Intermediate Accessory Apparatus Control Information Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing systems require complex resource-intensive processes to combine control information from interchangeable lenses and intermediate accessory apparatuses, lacking an efficient method for managing control information unique to each component.
Innovation Solution
An intermediate accessory apparatus with a storage unit for characteristic information and a processor that communicates state information between the interchangeable lens and camera body, allowing for efficient control information management and image capturing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the identified element combines control information from the interchangeable lens apparatus and intermediate accessory apparatus, then proper control of focusing, aperture diaphragm operation, and zooming is achieved, but resource consumption (hardware, software, and time) increases
Solution Approach 1:
The patent extracts the control information combining function from the camera body and relocates it to the intermediate accessory apparatus. The intermediate accessory apparatus now stores and transmits its own control information directly to the camera body, eliminating the need for the camera body to perform resource-intensive combining operations while maintaining accurate control of focusing, aperture, and zooming functions.
2Ease of operation
If the camera body controls accessory apparatuses and acquires control information from the interchangeable lens apparatus, then proper controls of focusing, aperture diaphragm operation, and zooming are performed, but the system requires complex processing to combine control information from multiple sources
Solution Approach 1:
The intermediate accessory apparatus acts as an intermediary between the interchangeable lens apparatus and the camera body. It receives control information from the lens, adds its own control parameters, and transmits the combined information to the camera body. This mediator approach simplifies the overall system architecture by distributing the combining function to a dedicated component rather than requiring complex processing in the camera body.
Solution Approach 2:
The patent segments the control information management function across multiple independent components: the interchangeable lens apparatus provides lens-specific control data, the intermediate accessory apparatus provides accessory-specific control data and performs initial combining, and the camera body executes final control based on received information. This segmentation reduces processing complexity at each stage compared to centralized combining.
3Adaptability or versatility
If an intermediate accessory apparatus is mounted between the camera body and interchangeable lens apparatus, then control information from both components can be considered, but resource-intensive combining processes are required
Solution Approach 1:
The intermediate accessory apparatus performs preliminary action by pre-processing and transmitting its control information to the camera body before the actual image capturing operation. By having the intermediate accessory apparatus prepare and transmit its control parameters in advance, the system avoids energy-intensive real-time combining operations during image capture, while still achieving full adaptability with multiple accessory types.

AI summary
An intermediate accessory apparatus configured to be detachably mounted between an interchangeable lens apparatus and an image pickup apparatus includes a storage configured to store characteristic information about a combined optical characteristic of the interchangeable lens apparatus and the intermediate accessory apparatus, the characteristic information being associated with state information indicating a state of the interchangeable lens apparatus, the state information being communicated via a first communication between the interchangeable lens apparatus and the image pickup apparatus, and a processor configured to receive identification information about the interchangeable lens apparatus from the image pickup apparatus, and transmit the characteristic information corresponding to the identification information to the image pickup apparatus, via a second communication between the intermediate accessory apparatus and the image pickup apparatus.
