Solution Overview
Problem
Modern imaging devices with multi-layer image sensors face increased power consumption due to higher processing loads, necessitating the need for image processing techniques that can perform large amounts of processing without excessive power consumption.
Innovation Solution
An image processing device comprising a pixel array generating multiple color signals and a data processing unit that operates in parallel modes to generate output image data, either using all color signals for high-quality imaging or reducing data by converting signals into YUV format and processing two image signals to conserve power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multi-layer image sensors are used to generate multiple color signals, then image quality is improved, but power consumption increases
Solution Approach 1:
The image processing device dynamically switches between two operating modes: a first mode that processes all multiple color signals for high image quality, and a second mode that generates and processes only two image signals for power saving. This dynamic adaptation allows the system to optimize the balance between image quality and power consumption based on real-time requirements.
Solution Approach 2:
The system changes the processing parameter from handling multiple color signals (n signals) to handling a reduced set of two image signals. By transforming the multiple color signals into two image signals through a data processing unit, the system reduces processing load and power consumption while maintaining acceptable image quality through selective signal processing.
2Speed
If all color signals are processed in parallel, then processing speed is improved, but power consumption increases
Solution Approach 1:
Instead of processing all multiple color signals simultaneously, the system performs partial processing by selecting only two image signals for parallel processing in the second mode. This partial action approach maintains adequate processing speed for power-saving operations while significantly reducing the energy expenditure associated with processing all available color signals.
3Use of energy by moving object
If data processing is reduced to save power, then power consumption is reduced, but image quality may deteriorate
Solution Approach 1:
The system dynamically adapts its processing level based on requirements. When power saving is prioritized, it processes only two image signals; when image quality is prioritized, it processes all multiple color signals. This dynamic switching ensures that image quality is maintained at acceptable levels while enabling power-saving operations when appropriate.
Solution Approach 2:
The system changes the processing parameter between handling n color signals for high quality and handling 2 image signals for power saving. By controlling the transformation and selection of signals, the system maintains image quality within acceptable parameters while reducing processing load to conserve power when needed.
