Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Virtual Reality (VR) technology, the high resolution and refresh rate requirements lead to increased data transmission amounts, which can result in reduced refresh rates and increased power consumption.
Innovation Solution
The method involves performing different rendering algorithms on different display regions at the display device, achieving fixation point rendering effects, reducing data transmission, saving power, and increasing refresh rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high resolution rendering is applied to the entire display screen, then the image quality is improved, but the data transmission amount increases and refresh rate decreases
Solution Approach 1:
The patent applies different rendering qualities to different regions of the display screen. The fixation point region (where the user is looking) is rendered at high resolution, while the peripheral regions are rendered at lower resolution. This local quality differentiation maintains image quality in the important area while reducing overall data transmission requirements, thereby preserving high refresh rates.
Solution Approach 2:
The display screen is segmented into multiple regions: a fixation point region and peripheral regions. Each region is processed with appropriate rendering algorithms - high-resolution rendering for the fixation point and lower-resolution rendering for peripheral areas. This segmentation allows the system to optimize between quality and performance by treating different areas differently.
2Measurement precision
If high resolution rendering is applied to the entire display screen, then the image quality is improved, but the power consumption increases
Solution Approach 1:
The patent implements local quality rendering where only the fixation point region receives high-resolution processing, while peripheral regions use lower-resolution rendering. This significantly reduces the computational power required for image processing, thereby reducing power consumption while maintaining acceptable image quality in the critical viewing area.
Solution Approach 2:
Instead of applying full high-resolution rendering to the entire screen (excessive action), the patent applies high-resolution rendering only to the necessary fixation point region (partial action). This partial rendering approach reduces computational load and power consumption while still delivering high quality where the user actually looks.
3Speed
If traditional rendering algorithms are used on all display regions, then the rendering speed is maintained, but the data transmission amount increases
Solution Approach 1:
The patent applies different rendering algorithms to different regions: fast rendering algorithms are used for peripheral regions where high detail is not critical, while more detailed rendering is applied only to the fixation point region. This local differentiation reduces the total data transmission amount while maintaining rendering speed through optimized algorithm selection for each region.

AI summary
An image display method, a display system, and a computer-readable storage medium are disclosed. The image display method includes: acquiring a first image; determining a first region and a second region in the first image; performing a first rendering algorithm on the first region in the first image and performing a second rendering algorithm on the second region in the first image, so as to obtain a second image, where a rendering resolution of the first rendering algorithm is greater than a rendering resolution of the second rendering algorithm; and displaying the second image.
