Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stereoscopic imaging technologies face challenges in effectively presenting three-dimensional images, particularly in achieving optimal depth perception due to limitations in interocular distance and convergence angle adjustments, which can result in excessive disparity leading to two-dimensional image perception rather than true 3D imagery.
Innovation Solution
The integration of a 3D camera system with adjustable interocular distance and stereo convergence angle, coupled with a 2D camera, allows for synchronized focus and focal length adjustments to optimize the presentation of stereographic images, ensuring accurate depth perception by aligning the inter-camera convergence angle with the focus distance and setting the stereo convergence distance proportionally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the interocular distance is increased to enhance depth perception, then the apparent depth of the stereographic image is improved, but the disparity between left and right images becomes excessive causing the images to be perceived as two overlapping 2D images rather than true 3D imagery
Solution Approach 1:
The patent implements dynamic adjustment of the interocular distance between the left and right cameras, allowing the distance to be modified during operation based on the subject matter being filmed. This enables the system to optimize depth perception for different scenarios without being locked into a fixed configuration, thereby avoiding excessive disparity while maintaining accurate depth cues.
Solution Approach 2:
The system changes the interocular distance parameter adaptively rather than using a fixed value. By adjusting this critical parameter based on the specific filming requirements and subject distance, the patent achieves optimal depth perception accuracy while preventing the harmful effect of excessive image disparity that would degrade 3D quality.
2Measurement precision
If the convergence angle is adjusted to match the interocular distance for optimal 3D perception, then the stereo convergence distance is improved, but the device complexity increases due to the need for synchronized adjustments of multiple parameters
Solution Approach 1:
The patent incorporates feedback mechanisms that automatically adjust the convergence angle based on the set interocular distance and focus parameters. The system continuously monitors the relationship between these parameters and makes real-time corrections to maintain proper stereo convergence, eliminating the need for manual synchronization and reducing operational complexity.
Solution Approach 2:
The camera system performs self-adjustment of the convergence angle automatically when the interocular distance or focus is changed. This self-service capability ensures that the stereo convergence distance remains accurate without requiring external intervention or complex manual coordination of multiple parameters, thereby reducing device complexity.
3Ease of operation
If fixed interocular distance and convergence angle are used to simplify device operation, then the ease of operation is improved, but the adaptability to different shooting scenarios and depth requirements is reduced
Solution Approach 1:
The patent transforms the fixed interocular distance and convergence angle into dynamically adjustable parameters. This allows the camera to adapt to different shooting scenarios, subject distances, and depth requirements while maintaining simple operation through automated control systems that handle the complexity of adjustments.
Solution Approach 2:
The camera system is designed with multi-functionality to handle various shooting scenarios effectively. By incorporating adjustable interocular distance and convergence angle capabilities, the single camera unit can serve multiple purposes - from close-up shots requiring larger interocular distances to distant shots requiring smaller distances - thereby achieving universality without sacrificing ease of operation.

AI summary
An integrated 2D/3D camera system may include a 2D camera and a 3D camera affixed to the 2D camera. The 2D camera may include a first lens that is lens adjustable to set a 2D focus distance. The 3D camera may include a left camera and a right camera including respective left and right lenses, the left and right lenses synchronously adjustable to set a 3D focus distance. A focus mechanism may automatically set the 2D focus distance and the 3D focus distance to be essentially equal by one of adjusting the first lens based on the 3D focus distance and synchronously adjusting the left and right lenses based on the 2D focus distance.
