Solid-State Imaging Element Stereo Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stereo imaging devices with independent left and right cameras struggle to accurately fix the positional relationship between images, leading to inaccuracies in three-dimensional image capture due to tilts and positional deviations.
Innovation Solution
The solution involves imaging each image light from a subject at different positions of a single lens means as multiple images in various regions of a solid-state imaging element, eliminating the need for correcting tilts and positional deviations by separating left and right image lights into distinct regions on a single imaging element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two independent cameras are placed on the left and right to capture stereoscopic images, then stereoscopic imaging capability is achieved, but the positional relationship between left and right images cannot be accurately fixed due to tilts and positional deviations
Solution Approach 1:
The patent merges the functions of two independent cameras into a single camera by using a single imaging element with multiple imaging regions. This integration eliminates the positional deviations and tilts that occur between separate cameras while maintaining stereoscopic imaging capability through directional sensitivity differences in the merged structure.
Solution Approach 2:
The imaging element is segmented into multiple imaging regions, each with different directional sensitivities. This segmentation allows each region to capture images from specific directions, enabling accurate stereoscopic imaging by dividing the imaging function across specialized regions rather than using separate cameras.
2Adaptability or versatility
If two independent cameras are used for stereoscopic imaging, then left and right image capture is achieved, but correction means for tilts and positional deviations are required
Solution Approach 1:
The patent combines the stereoscopic imaging function and the correction function into a single integrated structure. By merging the two camera functions into one imaging element with directionally sensitive regions, the need for separate correction mechanisms is eliminated as the positional relationship is inherently fixed by the single structure.
3Volume of moving object
If two independent cameras are placed close together to reduce size, then device compactness is improved, but accurate fixing of positional relationship becomes even more difficult
Solution Approach 1:
The patent merges two camera systems into one, which naturally reduces the overall device size while eliminating the need for precise positioning between separate cameras. The single imaging element structure inherently maintains accurate positional relationships without requiring high-precision mounting of multiple components.

Function Achieved in This Case
