Lenticular Image Formation for Variable Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing variable image display methods using lenticular sheets struggle to accurately reproduce the motion and size consistency of moving subjects, such as trains or cars, leading to incongruity in the displayed images.
Innovation Solution
A method involving a lenticular sheet with cylindrical lenses, where captured images of a moving subject are scaled and positioned to maintain consistent subject size, then superimposed and trimmed to create display image strips that are arranged to form lenticular images, ensuring the subject appears at a consistent size across different images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If captured images are used directly without scaling adjustment, then the original image details are preserved, but the subject appears in different sizes causing incongruity in the variable image display
Solution Approach 1:
The patent applies parameter changes by scaling the captured images to adjust the subject size to a predetermined standard size. This involves changing the dimensional parameters of the images while preserving the essential visual information, thereby achieving size consistency without completely losing the original image characteristics
Solution Approach 2:
The patent performs preliminary scaling and positioning adjustments on the captured images before assembling them into lenticular images. By pre-adjusting the subject size and position in the captured images, the system ensures that when the images are viewed through the lenticular sheet, the subject appears consistent in size across different viewing angles, preventing incongruity
2Reliability
If the background is fixed using a single image, then the background remains stable, but the image lacks realism and the subject motion details are difficult to reproduce
Solution Approach 1:
The patent segments the image into subject and background components. The background is extracted and fixed as a stable reference, while the subject is separately processed through scaling and positioning adjustments. This segmentation allows the background to remain stable while the subject can be precisely adjusted to maintain realism and detail
Solution Approach 2:
The patent uses the fixed background as an intermediary reference frame. By establishing a stable background layer, the system creates a reference against which the scaled and positioned subject images can be consistently aligned, thereby maintaining both background stability and subject motion detail reproduction
3Adaptability or versatility
If multiple images are synthesized to show subject motion, then the motion can be expressed, but the subject size varies noticeably causing incongruity
Solution Approach 1:
The patent applies parameter changes by systematically scaling each captured image so that the subject appears at a predetermined standard size. This parameter adjustment is applied uniformly across all images in the sequence, allowing motion to be expressed through position changes while maintaining consistent subject size, thereby eliminating noticeable size variations and incongruity

AI summary
A variable image display body and a lenticular image formation method that are capable of displaying a variable image without incongruity are provided. In a variable image display body 100 including a lenticular sheet 10 having a plurality of cylindrical lenses arranged in a first direction and lenticular images 20 arranged on a surface on the opposite side to the surface of the cylindrical lenses, the lenticular images 20 are composed of arranged image strips obtained by scaling a plurality of images so that subject images appearing in the respective images have the same size, subjecting the scaled images to position adjustment so that reference portions of the subject images in the scaled images are located at the same position and superimposing the scaled images, and in the superimposed state, trimming a region in which a predetermined number of the scaled images are overlapped and the subject images are included, and extracting image strips in the form of lines from each of the trimmed images.
