Image-Shake Correction Apparatus with Feedback Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual systems, image-shake correction apparatuses for real cameras often result in unnatural synthesized images due to mismatched motions between actual and electronic video images, as the image-shake correction in real cameras reduces the effect of vibrations on the camera, leading to partial image shake in synthesized videos.
Innovation Solution
An image-shake correction apparatus that includes an image displacement device to cancel image shake by displacing images formed by the image-capturing optical system, with an output device providing information on image displacement to external apparatuses, allowing for processing that considers the image-shake correction, and can be integrated into or mounted as an auxiliary device with the lens unit, using either analogue or digital signals for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image-shake correction is applied in the real camera, then image shake is corrected, but the motion between actual and electronic video images does not coincide, resulting in unnatural synthesized images
Solution Approach 1:
The patent applies feedback by outputting image-shake correction information from the real camera to the external apparatus creating electronic video images. This feedback loop enables the external apparatus to adjust its image processing based on the actual correction applied to the real camera, ensuring synchronized motion between actual and electronic video images and eliminating the unnatural appearance in synthesized images.
2Reliability
If image displacement device is used to cancel image shake, then image stability is improved, but information synchronization with external apparatus is lost, causing motion mismatch
Solution Approach 1:
The patent uses an output device as an intermediary to transmit image-shake correction information from the real camera to the external apparatus. This intermediary ensures that the information about image displacement is preserved and communicated, allowing the external apparatus to synchronize its processing and maintain motion coherence in the synthesized image.
