Stereo Camera Image Matching via Symmetrical Scrolling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital stereo cameras and 3D cinema systems lack effective means for accurate matching adjustment of left and right images, leading to reduced stereoscopic effects and visual fatigue, especially during photography and printing processes.
Innovation Solution
A digital stereo camera with paired photographing optical systems, electronic displays, and a manual scrolling unit that allows for symmetrical horizontal scrolling of images to adjust the spacing between left and right image display regions, enabling optimal stereoscopic image capture and printing with improved matching adjustment capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional digital stereo cameras use fixed image display regions, then the device structure is simple, but accurate matching adjustment of left and right images cannot be achieved
Solution Approach 1:
The patent applies the dynamics principle by making the image display regions movable rather than fixed. The left and right image display regions can be scrolled horizontally to adjust their spacing, allowing dynamic matching adjustment. This resolves the contradiction by enabling precise matching control while maintaining a relatively simple device structure through software-controlled display manipulation.
2Measurement precision
If manual scrolling is added to adjust image spacing, then matching adjustment capability is improved, but ease of operation is reduced
Solution Approach 1:
The patent applies feedback by providing real-time visual display of the scrolling effect on the liquid crystal display device. Users can observe the changing spacing between left and right images as they scroll, allowing them to achieve accurate matching adjustment while maintaining operational simplicity through intuitive visual feedback.
3Manufacturing precision
If aspect ratios of image display areas are narrowed for masking, then stereoscopic image quality is improved, but loss of information increases
Solution Approach 1:
The patent applies local quality by selectively masking only the peripheral portions of images that would cause stereoscopic discomfort, while preserving the central important image content. The aspect ratio narrowing is applied locally to the display region rather than to the entire captured image, maintaining high stereoscopic image quality while minimizing information loss.

AI summary
A matching adjustment between left and right screens is easily and accurately performed in a digital stereo camera and/or a digital stereo video camera at or after the time of photographing. A stereo viewfinder 3 of a digital stereo camera 1 comprises a pair of left and right liquid crystal displays and eyepiece lenses 10. Aspect ratios of left and right image display regions of the liquid crystal displays is made narrower than aspect ratios of image capture regions of image capture devices and horizontal scrolling is performed symmetrically. Images on the image capture devices are horizontally scrolled, while finder images are viewed in a stereoscopic manner with both eyes, so that perspective of a stereoscopic image changes and an optimally scrolled image data can be photographed. Scroll adjustment can be performed on image data after being photographed, and stereo photographs giving an optimal stereoscopic feeling can be printed from edited image data.
