Wireless Endoscope Imaging Mode Switching for Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless endoscopes face a challenge in maintaining portability due to increasing battery weight as power capacity increases, and existing technologies do not effectively manage power consumption to balance imaging quality and battery life.
Innovation Solution
An imaging apparatus that operates in two modes: a power-saving mode with reduced power consumption and a normal mode with increased power usage, adjusting imaging sensitivity based on image brightness to determine if the device is inserted into an observation target, thereby optimizing power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the battery capacity is increased to extend operation time, then the power consumption capability is improved, but the weight of the wireless endoscope increases
Solution Approach 1:
The imaging apparatus dynamically adjusts its operation mode based on environmental conditions. The processor switches between a first operation mode (higher power consumption) and a second operation mode (lower power consumption) by evaluating image brightness. This dynamic adaptation allows the system to extend operation time without requiring a larger battery, thereby avoiding increased weight.
2Duration of action of moving object
If the power consumption is reduced to extend battery life, then the operation duration is improved, but the imaging quality may deteriorate
Solution Approach 1:
The system changes operational parameters (power consumption level) based on environmental conditions. When the image brightness exceeds the threshold, the processor switches to the second operation mode with reduced power consumption. When brightness is at or below the threshold, it operates in the first mode with higher power consumption to maintain imaging quality. This conditional parameter adjustment resolves the contradiction between battery life and imaging quality.
3Measurement precision
If the imaging sensitivity is increased to improve detection accuracy in dark environments, then the measurement precision is improved, but the power consumption increases
Solution Approach 1:
The system applies different imaging sensitivity levels based on local environmental conditions (image brightness). Instead of maintaining high sensitivity continuously, the processor adjusts sensitivity locally according to whether the brightness threshold is exceeded. This localized adaptation improves detection accuracy when needed while conserving power in adequate lighting conditions.

AI summary
An imaging apparatus includes an imaging device and a processor. The processor is configured to determine brightness of an image when the imaging apparatus is operating in a second operation mode. The processor is configured to increase imaging sensitivity of the imaging device when the processor determines that the brightness is darker than or equal to a first brightness. The processor is configured to cause the imaging apparatus to operate in a first operation mode when the processor determines that the brightness is darker than or equal to a second brightness darker than the first brightness after the processor increases the imaging sensitivity.
