Head-Mounted Display Image Region Division for Processing Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices that show images for the left and right eyes require processing to increase the resolution of input images, leading to a high processing load and increased load on the system, which can result in inefficiencies and discomfort for the user.
Innovation Solution
A display device with two units for left and right eye images, where the images are divided into regions and pseudo-image regions are added to reduce processing load and improve transfer speed, allowing users to visually recognize the target image effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image resolution is increased to display high-vision images on two liquid crystal panels, then image quality is improved, but processing load increases
Solution Approach 1:
The display area is segmented into multiple regions (first display area, second display area, third display area) that are arranged in a specific configuration. By dividing the display into separate regions with different resolutions or processing requirements, the system can reduce the overall processing load while maintaining high-vision quality in critical areas. The segmentation allows different parts of the image to be processed at different resolutions, avoiding the need to process the entire image at maximum resolution.
2Adaptability or versatility
If two screens are combined to display images for left and right eyes, then stereoscopic display capability is improved, but processing load increases
Solution Approach 1:
The patent combines multiple display areas (first, second, and third display areas) into a unified stereoscopic display system. The first and second display areas are configured to display images for the left and right eyes respectively, while the third display area provides additional functionality. By merging these areas in a specific configuration, the system achieves stereoscopic display capability while optimizing the processing load through shared processing resources and coordinated control.

AI summary
A head-mounted display device includes a left optical-image display unit that displays an image corresponding to the left eye of a user and a right optical-image display unit that displays an image corresponding to the right eye of the user. An image processing unit divides a display target image and outputs an image for left eye and an image for right eye including divided images to the left optical-image display unit and the right optical-image display unit. The image for left eye and the image for right eye include image regions configured by the images divided by the image processing unit and non-image regions not including the divided images. A state of the non-image region of one of the image for left eye and the image for right eye corresponds to a state of the image region of the other.
