Imaging Mode Control with Feature Verification for Low Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surveillance cameras consume excessive power due to unnecessary shifts to high-resolution imaging mode caused by erroneous motion detection, limiting power consumption reduction.
Innovation Solution
An imaging apparatus with a mode control unit that shifts between motion detection, feature detection, and imaging modes based on detected motion and specific features, using lower resolution modes to minimize unnecessary high-resolution imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the mode is shifted to normal mode when motion is detected on pixel-binning mode, then high-resolution images can be captured, but power consumption increases due to unnecessary shifts caused by erroneous detection
Solution Approach 1:
The patent introduces a verification process as an intermediary step between motion detection and mode switching. When motion is detected in pixel-binning mode, the system first verifies the motion validity by checking multiple consecutive frames or using additional detection criteria before switching to normal mode, thereby filtering out erroneous detections while maintaining responsive imaging for genuine events
Solution Approach 2:
The system performs preliminary verification of detected motion by analyzing additional parameters or consecutive frames before committing to a mode switch. This preliminary action prevents premature transitions to high-resolution mode caused by false motion signals, reducing unnecessary power consumption while preserving the ability to respond to genuine motion events
2Manufacturing precision
If surveillance cameras constantly capture images at high-resolution, then image quality is maintained, but power consumption increases
Solution Approach 1:
The patent implements dynamic mode switching between pixel-binning mode (low resolution, low power) and normal mode (high resolution, high power) based on real-time motion detection results. The system adapts its imaging resolution to the actual surveillance needs, maintaining high image quality only when motion is detected while consuming minimal power during static conditions
Solution Approach 2:
The system changes the imaging resolution parameter dynamically based on detection results. By switching between two distinct resolution states (low in pixel-binning mode, high in normal mode) according to motion presence, the system optimizes the balance between image quality and power consumption

AI summary
Provided is an imaging apparatus including a mode control unit. The mode control unit shifts, when a motion is detected on a motion detection mode to detect the motion on the basis of image information, the mode to a feature detection mode to detect features on the basis of image information having a higher resolution than a resolution of the image information that is used for the motion detection. The mode control unit shifts, when a specific feature is detected on the feature detection mode, the mode to an imaging mode to acquire image information having a higher resolution than the resolution of the image information that is used for the feature detection.
