Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interchangeable lens systems in digital cameras lack the level of control and coordination with the camera body, leading to suboptimal image quality and limited functionality compared to integrated lenses.
Innovation Solution
A system that establishes electronic communication between a removable lens assembly and a camera, exchanging capability information to match and enable functional features such as image focusing and motion stabilization, allowing the lens and camera to cooperate and provide enhanced imaging capabilities, including firmware and software updates via wireless protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an interchangeable lens system is used, then the lens can be removed and replaced, but the level of control and coordination with the camera body is reduced
Solution Approach 1:
The patent implements a feedback mechanism where the lens assembly and camera body continuously exchange capability information and operational status through wireless communication. The camera body receives capability information from the lens, matches functional features, and sends control commands back to the lens, which then feedbacks execution status. This closed-loop feedback system ensures reliable control and coordination even with interchangeable lenses.
Solution Approach 2:
The patent introduces a communication management module as an intermediary that mediates between the lens assembly and camera body. This intermediary establishes and manages the wireless communication link, exchanges capability information, matches functional features, and coordinates control commands, thereby bridging the gap between interchangeable lens and camera body to achieve integrated-level control.
2Adaptability or versatility
If wireless communication is established between lens assembly and camera, then functionality is enhanced, but device complexity increases
Solution Approach 1:
The patent implements a universal communication protocol that allows the lens assembly and camera body to exchange multiple types of information (capability information, control commands, status feedback) through a single wireless communication channel. The communication management module handles various functional features (image focusing, motion stabilization, etc.) through this unified interface, reducing the need for separate dedicated systems for each function.
3Adaptability or versatility
If capability information is exchanged between lens and camera, then functional features can be matched, but information loss occurs during transmission
Solution Approach 1:
The patent employs feedback mechanisms where the receiving party (camera body or lens assembly) acknowledges receipt of capability information and requests retransmission if information is lost or corrupted. The transmitting party sends capability information, waits for acknowledgment, and upon receiving a negative acknowledgment or timeout, retransmits the information to ensure complete and accurate data transfer.

AI summary
Implementations generally relate to communication between a lens assembly and a camera. In some implementations, a method includes establishing electronic communication between a lens assembly and a camera, wherein the lens assembly is removably attached to the camera. The method further includes exchanging capability information between the lens assembly and the camera, wherein the capability information includes one or more functional features. The method further includes matching one or more of the functional features that both the lens assembly has and that the camera has. The method further includes enabling the lens assembly and the camera to cooperate in providing functional features based at least in part on the matching of one or more of the functional features.
