Exchangeable Lens Initialization via Dual Transmission Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The camera system experiences a time lag during startup due to the initialization of multiple units at the camera head, delaying the camera head initialization process.
Innovation Solution
The exchangeable lens includes a mount unit, drive target members, an initialization unit, an initialization status transmission unit, and a drive condition transmission unit, which execute and transmit initialization statuses and drive conditions via distinct transmission paths over predetermined cycles, allowing for efficient communication and control of the camera body's startup process.

Engineering Contradiction Analysis
1Reliability
If multiple units are started up at the camera head simultaneously, then all units can be initialized, but a time lag occurs that delays the camera head initialization process
Solution Approach 1:
The patent divides the initialization process into two separate communication paths: a first transmission path for initialization status information and a second transmission path for drive condition information. This segmentation allows the camera body to monitor initialization progress and receive drive conditions independently, reducing the overall initialization time by eliminating sequential dependencies.
Solution Approach 2:
The exchangeable lens transmits initialization status information proactively through the first transmission path before all initialization is complete. This allows the camera body to prepare for subsequent operations in advance, reducing the waiting time after initialization completes. The drive condition information is also transmitted preliminarily through the second path to enable early preparation.
2Speed
If initialization status is transmitted frequently, then the camera body can detect completion quickly, but communication load increases
Solution Approach 1:
The patent implements periodic transmission of initialization status information at predetermined first cycles through the first transmission path, and periodic transmission of drive condition information at predetermined second cycles through the second transmission path. This periodic approach balances detection speed with energy efficiency, as the system only communicates when status changes occur or at scheduled intervals, rather than continuously.
Solution Approach 2:
The camera body receives initialization status information and uses it to determine when initialization is complete, then stops requesting further status updates. This feedback mechanism allows the system to reduce communication frequency once initialization is complete, lowering energy consumption while maintaining fast detection during the critical initialization phase.

AI summary
An exchangeable lens includes: a mount unit at which a camera body is detachably engaged; a plurality of drive target members, conditions of which change as a drive force is applied thereto; an initialization unit that executes initialization processing for each of the plurality of drive target members; an initialization status transmission unit that transmits initialization statuses, each indicating a status of the initialization processing executed for one of the drive target members, to the camera body via a first transmission path over predetermined first cycles; and a drive condition transmission unit that transmits a drive condition of at least one drive target member among the plurality of drive target members to the camera body via a second transmission path different from the first transmission path over predetermined second cycles different from the predetermined first cycles.
