Image Stabilization Control Using Temperature-Based Correction Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing devices struggle to accurately correct image shake due to temperature variations between the image capturing device main body and the imaging lens, as existing techniques do not account for temperature-based detection accuracy changes.
Innovation Solution
An image capturing device with a control unit that calculates and adjusts the correction share ratio for both the imaging lens and the image capturing device main body based on their respective temperature deviations, ensuring accurate shake correction by optimizing the contribution of each unit according to their temperature stability.

Engineering Contradiction Analysis
1Reliability
If temperature-based correction amount calculation is not implemented, then device complexity is reduced, but image shake correction accuracy deteriorates under varying temperature conditions
Solution Approach 1:
The patent applies parameter changes by using temperature as a variable parameter to dynamically adjust the correction amount. The calculation unit changes the correction parameters based on detected temperature values, allowing the shake correction system to adapt to temperature variations without adding complex hardware structures.
Solution Approach 2:
The patent implements feedback by using temperature detection results to adjust correction amounts. The system detects temperature, calculates the appropriate correction amount based on this temperature feedback, and applies the correction, creating a closed-loop control system that improves accuracy under varying thermal conditions.
2Measurement precision
If temperature-based detection accuracy adjustment is not implemented, then device complexity is reduced, but detection precision deteriorates at extreme temperatures
Solution Approach 1:
The patent changes detection parameters based on temperature. The calculation unit adjusts detection accuracy parameters according to detected temperature values, compensating for temperature-induced detection errors without requiring complex hardware modifications or multiple sensors.

AI summary
An image capturing device includes: an imaging lens; an image capturing device main body including an imaging element that captures an optical image transmitting through the imaging lens; a first correction unit that performs correction of an image shake by a correction lens; and a second correction unit that performs correction of the image shake by the image capturing device main body. The image capturing device performs a control of causing the first correction unit and the second correction unit to share and correct the image shake and calculates a correction amount of each of the first correction unit and the second correction unit according to at least one of a temperature of the imaging lens or a temperature of the image capturing device main body in a case where correction of the image shake is performed by the first correction unit and the second correction unit.
