Visual Perception Determination System for Legal Evidence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing prevalence of video recordings from various imaging devices in legal and judicial contexts often results in scenes that do not accurately reflect the visual perception of individuals involved, due to limitations in human visual field and adaptation to lighting conditions, which can impact the reliability of evidence.
Innovation Solution
A visual perception determination system that receives primary video or still images and corresponding vision impact parameters from sensors, identifying timing correlations to generate secondary images that reflect the observer's visual perception, including overlays and filters to adjust for focus and lighting adaptation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video recordings are captured using imaging devices, then the scene can be recorded for evidentiary purposes, but the recorded scene does not accurately reflect the observer's visual perception due to human visual limitations
Solution Approach 1:
The patent introduces an intermediary processing system that acts as a mediator between the raw video recording and the final evidentiary output. This system analyzes lighting conditions, pupil response data, and scene characteristics to generate corrected visual representations that more accurately reflect human visual perception, thereby resolving the discrepancy between mechanical recording and biological perception
Solution Approach 2:
The patent applies parameter changes by modifying video parameters (brightness, contrast, focus, field of view) based on measured physiological parameters such as pupil diameter, adaptation time, and focal length. These dynamic parameter adjustments transform the static mechanical recording into a dynamic representation that mimics human visual characteristics under varying conditions
2Measurement precision
If the eye pupil contracts or dilates to focus on objects at different distances, then the eye can focus on specific objects, but the field of view is limited and everything cannot be focused on at once
Solution Approach 1:
The patent segments the visual field into multiple depth planes and focus zones, analyzing pupil data to determine which segment the observer is currently focusing on. This segmentation allows the system to prioritize processing resources on the focused region while maintaining awareness of the broader scene, effectively managing the trade-off between focus precision and overall field of view
3Reliability
If the eye requires an adjustment period when transitioning between bright and dark environments, then the eye can adapt to new lighting conditions, but vision is impaired during the transition time
Solution Approach 1:
The patent implements preliminary action by detecting lighting condition changes in advance and proactively adjusting video parameters before the full adaptation period is complete. The system uses light sensors and historical adaptation data to predict the observer's visual state and pre-adjust brightness and exposure settings, reducing the effective adaptation time and maintaining vision accuracy throughout the transition

AI summary
Visual perception determination assistance system and method. In one embodiment, a method includes receiving, at an electronic computing device, a primary video or still image from an imaging device; receiving, at the electronic computing device, at least one vision impact parameter from at least one sensor device, the at least one vision impact parameter being indicative of an ability of an observer to visually perceive a scene captured in the primary video or still image; storing the primary video or still image and the at least one vision impact parameter in a memory; identifying, by a processor electrically coupled to the memory, a timing correlation between the primary video or still image and the at least one vision impact parameter; and storing the timing correlation in the memory.
