Blur Correction Adjustment for Mechanical and Electronic Shutter Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image pickup apparatuses lack the capability to selectively use either an electronic shutter or a mechanical shutter for exposure control, which limits their ability to provide appropriate blur correction depending on the shutter used.
Innovation Solution
An image pickup apparatus with a selection unit and controller that allows for the selection between a mechanical shutter mode and an electronic shutter mode, outputting specific blur correction information to a blur correction unit to perform appropriate correction operations based on the selected shutter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both electronic shutter and mechanical shutter are provided for selective use, then shutter selection flexibility is improved, but device complexity increases
Solution Approach 1:
The image pickup apparatus is designed with both electronic shutter and mechanical shutter units, allowing the system to perform exposure control through multiple mechanisms. The controller selectively activates either the electronic shutter or mechanical shutter based on shooting conditions, providing universal exposure control capability that adapts to different requirements while managing complexity through intelligent selection rather than permanent dual-operation.
2Measurement precision
If blur correction value is changed depending on shutter type, then image blur correction accuracy is improved, but control complexity increases
Solution Approach 1:
The controller changes the blur correction value parameter based on which shutter type is being used. When the mechanical shutter is activated, a specific blur correction value is applied; when the electronic shutter is used, a different blur correction value is applied. This parameter adaptation allows the blur correction device to maintain high accuracy for each shutter type without requiring complex structural modifications, as the adjustment is achieved through software-controlled parameter variation rather than hardware complexity.

AI summary
An image pickup apparatus having removably attached thereto a lens apparatus including a blur correction unit includes a selection unit configured to select a first mode in which a mechanical shutter is used to start exposure or a second mode in which an electronic shutter is used to start exposure; and a controller configured to output information indicating the start of exposure to the lens apparatus. The controller changes the information indicating the start of exposure depending on whether the first mode or the second mode is selected to control the lens apparatus to perform different blur correction operations.
