Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image-capture control technologies focus on improving tracking accuracy but fall short in enhancing the immersive feeling required for capturing events like music live shows.
Innovation Solution
An information processing device that performs image-capture control based on image-capture rendering information and target information, allowing for selective control of real and virtual cameras, including pan, tilt, and zoom, to enhance the immersive experience by focusing on specific subjects or positions, and providing user-friendly selection and display controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image-capture control emphasizes tracking accuracy improvement, then control precision is improved, but immersive feeling is insufficient
Solution Approach 1:
The patent applies dynamics by enabling the camera to perform not only accurate tracking of subjects but also dynamic movements such as panning, tilting, and zooming based on rendering information. This allows the system to adapt between precise subject following and immersive cinematic movements, resolving the contradiction between tracking accuracy and immersive feeling.
Solution Approach 2:
The system changes multiple camera parameters simultaneously including orientation angles (pan, tilt), zoom level, and focal length based on rendering information. By dynamically adjusting these parameters, the system can switch between accurate subject tracking and immersive viewing experiences, thereby resolving the contradiction between measurement precision and adaptability.
2Adaptability or versatility
If multiple cameras are controlled with rendering information, then immersive experience is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal control system that can manage multiple cameras (both real and virtual) using the same rendering information and control logic. This multi-functional approach allows the system to coordinate various cameras for different purposes (tracking, panning, zooming) without requiring separate complex control mechanisms for each camera, thus improving immersive experience while controlling system complexity.
Solution Approach 2:
The system merges the control of multiple cameras into a unified control framework that processes rendering information centrally. By combining the control logic and using shared rendering data, the system achieves coordinated multi-camera operation for immersive experiences without proportionally increasing control system complexity.
3Measurement precision
If camera orientation is controlled to track subject, then subject tracking is improved, but angle of view control is compromised
Solution Approach 1:
The patent segments the camera control into independent components: orientation control for subject tracking and zoom control for angle of view management. By separating these control functions, the system can accurately track subjects through orientation adjustment while simultaneously maintaining precise angle of view control through independent zoom operations, resolving the contradiction between tracking precision and angle of view control.
Solution Approach 2:
The system adds the zoom dimension to the traditional orientation-based tracking approach. While orientation controls the direction of the camera for subject tracking, the zoom function independently controls the angle of view. This dimensional addition allows both subject tracking accuracy and angle of view precision to be maintained simultaneously.

AI summary
There is provided an information processing device that includes a control unit configured to perform image-capture control on the basis of image-capture rendering information indicating a change in captured image and image-capture target information indicating an image-capture target. The term “image-capture” used herein means an operation for obtaining an image using a camera, the “camera” being defined as both a real camera and a virtual camera that virtually changes composition by clipping a part of an image obtained as a result of a light-receiving operation of the real camera.
