Collapsible Lens Barrel State Detection and Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible lens barrels for imaging devices are not suitable for imaging when in the stored state, as focus is not achieved, image resolution is low, and optical aberrations occur, making it difficult for photographers to prepare for imaging effectively.
Innovation Solution
An imaging device with a camera body that attaches a lens barrel with a collapsible barrel, where a control unit displays information indicating the device's state when the lens barrel is detected in the stored state, allowing users to prepare for imaging by displaying setting information and enabling cooperative functions such as moving image recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a collapsible lens barrel is used to reduce size, then the lens barrel length is shortened when collapsed, but imaging cannot be performed in the collapsed state due to focus issues and optical aberration
Solution Approach 1:
The lens barrel is designed to be dynamically changeable between collapsed and extended states. The collapsible barrel allows the lens to transition from a compact stored state to an extended imaging state, enabling the same lens to serve both portability and imaging functions. This dynamic structure resolves the contradiction by making the lens barrel length adaptable rather than fixed.
Solution Approach 2:
The system performs preliminary detection of the lens barrel state (collapsed or extended) and accordingly displays appropriate information to the user. When the lens is in the collapsed state, the system proactively displays setting information and notifications about imaging unavailability, allowing the user to prepare before extending the lens for actual imaging.
2Ease of operation
If the lens barrel is manually collapsed for storage, then portability is improved, but the device cannot capture images with proper focus and resolution
Solution Approach 1:
The control unit acts as an intermediary between the lens barrel state and the display output. It detects whether the lens is collapsed or extended and mediates the information display accordingly - showing setting information when collapsed and through-images when extended. This intermediary function ensures that appropriate information is presented based on the operational state, resolving the contradiction between portability and imaging quality.
Solution Approach 2:
The system implements feedback by continuously monitoring the lens barrel state and providing corresponding visual feedback to the user through the display. When the lens is collapsed, the system feedbacks information indicating that imaging is not available and displays setting options. This feedback mechanism helps users understand the current operational limitations and take appropriate actions.
3Loss of information
If setting information is displayed when the lens is in stored state, then user preparation is enabled, but the display must be switched when the lens is extended
Solution Approach 1:
The display function operates continuously and adaptively based on the lens barrel state. Rather than requiring manual switching or creating interruptions, the display automatically continues to provide relevant information - showing setting information when collapsed and transitioning to through-images when extended. This continuous adaptive display eliminates unnecessary interruptions and maintains useful information flow throughout the operation.

AI summary
The present invention relates to an imaging device including a camera body configured to attach, to a barrel body, a lens barrel including a collapsible barrel in which a barrel holding at least one lens can be in a stored state and in an extended state by manual operation, and a control unit configured to perform control to execute a display of information indicating a state of the imaging device in a case where the lens barrel attached to the camera body is detected to be in the stored state.
