Innovation Solution
An anaglyphic image presentation system that uses an anaglyphic image display device and transmission filter lenses to simulate depth perception by matching peak wavelengths emitted by colored indicia with those transmitted through the lenses, reducing color bleed-through and enhancing image clarity, allowing users to perceive objects at varying depths through precise control of pixdelta.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional anaglyphic systems are used for depth perception training, then depth perception can be trained, but the optics are poor and image filtering capabilities are limited
Solution Approach 1:
The patent applies parameter changes by precisely controlling the wavelength parameters of the light sources to match the transmission characteristics of the dichroic filters. The system adjusts the peak wavelengths of red and blue light sources to align with the peak transmission wavelengths of their corresponding filters, optimizing the anaglyphic effect and eliminating color bleed-through, thereby achieving high image clarity while maintaining effective depth perception training
Solution Approach 2:
The patent employs composite optical filtering using dichroic filters that combine multiple transmission characteristics in a single optical element. These filters are designed to transmit specific wavelength ranges (red or blue) while blocking other wavelengths, creating a composite filtering effect that provides superior image separation and clarity compared to traditional single-layer filters
2Measurement precision
If LCD eyewear with synchronized display is used, then image clarity can be improved, but the system becomes expensive and cumbersome
Solution Approach 1:
The patent replaces expensive, complex LCD eyewear with a simpler, more affordable optical system using dichroic filters and colored light sources. This approach uses inexpensive optical components that can be easily manufactured and distributed, eliminating the need for expensive liquid crystal technology while maintaining effective depth perception training capabilities
Solution Approach 2:
The patent extracts and isolates the essential function of wavelength-based image separation from complex LCD technology, using only the core optical filtering principle. By removing unnecessary complexity and focusing on the fundamental optical effect, the system achieves image clarity through simple dichroic filters and colored illumination without requiring synchronized display technology

AI summary
An anaglyphic image presentation system is provided to evaluate and train a user's depth perception abilities. In embodiments, anaglyphic image target components are presented to a user on a display device. The image target components are then viewed by the user through a set of transmission filter lenses. The transmission filter lenses present and block one or more target components based on the peak wavelength transmission associated with each lens. As a result, a user perceives an anaglyphic target image that is resultant from the perceived image target components when viewed through the transmission filter lenses.
