Stereo Camera Preset Modes for Interocular Distance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stereographic cameras require users to manually set complex parameters such as interocular distance and convergence angle, which can be challenging for inexperienced users and may not optimize image depth perception due to varying viewer and image-dependent disparity limits.
Innovation Solution
A stereographic camera system with preset modes that automatically set interocular distance, convergence angle, and other parameters based on predefined scenarios, allowing users to select from modes like portrait, interior, sport, and scenery, ensuring optimal 3D image capture by synchronizing lens focus, zoom, and disparity settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually set interocular distance and convergence angle parameters, then the camera can capture stereographic images, but the operation becomes complex and challenging for inexperienced users
Solution Approach 1:
The patent applies parameter changes by providing preset modes (portrait, landscape, sport, interior, exterior) that automatically configure optimal values for interocular distance, convergence angle, and other stereographic parameters based on the selected mode, eliminating the need for users to manually adjust complex parameters while maintaining image quality
Solution Approach 2:
The camera system performs self-service by automatically setting stereographic parameters when a preset mode is selected, with the controller autonomously configuring interocular distance, convergence angle, and other parameters without requiring user expertise, thereby simplifying operation while maintaining technical precision
2Manufacturing precision
If users manually adjust parameters to optimize depth perception, then image quality may improve, but user error increases and consistency decreases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing optimal parameter combinations for various shooting scenarios in preset modes. When a user selects a mode, the camera has already determined the best interocular distance, convergence angle, and other parameters for that specific situation, ensuring consistent and reliable results without requiring users to make potentially erroneous manual adjustments
3Adaptability or versatility
If the camera provides multiple adjustable parameters for different scenarios, then adaptability improves, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing preset modes that cover multiple shooting scenarios (portrait, landscape, sport, interior, exterior), each containing optimized parameter combinations. This allows a single camera system to adapt to various situations without requiring users to understand or adjust individual parameters, maintaining versatility while simplifying the user interface through unified preset selection

AI summary
A stereographic camera and a method of operating a stereographic camera are disclosed. The stereographic camera may include a left camera and a right camera having respective lenses and an interface for receiving a selection of a selected preset operating mode from a plurality of preset operating modes. A preset parameter memory may store a plurality of preset parameter sets, each of the plurality of preset parameter sets associated with a corresponding one of the plurality of preset operating modes, each of the plurality of preset parameters sets including an assumed minimum object distance and an assumed extreme object distance. An interocular distance mechanism may set an interocular distance between the left camera and the right camera based on, at least in part, the assumed minimum object distance and the assumed extreme object distance associated with the selected operating mode.
