Background Video Synchronization for Stabilized In-Camera VFX
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-camera VFX video systems fail to generate appropriate background video when the image stabilization function of the camera is activated, leading to unnatural motion between the background and real-world subject due to camera shake.
Innovation Solution
An image processing apparatus and method that utilizes a viewpoint detection system to continuously detect the camera's position and orientation, correcting for image stabilization effects, and generates synchronized background video to match the live-action footage, ensuring smooth integration in VFX video production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the image stabilization function is activated to reduce image blur, then image stability is improved, but the background video becomes unsynchronized with the live-action video due to camera shake correction
Solution Approach 1:
The system uses viewpoint detection to continuously monitor camera position and orientation, then feeds this information back to adjust the background video display. By detecting the actual camera viewpoint and using this feedback to synchronize the background video with the stabilized live-action footage, the system resolves the contradiction between image stabilization and background synchronization.
Solution Approach 2:
The patent introduces a viewpoint detection apparatus as an intermediary between the camera and the background video generation system. This intermediary detects camera shake and viewpoint changes, enabling the background video to be adjusted accordingly to match the stabilized live-action video, thus resolving the synchronization issue.
2Ease of operation
If the camera is made movable to enable flexible shooting, then ease of operation is improved, but image blur increases due to camera motion
Solution Approach 1:
The viewpoint detection system continuously monitors camera motion and provides feedback information about position and orientation changes. This feedback enables real-time adjustment of the background video to match the movable camera's viewpoint, allowing flexible shooting while maintaining image stability through electronic stabilization.
Solution Approach 2:
The patent replaces the need for mechanical stabilization systems (tripods, cranes) with an electronic solution. By using viewpoint detection and digital processing to compensate for camera motion, the system enables flexible handheld operation while maintaining image stability, substituting mechanical constraints with electronic stabilization.
3Stability of the object's composition
If the camera is fixed to eliminate image blur, then image stability is improved, but adaptability of shooting positions and angles is reduced
Solution Approach 1:
The patent replaces fixed mechanical mounting systems with an electronic stabilization approach. By detecting camera viewpoint changes and digitally adjusting the background video accordingly, the system enables flexible shooting positions and angles while maintaining image stability, eliminating the need for fixed camera mounts.
Solution Approach 2:
The viewpoint detection and background synchronization system provides universal applicability across various shooting scenarios. Whether the camera is handheld, mounted on a stabilizer, or positioned differently, the system adapts to maintain synchronization, making the solution versatile for different shooting configurations.

AI summary
An image processing apparatus (130, 110) detects a position and orientation of an image capture apparatus (200) that captures an image of a subject with a video displayed on a display apparatus (310) as a background and generates a video to be displayed on the display apparatus (310) in accordance with the detected position and orientation. In a case where image stabilization in the image capture apparatus (200) is effective, the apparatus corrects the detected position and orientation such that motion in the video displayed on the display apparatus (310) reflects the image stabilization.
