Imaging Apparatus Standby Power Control via Dual Engine State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses consume power unnecessarily while displaying a live view image, as both the front engine and back engine operate continuously, even in standby mode, leading to inefficient power usage.
Innovation Solution
The imaging apparatus includes a control unit that restricts power supply to the second processing circuit in standby mode and lifts the restriction upon an image capturing instruction, allowing the main engine to conserve power until an image is recorded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If both the front engine and back engine operate continuously while displaying a live view image, then the image processing capability is maintained, but the power consumption increases
Solution Approach 1:
The patent applies dynamics by transitioning the back engine between different operational states (standby state with restricted power supply and operational state with full power supply) based on the imaging mode. This dynamic state change allows the system to maintain image processing capability when needed while reducing power consumption during standby, resolving the contradiction between reliability and energy use.
Solution Approach 2:
The patent implements preliminary action by pre-configuring the back engine to be in a standby state with restricted power supply before an imaging operation is initiated. When an imaging mode is detected, the power supply restriction is lifted in advance to ensure the back engine is ready for immediate operation, thus maintaining reliability while minimizing unnecessary power consumption during the standby period.
2Use of energy by moving object
If the back engine is placed in standby mode with restricted power supply, then power consumption is reduced, but the response time for image recording may increase
Solution Approach 1:
The patent applies preliminary action by detecting the imaging mode in advance and proactively lifting the power supply restriction to the back engine before the actual image recording begins. This ensures that the back engine transitions from standby to operational state without delay, maintaining fast response time while still benefiting from reduced power consumption during the standby period when no imaging is performed.
Solution Approach 2:
The patent implements feedback by continuously monitoring the imaging mode and using this information to dynamically adjust the power supply to the back engine. When an imaging mode is detected, the system provides feedback to lift the power restriction, ensuring the back engine responds promptly. This feedback mechanism resolves the contradiction by ensuring the system reacts quickly to imaging requirements while maintaining energy efficiency during non-imaging periods.
