Image Generation Device Luminance Variation Motion Illusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques fail to create a moving illusion for stationary objects when the luminance of the object and varying areas cannot be matched, preventing the perception of motion.
Innovation Solution
An image generation device generates video with a stationary object area, at least one luminance varying area along its contour, and a background area, where the luminance of the varying area varies within a range based on the object and background luminance, ensuring the object appears to move even without established apparent motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the luminance of the stationary object area and the luminance of the luminance varying area are matched to establish apparent motion, then a feeling that the stationary object is moving is given, but it becomes impossible to implement when luminance matching cannot be achieved
Solution Approach 1:
The patent changes the luminance parameters of the varying areas dynamically over time, creating a temporal pattern where luminance increases and decreases in a specific sequence. This temporal parameter change allows the motion illusion to occur without requiring spatial luminance matching between objects, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The patent applies periodic luminance variation to the areas surrounding the stationary object, creating rhythmic patterns of light and dark that induce apparent motion. This periodic action replaces the need for static luminance matching with dynamic temporal patterns, enabling the technique to work across different luminance conditions.
2Reliability
If the luminance of the luminance varying area is varied with time in a luminance range that includes both the stationary object area luminance and the background area luminance, then apparent motion is established, but the technique cannot be implemented when luminance matching is not possible
Solution Approach 1:
The patent modifies the luminance parameters of the varying areas over time, creating a temporal progression that establishes apparent motion without requiring the varying areas to match the stationary object's luminance. This approach makes implementation feasible in situations where luminance matching would otherwise be impossible.
Solution Approach 2:
The patent introduces the background area luminance as an intermediary reference point. The luminance varying area transitions through the background luminance level, creating a mediator effect that establishes apparent motion without direct matching between the stationary object and varying areas, thereby improving implementation feasibility.
3Reliability
If the luminance of the first luminance varying area and the luminance of the stationary object area become equal, then a feeling that the stationary object is moving in the direction of the first luminance varying area is given, but this requires precise luminance matching that may not be achievable
Solution Approach 1:
The patent employs temporal parameter changes in luminance to create motion direction perception without requiring precise spatial luminance matching. By varying luminance over time in a controlled pattern, the system achieves reliable motion direction perception while reducing the need for high manufacturing precision in luminance matching.

AI summary
A feeling is given that a stationary object is moving even when an apparent motion is not established between the stationary object and luminance varying areas. An image generation device generates video including a stationary object area, at least one luminance varying area located along a contour of the stationary object area, and a background area other than the stationary object area and the luminance varying area. Luminance of the luminance varying area varies with time in a luminance range based on luminance of the stationary object area and luminance of the background area. (1) Luminance of the stationary object area is brighter than luminance of the background area, and a maximum value of luminance of the luminance varying area is smaller than or equal to luminance of the background area, or (2) luminance of the stationary object area is darker than luminance of the background area, and a minimum value of luminance of the luminance varying area is larger than or equal to luminance of the background area.
