Background Video Alignment for Stabilized In-Camera VFX
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-camera VFX technologies fail to generate appropriate background video when image stabilization is activated in the camera, leading to unnatural motion mismatches between the background and real-world subject.
Innovation Solution
An image processing apparatus and method that detects the position and orientation of the camera with image stabilization enabled, correcting the detected motion to align with the image stabilization, thereby generating a synchronized background video.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If image stabilization function is activated in the camera, then image blur in live-action video is reduced, but the background video becomes misaligned with the real-world subject
Solution Approach 1:
The system continuously detects the camera's position and orientation, receives image stabilization correction information from the camera, and uses this feedback to dynamically adjust the background video's position and orientation, ensuring continuous alignment between the background and the real-world subject despite camera motion stabilization
Solution Approach 2:
The image processing apparatus acts as an intermediary between the camera and the display apparatus, receiving detection information from the camera, processing it through position and orientation detection and correction, and generating corrected background video that is then displayed in sync with the stabilized live-action footage
2Reliability
If image stabilization is effective, then motion in the captured video is corrected, but the detected camera position and orientation do not reflect the actual visual output
Solution Approach 1:
The system applies preliminary correction to the detected position and orientation data by incorporating image stabilization correction information before generating the background video, preventing the mismatch between detected camera position and actual visual output from occurring in the first place

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