Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing shake correction devices for imaging apparatuses have a complex structure due to multiple moving components, which increases the number of components and hinders simplification, while also not effectively reducing the weight of the movable body.
Innovation Solution
A control device and method that allows a moving body to move in two or more directions, controlled by a controller setting control values based on the initial and instructed positions, simplifying the structure and reducing the weight of the movable body by integrating the movement control within the imaging apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If multiple moving bodies are provided to apply driving forces in different directions, then the movable body weight is reduced, but the number of components increases and structure simplification is hindered
Solution Approach 1:
The patent merges multiple moving bodies into a single integrated movable body that receives driving forces from multiple actuators. The control device integrates the control logic for multiple actuators into a unified system that coordinates their operations, thereby reducing the number of separate components while maintaining the ability to apply multi-directional driving forces effectively.
Solution Approach 2:
The single movable body is designed to perform multiple functions by receiving driving forces from multiple actuators in different directions. The control device implements multi-functionality by coordinating these actuators to achieve various movement patterns and shake correction operations, eliminating the need for separate moving bodies for each function.
2Weight of moving object
If multiple moving bodies are used to enable movement in two or more directions, then weight reduction is achieved, but the number of components increases
Solution Approach 1:
The patent combines multiple moving bodies into one integrated movable body structure. Instead of having separate moving bodies for different directions, a single movable body is designed with multiple contact points where different actuators can apply driving forces, thereby reducing the total number of components while enabling multi-directional movement.
Solution Approach 2:
The control device segments the control functions for different actuators and directions into a coordinated control system. This allows the single movable body to be controlled in multiple directions through a unified control architecture, reducing component count while maintaining functional capability.
3Device complexity
If a single movable body is controlled with integrated movement control, then the structure is simplified, but control accuracy must be maintained
Solution Approach 1:
The control device incorporates feedback mechanisms that monitor the position and movement state of the single movable body. Based on this feedback, the control device adjusts the driving forces from multiple actuators in real-time, ensuring high control accuracy is maintained despite the simplified single-body structure. The feedback loop compensates for any deviations and maintains precise control.
Solution Approach 2:
The control device implements dynamic control strategies that adapt to the real-time state of the movable body. By continuously adjusting control parameters and coordinating actuator operations based on current conditions, the system maintains high control accuracy while benefiting from the structural simplicity of a single movable body.

AI summary
The present technology relates to a control device, a controlling method, and an imaging apparatus that make it possible to reduce a weight of a movable body while simplifying a structure and to improve control accuracy. A moving body that moves in two or more directions, and a controller that controls movement of the moving body are provided. The controller sets a control value directed to controlling of the movement of the moving body on the basis of an initial position of the moving body and an instructed position of the moving body. A parameter directed to setting of the control value is set on the basis of the initial position and the instructed position. The present technology is applicable, for example, to a shake correction device that corrects a hand shake of an imaging apparatus or a technique that achieves super-resolution by shifting a sensor to capturing a plurality of images.
