Viewpoint-Adaptive Display Control with Generated Image Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with image separators like parallax barriers struggle to adapt flexibly to varying user viewpoint arrangements, leading to inaccuracies in image display due to fixed viewpoint arrangements that do not align with the user's position.
Innovation Solution
A display device with a display panel, light source, and image processing components that dynamically adjust image display based on user viewpoint information, using a controller to select and generate image data that aligns with the user's position and orientation, even when pre-stored data is unavailable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed arrangement direction of viewpoints is used with an image separator, then the device structure is simple, but the adaptability to varying user positions deteriorates
Solution Approach 1:
The patent applies dynamics by making the viewpoint arrangement direction changeable rather than fixed. The controller dynamically adjusts the arrangement direction of multiple viewpoints according to the detected user position, allowing the display device to adapt to different viewing scenarios while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent changes the parameter of viewpoint arrangement direction based on user position detection. By detecting the user's position and accordingly adjusting the arrangement direction parameter of the viewpoints, the system achieves adaptability without requiring complex mechanical structures.
2Device complexity
If pre-prepared image data is used for fixed viewpoints, then the image display is simple, but the accuracy of image adaptation to user positions deteriorates
Solution Approach 1:
The patent implements feedback by detecting the user's actual position and using this information to adjust the viewpoint arrangement direction and select appropriate image data. This closed-loop feedback mechanism ensures that the displayed images accurately correspond to the user's position, improving adaptation accuracy.
Solution Approach 2:
The patent prepares multiple sets of image data in advance, each corresponding to different viewpoint arrangements. When the user position is detected, the system selects the pre-prepared image data that best matches the current situation, combining preliminary preparation with real-time selection to achieve both simplicity and accuracy.
3Device complexity
If the arrangement direction of viewpoints is fixed, then the device design is straightforward, but the flexibility to accommodate different display scenarios deteriorates
Solution Approach 1:
The patent makes the viewpoint arrangement dynamic by allowing it to change according to detected user positions. This dynamic adjustment capability provides flexibility for different display scenarios while maintaining straightforward device design, as the changes are achieved through software control rather than mechanical reconfiguration.
Data Source
AI summary
A display device includes: a display panel with pixels; a light source with light emission points; an acquirer configured to acquire information on viewpoints of a user; a storage configured to store image data; and a controller configured to control image display based on the information. The controller selects one piece of image data and display the one piece of the image data by controlling some of the pixels to transmit light, which are located on straight lines connecting the light emission points and the viewpoints. When first image data corresponding to a first positional relation between the display panel and the viewpoints is not stored in the storage, the controller causes the image generator to generate, based on two pieces of image data corresponding to second positional relations close to the first positional relation, second image data corresponding to the first positional relation and selects the second image data.
