3D Image Rotation Axis Shift for Distortion-Free Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image display methods distort 3D images when rotating them around an axis vertical to the display surface, failing to maintain the image's natural geometry and clarity.
Innovation Solution
The method involves displaying images in a three-dimensional fashion and rotating them around an imaginary axis vertical to the image surface but different from the display surface axis, using a display controller to adjust the image's orientation and spacing based on user instructions, ensuring clear and natural visual perception of the rotation.

Engineering Contradiction Analysis
1Ease of operation
If a 3D object image is rotated around an axis vertical to the display surface, then the rotation can be displayed, but the image becomes distorted and loses clarity
Solution Approach 1:
The patent changes the rotation axis from the display surface axis (Z-axis) to an imaginary axis that is vertical to the image surface itself. This dimensional change in the rotation reference allows the image to rotate without distortion by maintaining the image's local coordinate system integrity while achieving the desired rotation effect on the display surface.
Solution Approach 2:
The patent applies different rotation behaviors to different parts of the system: the display surface remains fixed with its own axis, while each image rotates around its own imaginary axis that is vertical to its surface. This local quality approach allows each image to maintain its geometric integrity while achieving rotation display.
2Illumination intensity
If multiple images are displayed in three-dimensional fashion, then visual perception is enhanced, but image overlap and confusion may occur
Solution Approach 1:
By rotating images around imaginary axes that are vertical to each image's surface rather than the display surface axis, the patent creates distinct rotation planes for each image. This dimensional differentiation allows multiple 3D images to coexist and rotate independently without overlapping or confusing each other, maintaining both visual enhancement and image clarity.

AI summary
An image display method includes: displaying a first image having a first image surface on a display surface in a three-dimensional fashion; in response to a reception of an instruction of rotating the first image around an axis different from any axis in the display surface, rotating the first image around a first imaginary axis, the first imaginary axis being vertical to the first image surface and different from an axis vertical to the display surface; and displaying the rotated first image.
