Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multiple channel imaging systems face challenges in reducing overall power consumption, particularly in managing energy usage across different spectral bandwidths.
Innovation Solution
A method and system where a first imaging sensor monitors a field of view and activates a second imaging sensor from a standby state to an active state upon detecting changes, such as contrast or movement, allowing for the creation of composite images while deactivating sensors during inactivity to conserve power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple imaging sensors operate continuously in all spectral bands, then complete imaging coverage and information fusion are achieved, but power consumption increases significantly
Solution Approach 1:
The patent implements dynamic power management by transitioning imaging sensors between active and standby states based on detected scene changes. The controller monitors the field of view and selectively activates sensors only when changes are detected, making the system's operational state dynamic rather than static. This resolves the contradiction by adapting power consumption to actual imaging needs while maintaining complete imaging coverage when required.
Solution Approach 2:
The system employs periodic monitoring of the field of view by a first imaging sensor to detect changes, then periodically activates second imaging sensors only when changes are detected. This periodic activation pattern rather than continuous operation reduces power consumption while ensuring that complete multi-spectral imaging coverage is achieved when scene changes occur.
2Measurement precision
If imaging sensors operate at full power continuously, then image quality and detection sensitivity are maintained, but thermal management requirements increase
Solution Approach 1:
The patent dynamically adjusts sensor operational states based on scene activity. When no changes are detected in the field of view, sensors transition to standby states with reduced power consumption and lower thermal output. When scene changes are detected, sensors activate to full power to maintain detection sensitivity. This dynamic approach resolves the contradiction by matching thermal output to actual detection needs.
3Adaptability or versatility
If all imaging sensors are activated simultaneously, then complete spectral coverage is achieved, but system complexity and power requirements increase
Solution Approach 1:
The patent segments the multi-spectral imaging system into multiple independent imaging sensors, each capable of operating in different spectral bands. The controller selectively activates specific sensors based on detected scene changes, rather than activating all sensors simultaneously. This segmentation allows the system to achieve complete spectral coverage when needed while reducing operational complexity by activating only the necessary subset of sensors.
Solution Approach 2:
The first imaging sensor serves multiple functions: it acts as both a primary imaging device and a change-detection sensor that triggers activation of second imaging sensors. This multi-functionality reduces the need for separate control mechanisms and simplifies the overall system architecture while maintaining adaptability across multiple spectral bands.

AI summary
A method of imaging includes monitoring a field of view with a first imaging sensor of a multiple channel imaging system and activating a second component of the imaging system from a stand by state to an active state upon detection of a change in the field of view of the first imaging sensor. The second component can include a second imaging sensor. The second imaging sensor can have a field of view overlapping with the field of view of the first imaging sensor. The first imaging sensor can be configured for imaging in a first spectral range, wherein the second imaging sensor is configured for imaging in a second spectral range that is different from the first spectral range. The first and second spectral ranges can be overlapping or non-overlapping.
