Stereoscopic Imaging Device Matching Optical Properties
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stereoscopic imaging devices with cameras of different properties cause excessive fatigue for observers due to the need to process images with varying optical properties, brightness, and stereo perspectives, which can lead to difficulties in fusing disparate visual information, especially for observers with different visual acuities.
Innovation Solution
A stereoscopic imaging device with at least two image recording units and an image processing unit that supplements original images with matching optical properties such as depth of field and resolution, generating displayed images that are balanced for both eyes, reducing the burden on the observer's brain to fuse these images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If original images with different optical properties are delivered to left and right eyes, then depth of field and resolution are improved in individual channels, but observer fatigue increases due to the need to process images with varying optical properties
Solution Approach 1:
The patent applies homogeneity by ensuring that both the left and right original images have identical optical properties, including the same depth of field and resolution. This is achieved by using matching optical systems in both channels, which eliminates the need for the observer's brain to process images with varying optical properties, thereby reducing observer fatigue while maintaining high image quality.
2Measurement precision
If different stop settings are used in left and right stereo channels, then optical resolution and depth of field are increased in individual channels, but the combination of images becomes taxing for the observer's brain
Solution Approach 1:
The patent applies homogeneity by using identical stop settings and optical configurations in both left and right stereo channels. This ensures that the optical resolution and depth of field are matched between channels, eliminating the need for complex image processing to reconcile differences in optical properties, thereby reducing the burden on the observer's brain.
3Measurement precision
If images with different brightness and stereo perspectives are combined, then depth of field and resolution are improved, but the observer's brain has to process images with different optical properties
Solution Approach 1:
The patent applies homogeneity by ensuring that both original images have the same brightness, depth of field, and optical properties. This is achieved through matched optical systems and consistent imaging conditions in both channels, which allows the observer's brain to process the stereoscopic pair without the additional burden of reconciling differences in optical properties, thereby reducing visual processing effort.

AI summary
A stereoscopic imaging device includes at least a first and a second image recording unit configured to record a first and a second original image of an object from different perspectives, wherein the original images differ at least with regard to one item of image information, an image display unit for imaging displayed images, an image processing unit for further processing the original images, and the image processing unit is configured to supplement at least one of the two original images with at least one item of image information from the other original image to generate a displayed image. In addition, a method for generating at least one displayed image that can be imaged on an image display unit is provided.
