Image Capture Control With Subject-Match Viewpoint Indexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capture systems require users to repeatedly switch between images from different user terminals to find a desired image-capturing position and direction, lacking an efficient method to identify and display images captured at optimal positions and directions.
Innovation Solution
An image capture apparatus and method that utilize pattern matching or subject recognition processing to determine if another image capture apparatus can capture a subject's range, displaying an index indicating the image-capturing direction and position based on obtained information, enabling direct selection of desired images without repeated switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users repeatedly switch between images from different user terminals to find a desired image, then the user can eventually find an image captured at a desirable position and direction, but the operation time and complexity increase significantly
Solution Approach 1:
The system performs preliminary analysis by obtaining image-capturing position and direction information from other image capture apparatuses before the user needs to select an image. Index information indicating whether the subject is within the capture range is prepared in advance and displayed on the current image, allowing users to make immediate informed decisions without repeatedly switching between images.
2Ease of operation
If the system displays index information about image-capturing position and direction, then the user can easily identify suitable images, but the information processing and pattern matching complexity increases
Solution Approach 1:
Instead of performing complex real-time pattern matching on the actual images, the system creates and processes simplified index information that represents the essential characteristics (capture position and direction). This index data serves as a copy or abstraction of the image metadata, enabling efficient comparison and display without the computational burden of analyzing full image content.

AI summary
An image capture apparatus performs control to display a subject image, receives an image captured by another other image capture apparatus, and determines whether or not the other image capture apparatus is capable of capturing an image of a range including the subject. When the other image capture apparatus is capable of capturing an image of the range including the subject, a control is performed to display, on the subject image, an index indicating the image-capturing direction at a location corresponding to the image-capturing position of the image, and the determination is performed by executing pattern matching processing or subject recognition processing on the subject image and the received image from the other image capture apparatus, and the other image capture apparatus is capable of capturing an image of the range including the subject if the subject matches a subject included in the received image.
