Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Three-dimensional still images are difficult for viewers to perceive depth without aids like polarized glasses, and large parallax in three-dimensional images displayed on a monitor reduces the area enabling depth perception, causing discomfort to the viewer.
Innovation Solution
A three-dimensional image display device and method that dynamically changes the pop-out amount of three-dimensional images over time, using a timer unit, pop-out amount change mode memory, pop-out amount controller, changing image producer, and display controller to enhance depth perception and entertainment quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a planar image is displayed full-screen on a monitor with great parallax between multiple images, then depth perception is enhanced, but the area enabling depth perception decreases and viewer discomfort increases
Solution Approach 1:
The patent applies the dynamics principle by dynamically changing the pop-out amount of the three-dimensional image over time. The pop-out amount controller adjusts the displacement between left and right eye images based on time-dependent change information, transforming a static display into a dynamic one that adapts to viewer perception needs, thereby resolving the contradiction between enhancing depth perception and maintaining adequate display area.
Solution Approach 2:
The patent utilizes parameter changes by modifying the pop-out amount parameter over time. The pop-out amount change mode memory stores time-dependent change information that adjusts the parallax parameter dynamically, allowing the system to optimize depth perception effectiveness while preventing viewer discomfort from excessive or static parallax.
2Ease of manufacture
If still images are used for three-dimensional display, then depth perception is difficult to achieve without aids like polarized glasses, but using aids increases device complexity
Solution Approach 1:
The patent extracts the need for external viewing aids by implementing a software-based solution that generates pop-out amount changing images through image processing. Instead of requiring polarized glasses or other physical aids, the system processes the images to create dynamic pop-out effects that enhance depth perception using only the display device and software controller.
Solution Approach 2:
The patent replaces the mechanical/optical system of polarized glasses and specialized display hardware with an electronic image processing system. The pop-out amount controller and changing image producer use computational methods to create depth perception effects, substituting physical viewing aids with software-based image manipulation.

AI summary
A three-dimensional (3D) image display device enables easy recognition of a 3D image by appropriately changing the popout amount of a 3D image. The display device includes a timer setting and measuring a given time over which the popout amount of a 3D image changes, a popout amount change mode memory storing information on time dependent change of the popout amount occurring over the given time, a popout amount controller producing the popout amount for each unit time based on parallax between a plurality of images, the given time, and the time dependent change information, a changing image producer producing pairs of popout-amount-changing images from the plurality of images according to a popout amount by the unit time, a 3D image producer producing a corresponding popout-amount-changing 3D image, and a display controller.
