Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D video shooting techniques face issues such as misaligned parallax due to head inclination, large camera systems, and blind spots, which hinder the acquisition of appropriate parallax and image quality.
Innovation Solution
An imaging apparatus with a first imaging section and multiple smaller second imaging sections, combined with an image processing section to generate data from the captured images, allowing for improved 3D video production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two cameras are increased in optical size to achieve higher image quality, then image quality is improved, but camera system size increases
Solution Approach 1:
The imaging system is segmented into one large first imaging section for high-quality central imaging and multiple smaller second imaging sections for peripheral imaging. This segmentation allows the system to achieve high image quality where needed while keeping the overall camera system size compact by using smaller sensors for the remaining fields of view.
Solution Approach 2:
The patent merges the imaging functions of multiple cameras into a single integrated system where the first and second imaging sections work together. The image processing section combines images from both imaging sections, allowing the system to achieve high image quality equivalent to large cameras while maintaining a compact form factor through coordinated operation of smaller components.
2Measurement precision
If two cameras are increased in optical size to achieve higher image quality, then image quality is improved, but blind spots occur at proximity distance between the lenses
Solution Approach 1:
The imaging system is segmented into one large first imaging section for high-quality central imaging and multiple smaller second imaging sections for peripheral imaging. This segmentation allows the system to achieve high image quality where needed while keeping the overall camera system size compact by using smaller sensors for the remaining fields of views.
Solution Approach 2:
The patent employs an asymmetric arrangement where a single large first imaging section is positioned centrally and multiple smaller second imaging sections are positioned at different locations around it. This asymmetric configuration optimizes the imaging coverage to eliminate blind spots at proximity distances while maintaining high image quality in the central region where the large sensor provides superior performance.
3Adaptability or versatility
If conventional two-camera arrangement is used for 3D video, then parallax can be captured, but appropriate parallax cannot be acquired when user's head is inclined
Solution Approach 1:
The imaging system is designed with multi-functionality to serve multiple viewing conditions. The first imaging section provides high-quality central images while the multiple second imaging sections capture peripheral views from different angles. This universal configuration allows the system to maintain appropriate parallax relationships regardless of whether the user's head is upright or inclined, as the multiple imaging sections collectively provide the necessary viewpoint information for various head orientations.
