VR Display Resolution Compression via Grayscale Segmentation

Solution Overview

Problem

The increasing contradiction between data volume and bandwidth in virtual reality devices leads to undesirable experiences such as delays and lags when displaying high-definition content, due to excessive data requirements.

Innovation Solution

A display method that segments an image frame into regions, determines grayscale information for each region, and applies a resolution compression ratio based on this information, reducing data transmission by outputting display data efficiently across pixel units.

1Measurement precision

If high-definition resources are used to improve display quality, then image resolution is improved, but data volume increases causing delays and lags

Engineering Contradiction:

Improveimage resolutionVSAvoiddisplay delay

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The display screen is divided into multiple grayscale regions, with each region assigned a different resolution compression ratio based on its grayscale characteristics. This segmentation allows different parts of the image to be processed at different resolutions, reducing overall data transmission requirements while maintaining visual quality in critical areas.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different resolution compression ratios are applied to different grayscale regions of the display screen. Regions with lower grayscale values (darker areas) use higher compression ratios, while regions with higher grayscale values (brighter areas) use lower compression ratios. This local differentiation optimizes bandwidth utilization by allocating more data resources to visually critical regions.

Inventive Principle:

Principle #3Local quality
