Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wearable computing technologies face challenges in efficiently capturing and processing eye reflection images to generate accurate point-of-view images for life-log recording, particularly in real-time applications such as augmented or virtual reality, due to artifacts from eye features and limited image quality.
Innovation Solution
A method involving inward-facing cameras to capture electromagnetic radiation reflected from the eye, filtering techniques to remove eye-related artifacts, and super-resolution methods to enhance image quality, allowing for the generation and storage of point-of-view images, which can be used to create life-log entries with associated data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If eye reflection images are captured using inward-facing cameras, then point-of-view images can be generated for life-log recording, but artifacts from eye features degrade image quality
Solution Approach 1:
The patent extracts and removes eye-related artifacts from the captured reflection images through filtering techniques. The system identifies and separates unwanted eye feature artifacts from the useful point-of-view information, eliminating the harmful components while preserving the desired image content.
Solution Approach 2:
The patent converts the harmful eye reflection artifacts into beneficial information by analyzing the reflection patterns to determine eye orientation and gaze direction. The same reflected light that causes artifacts also provides valuable data about the user's viewing direction, which is then used to correct and enhance the point-of-view image.
2Measurement precision
If filtering techniques are applied to remove eye-related artifacts, then image quality improves, but processing complexity increases
Solution Approach 1:
The patent segments the image processing into distinct stages: initial capture of reflection images, identification of eye feature artifacts, application of filtering techniques, and final reconstruction of point-of-view images. This segmentation allows each processing stage to be optimized independently, managing complexity while maintaining accuracy.
Solution Approach 2:
The patent introduces intermediate processing steps that act as mediators between the raw captured images and the final point-of-view images. Filtering algorithms and artifact removal techniques serve as intermediaries that systematically reduce complexity by breaking down the complex task of artifact removal into manageable computational steps.
3Manufacturing precision
If super-resolution methods are used to enhance image quality, then point-of-view image detail improves, but computational requirements increase
Solution Approach 1:
The patent applies preliminary filtering and artifact removal before super-resolution enhancement. By preprocessing the images to remove eye-related artifacts and optimize the input quality, the subsequent super-resolution processing requires less computational power to achieve the same level of detail enhancement.
Solution Approach 2:
The patent adjusts processing parameters dynamically based on the specific characteristics of each captured image. By optimizing super-resolution parameters according to the quality and content of the input reflection images, the system achieves high detail quality while minimizing unnecessary computational expenditure.
