Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of new and old network camera systems poses challenges due to inconsistencies in coding methods, requiring an imaging apparatus that maintains backward compatibility while supporting new coding standards, such as JPEG2000 and H.265, without increasing the number of commands significantly.
Innovation Solution
An imaging apparatus equipped with an imaging unit, coding unit, reception unit, conversion unit, and storage unit that can receive and convert coding method setting commands, allowing it to automatically switch between different coding methods like JPEG, H.264, and H.265, ensuring compatibility with both old and new client devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new network camera apparatus supports new coding methods (e.g., JPEG2000 or H.265) to satisfy enhanced image quality and compression needs, then adaptability is improved, but device complexity increases due to the need to maintain backward compatibility with old coding methods and protocols
Solution Approach 1:
The patent introduces a conversion unit that acts as an intermediary between old and new coding methods. This conversion unit automatically converts coding method information between different coding standards, enabling the imaging apparatus to communicate with both old and new client apparatuses using a unified command structure, thereby reducing system implementation complexity while maintaining support for multiple coding methods
Solution Approach 2:
The imaging apparatus is designed with multi-functionality to handle both old and new coding methods through a single unified interface. The apparatus can receive coding method setting commands in a unified format and automatically adapt to the appropriate coding standard, making it compatible with diverse client apparatuses without requiring separate command structures for each coding method
2Adaptability or versatility
If multiple coding method setting commands are supported to ensure compatibility with both old and new client apparatuses, then adaptability is improved, but command complexity increases
Solution Approach 1:
The patent implements a universal command structure where a single coding method setting command can function across multiple coding standards. The imaging apparatus receives commands in a unified format and internally adapts them to the appropriate coding method, eliminating the need for separate command structures for each coding standard and reducing overall command complexity
3Ease of operation
If the imaging apparatus automatically converts coding method information between different coding standards, then ease of operation is improved, but processing time increases
Solution Approach 1:
The imaging apparatus performs preliminary conversion of coding method information when receiving setting commands, converting the information in advance to the appropriate coding standard before actual image encoding begins. This preliminary action ensures that the conversion processing is completed before critical operations, minimizing the impact on real-time performance while maintaining ease of operation

AI summary
An imaging apparatus can communicate with an external apparatus via a network. The imaging apparatus includes an imaging unit configured to capture an image of a target object, a coding unit configured to compress a video captured by the imaging unit, and a reception unit configured to receive at least two types of coding method setting commands, which can be used to set a coding method to be used by the coding unit, via the network. The imaging apparatus further includes a conversion unit configured to automatically convert coding method information to be set by coding setting command into at least one type of different coding method information, and a storage unit configured to store coding method information to be set by the coding setting command and the coding method information converted by the conversion unit.
