Imaging Device Notification Timing to Prevent Exposure Blur
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices face issues with image blurring due to vibrations during exposure periods, especially in continuous shooting modes, and there is a need for more effective notification methods beyond vibration and sound to inform users about image capture.
Innovation Solution
The imaging device includes a control unit that coordinates notification through vibration or other means in periods separate from exposure, adjusting timing and intensity to avoid overlap with exposure, and provides additional notification modes like display changes to confirm image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If notification is performed through vibration in response to shutter operation, then user can recognize image capture completion, but image blurring occurs during exposure period
Solution Approach 1:
The control unit performs vibration notification before the exposure period starts, allowing the user to recognize the shutter operation acceptance without interfering with the actual image capture process. This preliminary timing ensures both effective user notification and image quality maintenance.
Solution Approach 2:
The system separates notification and exposure into distinct time periods, with vibration occurring in a period before exposure and no vibration during the exposure period. This periodic separation eliminates the harmful effect of vibration-induced blurring while maintaining notification effectiveness.
2Ease of operation
If vibration is performed during exposure period, then user feedback is provided, but image blurring occurs
Solution Approach 1:
Vibration notification is performed in advance before the exposure period begins, providing user feedback about shutter operation acceptance without introducing blurring during the critical image capture phase.
Solution Approach 2:
The notification function is extracted from the exposure period and placed in a separate pre-exposure period. This separation removes the harmful vibration effect during image capture while preserving the feedback function for the user.
3Loss of information
If multiple notification modes are added, then user awareness is improved, but device complexity increases
Solution Approach 1:
The control unit is designed to handle multiple notification modes (vibration, sound, display changes) through a single integrated control mechanism. This multi-functional approach allows diverse notification methods without proportionally increasing device complexity.

Function Achieved in This Case
This approach prevents image blurring and ensures users are informed about image capture without discomfort, maintaining high-quality image quality and user awareness during continuous shooting.
Implementation Method 1
an imaging element unit that is exposed to incident light and that outputs a captured image signal
Implementation Method 2
there is a possibility that blurring occurs in a recorded still image if the vibration is performed in an exposure period

AI summary
An imaging device includes an imaging element unit that is exposed to incident light and that outputs a captured image signal, a notification unit, and a control unit that performs control in such a way as to cause the notification unit to perform notification corresponding to still image capture exposure, which is performed by the imaging element unit to generate a still image in response to a still image capture instruction, in a period different from an exposure period of the still image capture exposure.
