Camera Shutter Delay Mechanism for Hand Shake Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image stabilization cameras are costly and complex due to their mechanical structures and vibration sensing circuits, which are not effectively adapted to individual hand shake patterns of photographers.
Innovation Solution
A camera system that delays the shutter activation based on user-set stabilization time, detected through a trigger signal, to compensate for hand shake, using a module that records the trigger time and generates a shutter drive signal after a predetermined delay, thereby reducing the need for expensive compensation hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a vibration sensing circuit and optical compensation system are used for image stabilization, then image quality is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts and removes the complex vibration sensing circuit and optical compensation system from the camera. Instead, it uses a simple timing-based approach where the shutter is controlled to open after a predetermined delay period following detection of hand shake, eliminating the need for expensive stabilization hardware while maintaining image quality
Solution Approach 2:
The patent replaces the mechanical vibration compensation system with an electronic timing control system. Rather than using mechanical sensors and optical elements to counteract vibration, the system uses electronic timing to delay shutter activation until hand shake subsides, substituting a simple electronic control mechanism for complex mechanical stabilization
2Manufacturing precision
If a vibration sensing circuit and compensation hardware are implemented, then image stabilization is achieved, but manufacturing cost increases
Solution Approach 1:
The patent employs inexpensive electronic timing components and software-based hand shake detection instead of expensive vibration sensing circuits and optical compensation hardware. The solution uses readily available microcontroller timing functions and simple delay mechanisms that are far cheaper to manufacture while achieving the same image stabilization effect
3Manufacturing precision
If a generic image stabilization mechanism is used, then image quality is improved, but adaptability to individual hand shake patterns decreases
Solution Approach 1:
The patent implements a dynamic adaptation mechanism where the camera records and analyzes hand shake characteristics for each individual user over multiple shooting sessions. The system adjusts the shutter delay timing based on each user's specific hand shake patterns, transforming a static generic stabilization approach into a dynamic personalized system that adapts to individual users

AI summary
An image stabilization method for a camera is provided. The image stabilization method controls the shutter of the camera. The image stabilization method, according to the present invention, first detects whether a trigger signal has been inputted, wherein the trigger signal is inputted by a user and starts an image capturing process. Next, the time when the trigger signal was inputted is detected and recorded as a first time. Afterwards, a stabilization time is delayed based upon the first time. Finally, a drive signal is generated when the stabilization time ends, wherein the drive signal drives the shutter to turn on for executing the image capturing process.
