Imaging Device Shake Correction Control During Movement

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Imaging devices may fail to capture desired images due to shake correction interference during changes in position or orientation, as existing systems do not effectively manage shake correction functions during such movements.

Innovation Solution

A control device with a detection unit that disables the shake correction function before the imaging device starts changing position or orientation, and re-enables it after the movement is completed, ensuring stable image capture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If shake correction is enabled during position or orientation changes, then image stability is improved, but image capture reliability deteriorates due to interference with movement

Engineering Contradiction:

Improveimage stabilityVSAvoidimage capture reliability

Core Design Contradiction:

Stability of the object's compositionVSReliability

Solution Approach 1:

The control unit disables the shake correction function in advance before the imaging device changes position or orientation, based on detection of a driving command. This preliminary action prevents shake correction interference from occurring during movement, ensuring reliable image capture while maintaining image stability when the device is stationary

Inventive Principle:

Principle #10Preliminary action

2Reliability

If shake correction is disabled during position or orientation changes, then image capture reliability is improved, but image stability deteriorates when stationary

Engineering Contradiction:

Improveimage capture reliabilityVSAvoidimage stability

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The shake correction function is dynamically controlled based on the operational state of the imaging device. The control unit switches between enabled and disabled states according to whether the device is moving or stationary, optimizing both image capture reliability during movement and image stability when stationary

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If shake correction function is continuously operated, then image stability is maintained, but energy consumption increases

Engineering Contradiction:

Improveimage stabilityVSAvoidenergy consumption

Core Design Contradiction:

Stability of the object's compositionVSUse of energy by moving object

Solution Approach 1:

The shake correction function operates periodically rather than continuously - it is enabled when the imaging device is stationary and disabled when movement is detected. This periodic operation maintains image stability when needed while reducing energy consumption during movement phases

Inventive Principle:

Principle #19Periodic action

AI summary

A control device includes a memory storing a program and a processor coupled to the memory and configured to execute the program to detect a driving command supplied to a driving device that changes a position or an orientation of an imaging device, and disable a shake correction function of the imaging device before the driving device starts to change the position or the orientation of the imaging device corresponding to the driving command.
