3D Image Output Device Parallax Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying three-dimensional images with parallax correction often result in errors and unnatural images, leading to an unsuitable stereoscopic effect when display conditions change.
Innovation Solution
A three-dimensional image output apparatus and method that selects and reselects image data based on current display and viewing conditions, adjusting image data to maintain optimal parallax within a target range, ensuring a suitable stereoscopic effect by dynamically changing the image data used for display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If signal processing is used to correct parallax and generate new images, then parallax can be adjusted according to screen size, but errors and occlusions occur causing unnatural images and unsuitable stereoscopic effect
Solution Approach 1:
Multiple images are captured in advance at different positions before display. By pre-capturing images at various viewpoints, the system has a library of valid images to select from, avoiding the need to generate images through problematic signal processing when display conditions change.
Solution Approach 2:
Instead of generating new images through signal processing, the system selects and displays actual captured images from the pre-captured set. This copying approach uses real image data rather than processed synthetic images, eliminating errors and occlusions.
2Area of stationary object
If screen size increases to provide larger display, then more users can view the image, but parallax increases proportionally making stereoscopic viewing difficult
Solution Approach 1:
The system dynamically selects different image pairs from the pre-captured images based on the actual screen size and viewing conditions. When screen size changes, the system adapts by choosing appropriate images with suitable parallax, rather than using a fixed image pair.
Solution Approach 2:
The system changes the selection parameters based on screen size - selecting image pairs with smaller parallax for larger screens and larger parallax for smaller screens. This parameter adaptation maintains suitable stereoscopic effect across different display sizes.
3Adaptability or versatility
If image data is reselected based on display magnification changes, then suitable stereoscopic effect is maintained, but additional processing is required
Solution Approach 1:
Images are pre-captured at multiple positions and stored with metadata about their viewpoint and parallax characteristics. This preliminary organization allows the system to quickly select appropriate images based on display magnification without complex real-time processing.

AI summary
A three-dimensional image output apparatus according to a present invention includes a storage that stores image data of a plurality of images obtained by shooting the same one scene at different positions, a selector that selects two image data as image data for stereoscopic viewing from a plurality of image data stored in the storage, and an obtainer that obtains at least one of a display condition at a time of displaying a three-dimensional image relating to the image data stored in the storage and a viewing condition at a time of viewing the three-dimensional image. When at least one condition obtained by the obtainer is different from a currently set condition, the selector reselects two image data from the plurality of image data to outputting the reselected image data.
