Dynamic Chroma Key Viewpoint Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chroma key image generation technologies fail to provide an immersive feeling as if a subject actually exists in a space, as they simply overlay a subject onto a background without considering the camera's position and pose, resulting in a lack of realism and depth.
Innovation Solution
A dynamic image capturing apparatus using arbitrary viewpoint image generation technology, which calculates the camera's position and pose relative to the subject and generates background content at a matching viewpoint, allowing the camera to capture images that create a realistic and immersive experience by synchronizing the subject's and background's views, even when the camera moves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If chroma key image generation technology is used to overlay subject onto background, then image generation speed is improved, but immersion and realism are worsened
Solution Approach 1:
The patent applies dynamics by making the background content adaptive to camera movements. The system dynamically adjusts the background viewpoint based on detected camera position and orientation changes, transforming a static background overlay process into a dynamic one that maintains realism during camera motion. This resolves the contradiction by enabling real-time background adjustment without sacrificing generation speed.
Solution Approach 2:
The patent changes key parameters including camera position coordinates, pose angles, and background viewpoint parameters. By detecting camera movement parameters and correspondingly adjusting background content parameters, the system maintains the chroma key processing speed while improving realism through parameter synchronization between subject and background.
2Device complexity
If simple chroma key overlay is used, then device complexity is reduced, but immersion feeling is worsened
Solution Approach 1:
The system implements self-service by automatically detecting camera movements and autonomously adjusting background content without requiring manual intervention. The apparatus self-corrects viewpoint mismatches by processing camera position data and correspondingly transforming background images, maintaining simplicity while enhancing immersion through automated adaptation.
Solution Approach 2:
The patent incorporates feedback mechanisms where camera movement detection results are fed back to the background processing module. This closed-loop system uses detected camera position and orientation information to continuously adjust background viewpoint, creating a feedback-driven adaptation process that enhances realism without significantly increasing system complexity.
3Loss of time
If background content is not adjusted for camera movement, then processing time is reduced, but viewpoint matching and realism are worsened
Solution Approach 1:
The system applies preliminary action by pre-establishing the relationship between camera parameters and background viewpoint parameters. Detection algorithms are pre-configured to recognize camera movement patterns, and background adjustment transformations are pre-computed based on detected motion, enabling rapid real-time adaptation without extensive processing delays.

AI summary
Embodiments relate to a dynamic image capturing method and apparatus using an arbitrary viewpoint image generation technology, in which an image of background content displayed on a background content display unit or an image of background content implemented in a virtual space through a chroma key screen, having a view matching to a view of seeing a subject at a viewpoint of a camera is generated, and a final image including the image of the background content and a subject area is obtained.
