Solution Overview

Problem

Existing imaging systems face challenges in accurately tracking and stabilizing target subjects within captured images, particularly due to vibrations and movements, which affect image quality and stability.

Innovation Solution

An imaging support device that calculates and adjusts the position of a target subject image using a combination of a revolution mechanism and a shake correction mechanism, based on in-image shift amounts, focal length, and pixel interval, to maintain image stability and tracking accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a shake correction mechanism is used to stabilize the target subject image, then image stability is improved, but the device complexity increases due to the combination of revolution mechanism and shake correction mechanism

Engineering Contradiction:
Improveimage stabilityVSAvoiddevice complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent combines a revolution mechanism and a shake correction mechanism into a unified position adjustment system. The revolution mechanism provides coarse position adjustment while the shake correction mechanism provides fine adjustment, merging two different correction approaches into one integrated system that achieves both broad coverage and precision.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The position adjustment function is segmented into two independent mechanisms: the revolution mechanism for large-range position changes and the shake correction mechanism for small-range precision adjustments. This segmentation allows each mechanism to operate optimally within its designated range, improving overall system performance.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If the position of the target subject image is adjusted using both revolution mechanism and shake correction mechanism, then tracking accuracy is improved, but the control complexity increases

Engineering Contradiction:
Improvetracking accuracyVSAvoidcontrol complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system dynamically switches between the revolution mechanism and shake correction mechanism based on the required adjustment magnitude. The control unit determines which mechanism to activate based on real-time position deviation, optimizing tracking accuracy while managing control complexity through adaptive decision-making.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses feedback from position detection to continuously monitor the target subject image position and adjust the operation of the revolution mechanism and shake correction mechanism accordingly. This closed-loop control ensures high tracking accuracy by constantly correcting position deviations.

Inventive Principle:
Principle #23Feedback

3Device complexity

If the shake correction mechanism operates with limited movable range, then the device structure is simplified, but the ability to track moving subjects is reduced

Engineering Contradiction:
Improvedevice structureVSAvoidtracking capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent merges the revolution mechanism with extended movable range and the shake correction mechanism with high precision into a coordinated system. The revolution mechanism compensates for the limited range of the shake correction mechanism, while the shake correction mechanism provides the precision needed for accurate tracking, together achieving both full coverage and high accuracy.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An imaging support device that supports imaging performed by an imaging apparatus includes an acquisition portion that acquires an in-image shift amount between a predetermined position in a captured image obtained by capturing an imaging region by an imaging element and a position of a target subject image showing a target subject, and a focal length of the imaging apparatus, a derivation portion that derives a movement amount required for moving the position of the target subject image to a specific position by a position adjustment portion which adjusts the position of the target subject image in the captured image, based on the in-image shift amount acquired by the acquisition portion, the focal length acquired by the acquisition portion, and information related to a pixel interval of pixels in the imaging element, and an output portion that outputs the movement amount derived by the derivation portion.
