Dynamic Image Compression for Display Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display technologies consume excessive power due to large data sizes when display data is not compressed, as they often compress data minimally or not at all, leading to increased power consumption during image display.
Innovation Solution
A method and device that obtain display definition information, determine a target image compression ratio based on prestored correspondence, and compress display data accordingly, allowing for higher compression levels when high image quality is not needed, thereby reducing data size and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If display data is not compressed or compressed at minimum level, then image quality is maintained, but data size is large and power consumption is high
Solution Approach 1:
The patent applies dynamics by making the compression ratio adjustable rather than fixed. The graphics processor dynamically selects different compression ratios based on real-time conditions such as cache memory availability, display definition requirements, and power consumption needs. This allows the system to adapt between minimal compression (when quality is priority) and high compression (when power saving is priority), resolving the contradiction between power consumption and data size.
Solution Approach 2:
The patent changes the compression parameter from a fixed minimum level to a variable parameter that can be adjusted according to different display scenarios. By establishing a correspondence between display definition information and appropriate compression ratios, the system can select optimal compression levels that balance power consumption against data size, directly addressing the technical contradiction.
2Use of energy by moving object
If display data is compressed at higher levels, then data size is reduced and power consumption is lowered, but image quality may be compromised
Solution Approach 1:
The patent resolves this contradiction by introducing display definition information as a key parameter in the compression decision process. The system maintains image quality by selecting appropriate compression ratios that match the required display definition level. For high-definition displays, lower compression ratios preserve image quality, while for lower-definition displays, higher compression ratios are acceptable, thus balancing power consumption with image quality requirements.
Solution Approach 2:
The system dynamically adjusts compression intensity based on the specific display scenario. When high image quality is required (e.g., for detailed graphics or high-resolution displays), the system selects lower compression ratios. When power saving is more critical and image quality requirements are lower, the system applies higher compression ratios, thus dynamically resolving the quality-power consumption trade-off.
3Manufacturing precision
If display data size is large, then image quality is preserved, but transmission time and processing time increase
Solution Approach 1:
The patent addresses this contradiction by changing the compression parameter based on display definition information. The system determines an appropriate compression ratio that maintains sufficient image quality for the specific display device while minimizing data size. This parameter adjustment reduces transmission time without compromising the quality required for the target display, thus resolving the contradiction between image quality and transmission time.
