Shake Compensating Module Power Control via Periodic Disable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image capture devices consume significant power when continuously enabling image shake suppression, leading to reduced battery life due to prolonged activation of image stabilization features.
Innovation Solution
A control system that temporarily disables the image shake compensating module during data loading and automatically re-enables it after a specific period, optimizing power usage without affecting image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shake compensating module is continuously enabled to suppress image blur, then image quality is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic action by enabling the shake compensating module only during specific periods (when the shutter control element is in the first operating stage or after a predetermined time) and disabling it during other periods (when the shutter control element is in the second operating stage and before the predetermined time elapses). This periodic enablement strategy reduces power consumption while maintaining image quality when needed.
Solution Approach 2:
The patent applies dynamics by making the shake compensating module's operational state changeable rather than fixed. The control unit dynamically adjusts the module's enablement status based on the shutter control element's operating stage and time conditions, optimizing the balance between image quality and power consumption.
2Duration of action of moving object
If the shake compensating module is disabled to save power, then power usage is extended, but image shake suppression capability is lost
Solution Approach 1:
The patent uses periodic action to alternately enable and disable the shake compensating module based on time conditions. The module is disabled during image capture (when shutter control element is in second operating stage) to save power, then automatically re-enabled after a predetermined time to restore shake suppression capability, thus extending battery life while maintaining functionality.
Solution Approach 2:
The patent implements preliminary action by setting a predetermined time period in advance. The control unit is configured to automatically re-enable the shake compensating module after this predetermined time elapses from when it was disabled, ensuring that shake suppression capability is restored before it is needed again for the next capture.

AI summary
A control system for compensating for image shake of an image capture device is provided, including a shake compensating module, a shake compensating switch, a control unit, and a shutter control element operated between a first operating stage and a second operating stage. The shake compensating switch is switched between an active state to enable the shake compensating module and an inactive state to disable the shake compensating module. The control unit enables the shake compensating module when the shake compensating switch is in the active state. The control unit produces a reset signal to disable the shake compensating module when the shutter control element is in the second operating stage before the shake compensating switch is switched to the inactive state. The control unit enables the shake compensating module after a specific period of time from when the shake compensating module was disabled.
