Image Generation Device Parallax Adjustment for Viewer Fatigue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image generation technologies fail to effectively reduce viewer fatigue even when parallax is adjusted within the depth of focus, leading to continued fatigue during video viewing.
Innovation Solution
An image generation device that acquires fatigue data and calculates parallax adjustment values to minimize parallax changes over time, adjusting the image's stereoscopic effect based on viewer fatigue levels, using a combination of hardware and software components including a processor, detection device, and recording unit to associate and apply fatigue and parallax data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If parallax is adjusted within the depth of focus range, then the video system should reduce viewer fatigue, but the viewer still experiences fatigue due to insufficient dynamic adaptation
Solution Approach 1:
The system continuously monitors viewer fatigue levels and uses this feedback to dynamically adjust parallax settings. The fatigue detection unit measures physiological indicators (such as eye movement, pupil diameter, or facial muscle tension) and feeds this information back to the parallax adjustment unit, which modifies the stereoscopic effect in real-time to maintain optimal viewing comfort.
Solution Approach 2:
The system transitions from static parallax adjustment to dynamic adaptation by continuously changing parallax levels based on real-time fatigue detection. The parallax adjustment unit modifies stereoscopic parameters dynamically throughout the viewing session, adapting to the viewer's changing physiological state rather than maintaining fixed settings.
2Object-affected harmful factors
If parallax adjustment value is increased to enhance stereoscopic effect, then the stereoscopic effect is improved, but the amount of change in parallax per unit time exceeds acceptable limits causing discomfort
Solution Approach 1:
The system changes parallax parameters dynamically based on fatigue levels. When fatigue is detected, the parallax adjustment unit modifies stereoscopic parameters (such as interocular distance or convergence angle) within acceptable change rates, balancing effect enhancement with comfort by controlling the rate of parameter transitions.
Solution Approach 2:
The system takes preliminary action by detecting fatigue before it leads to significant discomfort and adjusts parallax proactively. The fatigue detection unit identifies early signs of fatigue, and the parallax adjustment unit preemptively modifies stereoscopic parameters to prevent further fatigue accumulation, rather than waiting for complaints or extreme discomfort.

AI summary
The present invention is to adjust a stereoscopic effect of at least one of a moving image and a still image to make it difficult to fatigue a viewer. An image generation device includes a fatigue data acquisition unit that acquires fatigue data indicating information on fatigue of a viewer, a parallax adjustment value data acquisition unit that calculates parallax adjustment value data including a parallax adjustment value on the basis of the fatigue data, and a parallax adjustment unit that adjusts a parallax of an image on the basis of the parallax adjustment value,
