Adaptive Image Compression for Mobile Power and Traffic Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices face challenges in efficiently managing image data display due to high power consumption, particularly in managing refresh rates and compression methods, which affect both data traffic and image quality.
Innovation Solution
Adaptive adjustment of refresh rates and compression methods based on image motion, using a compression rate determining unit to classify image data into motion levels and apply corresponding refresh and compression rates, such as reducing refresh rates and increasing compression for high-motion images, while maintaining image quality and data efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high refresh rate and low compression rate are used, then image quality is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the refresh rate and compression rate adjustable rather than fixed. The system dynamically changes these parameters based on motion detection in image data, allowing optimization between image quality and power consumption depending on the specific display scenario
Solution Approach 2:
The patent changes physical parameters (refresh rate and compression rate) based on motion information. When motion is detected, the system adjusts these parameters to balance image quality and power consumption, directly applying parameter changes to resolve the contradiction
2Quantity of substance
If high compression rate is applied, then data traffic is reduced, but image quality deteriorates
Solution Approach 1:
The patent applies local quality by differentiating compression treatment based on motion regions. The system identifies motion information in image data and applies appropriate compression rates to different regions or frames, maintaining quality where needed while reducing data traffic in appropriate areas
Solution Approach 2:
The system changes the compression rate parameter dynamically based on motion detection. By adjusting this parameter according to motion information, the patent optimizes the balance between data traffic reduction and image quality preservation
3Stability of the object's composition
If fixed refresh rate is used, then display consistency is maintained, but power efficiency decreases
Solution Approach 1:
The patent transforms the fixed refresh rate into a dynamic parameter that adapts to motion content. The system maintains display consistency through controlled adjustments while improving power efficiency by reducing refresh rates during static or low-motion periods
