Multi-View Image Distribution With Camera Attention Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In volumetric capture systems, subjects have difficulty identifying which camera is capturing their on-air image when multiple viewers can view images from different desired viewpoints, making it challenging to determine the appropriate camera to focus on.
Innovation Solution
An image distribution apparatus calculates a degree of attention for each image capture apparatus based on viewed image information from display apparatuses and transmits notification control information to notification units on the cameras to guide the subject's gaze.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cameras capture images from different directions for volumetric capture, then viewers can view images from desired viewpoints, but subjects cannot easily identify which camera to gaze at
Solution Approach 1:
The system implements feedback by transmitting viewed image information from display apparatuses back to the image distribution apparatus, which then calculates attention degrees and sends notification control information to the image capture apparatus. This closed-loop feedback mechanism enables real-time notification to subjects about which camera is currently capturing their image, allowing them to identify the active camera while maintaining multi-viewpoint flexibility.
Solution Approach 2:
The notification unit on each image capture apparatus uses color changes (or illumination changes) to indicate the attention degree and operational status of the camera. When a camera is actively capturing an image being viewed, its notification unit displays a specific color or illumination state, making it easily identifiable to the subject without restricting viewpoint options.
2Ease of operation
If a single on-air image is uniquely determined by a distributor, then subjects can identify the active camera using tally lamps, but multiple viewers cannot view images from different desired viewpoints simultaneously
Solution Approach 1:
The system dynamically adapts the notification control based on real-time viewing conditions. Instead of a fixed single-camera approach, the notification information changes dynamically according to which cameras are currently being viewed and their attention degrees, allowing multiple viewpoints to be active simultaneously while still providing clear identification through dynamic notification updates.
Solution Approach 2:
The system segments the notification function by providing individual notification control information to each image capture apparatus based on its specific attention degree. This allows each camera to independently display its own notification status, enabling multiple cameras to be identified simultaneously rather than requiring a single unified notification system.
3Loss of information
If notification is provided to all image capture apparatuses equally, then all cameras are identified, but the subject cannot distinguish which camera is most relevant to their attention
Solution Approach 1:
The notification control information incorporates local quality by varying the notification characteristics (such as brightness, color, or intensity) according to the attention degree of each specific camera. Cameras with higher attention degrees receive enhanced notification signals, allowing subjects to quickly identify which camera is most relevant while still having access to information about all cameras.
Solution Approach 2:
The system changes notification parameters (such as illumination intensity, color hue, or blinking patterns) based on the calculated attention degree for each camera. This parameter variation enables subjects to distinguish between cameras with different levels of relevance, with the most attention-worthy camera displaying the most prominent notification characteristics.

AI summary
An image distribution apparatus obtains a plurality of images generated by a plurality of image capture apparatuses capturing images of a predetermined subject from different directions, transmits the plurality of images to the plurality of display apparatuses, receives, from the plurality of display apparatuses, viewed image information regarding an image being displayed/reproduced in the plurality of display apparatuses, calculates a degree of attention for each of the image capture apparatuses capturing the images, based on the viewed image information, and transmits, to each of the image capture apparatuses, notification control information for causing a notification unit of the image capture apparatus, the notification unit being disposed in the same orientation as a lens unit of the image capture apparatus, to give notification based on the degree of attention.
