providing a plurality of different cropped images is disclosed. The image providing system acquires position information about a position of a user designated by the user. The image providing system determines a range of an image that was captured by an image capturing unit, the range corresponding to the position information as a cropping range, before the image capturing unit starts a series of image capturing in which the image capturing unit captures a plurality of images. After the series of image capturing is started, the system applies cropping that cuts out a part of a captured image based on the cropping range. During the series of image capturing, the system provides a cropped image to which the cropping has been applied in a way in which a user can obtain the cropped image.
