Camera System Synchronous Asynchronous Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems require synchronization between the camera body and interchangeable lens for all operations, which is inefficient as not all processes need to be synchronized, leading to suboptimal processing efficiency.
Innovation Solution
A camera system with a synchronizing signal generator and controller in the camera body that can switch the interchangeable lens between synchronous and asynchronous modes, allowing synchronization only when necessary, enabling the camera body to focus on its own control during asynchronous operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If synchronization control is performed for all operations between camera body and interchangeable lens, then operational coordination is ensured, but processing efficiency deteriorates due to unnecessary synchronization overhead
Solution Approach 1:
The patent implements dynamic mode switching between synchronous and asynchronous operation modes. The lens controller changes its operational characteristics based on the current mode: in synchronous mode, it coordinates with the camera body using timing signals; in asynchronous mode, it operates independently. This dynamic adaptability resolves the contradiction by applying synchronization only when necessary, improving processing efficiency while maintaining operational coordination when needed.
2Reliability
If synchronous mode is used for all lens operations, then coordination with camera body is maintained, but lens controller freedom deteriorates due to timing signal restrictions
Solution Approach 1:
The system dynamically switches between synchronous and asynchronous modes based on operational requirements. During image capture, synchronous mode ensures reliable coordination between camera body and lens. During other operations like menu display or settings adjustment, asynchronous mode provides lens controller freedom without affecting operational reliability. This resolves the contradiction by adapting the coordination level to the specific operational context.
3Productivity
If asynchronous mode is used for all lens operations, then processing efficiency improves, but operational coordination deteriorates when synchronization is required
Solution Approach 1:
The patent implements dynamic mode selection where the system transitions to synchronous mode when image capture is detected, ensuring synchronization reliability at critical moments. During non-capture operations, it operates in asynchronous mode to maximize processing efficiency. This dynamic adaptation resolves the contradiction by applying synchronization only when reliability is critical, not continuously.

AI summary
The camera body includes a synchronizing signal generator that generates a synchronizing signal, a body controller that controls the camera body and generates a command to control the interchangeable lens. The body controller performs control to send the interchangeable lens a command to set the interchangeable lens to a synchronous mode in which operation of the interchangeable lens is controlled in synchronization with the synchronizing signal and a command to set the interchangeable lens to an asynchronous mode which is a mode other than the synchronous mode. The interchangeable lens includes a lens controller that controls the operation of the interchangeable lens. The lens controller controls the operation of the interchangeable lens in the synchronous mode or the asynchronous mode according to the command received from the camera body.
