Perforated Image Screen Structure for View-Dependent Animation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image rendering techniques using picture perforation lack the ability to create a perception of movement or animation without the use of film cinematography, and there is a need for innovative methods to achieve image isolation and movement illusions.
Innovation Solution
A structure comprising a lower perforated screen with alternating image lines and an upper defining screen, where the upper screen is spaced to allow selective viewing of different images based on the observer's perspective, creating an animated effect by alternating patterns of perforations and apertures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single perforated screen with multiple images is used, then multiple images can be displayed, but image isolation and selective viewing cannot be achieved
Solution Approach 1:
The display system is segmented into two separate screens: a lower perforated screen containing multiple images and an upper defining screen with apertures. This segmentation allows each screen to perform a specific function - the lower screen provides multiple images while the upper screen enables selective viewing through aperture positioning, thereby achieving both multiple image display and image isolation simultaneously.
Solution Approach 2:
The invention adds a vertical dimension by stacking two screens at different heights and spacing them apart. The upper defining screen is positioned above the lower perforated screen at a specific distance, creating a three-dimensional arrangement. This dimensional addition enables the aperture to selectively view different image lines from the lower screen based on the viewer's horizontal position, achieving image isolation while maintaining multiple image capability.
2Length of stationary object
If the upper defining screen is placed close to the lower perforated screen, then structural compactness is improved, but selective viewing and image isolation are compromised
Solution Approach 1:
The invention optimizes the spacing parameter between the upper and lower screens to a specific range (20-50mm, preferably 30mm). This parameter change is critical: if the screens are too close, the aperture cannot effectively isolate different image lines; if too far, the structural compactness is compromised. The optimized spacing enables the aperture to selectively view different image lines while maintaining a compact overall structure.
3Measurement precision
If traditional picture perforation methods are used, then image rendering is achieved, but perception of movement or animation cannot be created
Solution Approach 1:
The invention introduces dynamic interaction between the viewer and the display system. As the viewer moves horizontally, different apertures align with different image lines on the lower screen, causing the perceived image to change dynamically. This dynamic viewing experience creates the perception of movement or animation while maintaining precise image rendering through the fixed perforation and aperture patterns.
Solution Approach 2:
The alternating pattern of image lines on the lower screen, combined with the periodic movement of the viewer, creates a periodic visual effect. As the viewer moves back and forth or changes position, they periodically encounter different aperture-image line alignments, resulting in a sequence of different images that creates an animated effect through repeated cycles of image transitions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The structure provides a perception of animated images by allowing different images to be viewed from specific locations, achieving a cyclic animated effect as the observer moves, enhancing the illusion of movement without the need for film cinematography.
Implementation Method 1
the first perforations in each first image line allowing passage of an amount of light that represents an individual pixel or group of pixels of the first image
Implementation Method 2
Some of the light passing through the lower perforated screen will be blocked by the upper defining screen and will not reach the observer's eye
Implementation Method 3
as the observer moves relative to the structure different perforations (in the lower screen) will align with the apertures (in the upper screen) creating a continuously different visual effect for the observer

AI summary
A structure for depicting a plurality of images has a lower perforated screen having the plurality of images. A first image is formed from first perforations arranged in a series of first image lines. A second image is formed from second perforations arranged in a series of second image lines. An upper defining screen is arranged substantially co-planarly over the lower perforated screen. A width of defining apertures in the upper defining screen is about the width of the first image lines and the second image lines so that from any viewing perspective the first image or the second image can be isolated for viewing. The first image is viewable from a first viewing location and the second image is viewable from a second viewing location so that repeated movement of an observer between the first and second viewing locations allows the plurality of images to appear to be animated.
