Image Pickup Apparatus Protocol Adaptation for External Display Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image pickup apparatuses fail to transmit appropriate settings of picked-up images to external apparatuses due to protocol mismatches, leading to potential display issues when the external apparatuses do not support the compression encoding systems or resolutions specified by the image pickup apparatus.
Innovation Solution
An image pickup apparatus that stores multiple protocols and their associated capability information, determines the protocol of incoming commands, and transmits the corresponding capability information to ensure compatibility with the external apparatuses, thereby presenting only supported compression encoding systems and resolutions to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image pickup apparatus transmits capability information using a fixed protocol regardless of the incoming command protocol, then the response structure is simple and fast, but the transmitted capability information may not be compatible with the external apparatus using different protocols
Solution Approach 1:
The patent implements dynamic protocol adaptation where the image pickup apparatus determines the protocol type of incoming commands and switches to the corresponding capability information transmission protocol. This allows the system to adapt its behavior based on the external apparatus's protocol requirements, ensuring compatibility while maintaining a unified internal structure.
Solution Approach 2:
The patent introduces a protocol determination unit as an intermediary that identifies the command protocol type and selects the appropriate capability information. This intermediary layer abstracts the protocol complexity from the core image pickup functions, allowing different protocols to coexist without complicating the fundamental image processing operations.
2Adaptability or versatility
If the image pickup apparatus stores multiple protocols and capability information, then protocol compatibility is improved, but the storage requirements and device complexity increase
Solution Approach 1:
The patent implements a universal capability information storage structure that can accommodate multiple protocols through a single standardized interface. The determination unit universally handles all protocol types by routing to the appropriate capability information, allowing one system to serve multiple external apparatuses with different protocols without requiring separate dedicated systems for each protocol.
Solution Approach 2:
The patent pre-stores capability information for multiple protocols in advance, allowing the image pickup apparatus to quickly respond to external apparatuses regardless of their protocol type. This preliminary preparation eliminates the need for real-time protocol translation or complex on-the-fly generation of capability information.
3Productivity
If the image pickup apparatus uses a unified response structure for all protocols, then the processing is simplified and faster, but external apparatuses using protocols incompatible with the response structure cannot display the picked-up image
Solution Approach 1:
The patent implements dynamic response structure selection where the capability information transmission protocol matches the incoming command protocol type. This dynamic adaptation ensures that the response structure is always compatible with the external apparatus's capabilities, preventing display failures while maintaining efficient processing through direct protocol matching.

AI summary
An image pickup apparatus includes a storage unit configured to store a first protocol and a first capability information in a memory, the first capability information being associated with the first protocol as a capability information and also store a second protocol and second capability information in the memory, the second capability information being associated with the second protocol as the capability information, a reception unit configured to receive a command for requesting the capability information from the external apparatus via the network, a determination unit configured to determine whether the received command is in conformity to the first protocol or the second protocol, a reading unit configured to read out the first or second capability information associated with the protocol determined by the determination unit from the memory, and a transmission unit configured to transmit the read capability information to the external apparatus via the network.
