Image Processing Authentication Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing apparatuses face challenges in operating with multiple obtaining devices using authentication information, as they lack the capability to effectively manage and utilize authentication data from both internal and external sources.
Innovation Solution
An image processing apparatus is designed with internal and external obtaining devices, a communication unit, and a controller that determines authentication permissions based on reference information, allowing the apparatus to operate using authentication information from either source, with the ability to compare and select the most suitable device for authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the image processing apparatus uses both internal and external obtaining devices for authentication, then the adaptability and versatility are improved, but the device complexity increases
Solution Approach 1:
The controller is designed to universally handle authentication from multiple sources (internal obtaining device and external obtaining device) using a unified determination processing framework. The controller can select which obtaining device to use based on the operational state, making the system multi-functional without requiring separate processing paths for each authentication source.
Solution Approach 2:
The system dynamically adjusts its authentication approach based on the operational state. When the external obtaining device is mounted, the controller uses external authentication; when it is not mounted, the controller switches to internal authentication. This dynamic adaptation resolves the contradiction by making the system flexible rather than statically complex.
2Reliability
If the apparatus always powers on both internal and external obtaining devices, then the reliability of authentication is improved, but the power consumption increases
Solution Approach 1:
Instead of continuously powering both obtaining devices, the system periodically or conditionally activates the appropriate device based on whether the external obtaining device is mounted. This periodic/conditional operation maintains authentication reliability when needed while reducing power consumption during normal operation.
Solution Approach 2:
The system applies different operational states to different components based on local conditions. When the external obtaining device is mounted, only that device is activated for authentication; when it is not mounted, the internal obtaining device is activated. This localized quality control ensures reliability where needed while minimizing overall power consumption.

AI summary
An image processing apparatus includes an internal obtaining device configured to obtain authentication information, a communication unit configured to perform communication with an external obtaining device that is configured to obtain authentication information, an image processing unit configured to execute at least one of image reading and image formation, and a controller configured to execute determination processing including granting a permission for executing image processing by the image processing unit when the controller determines that the authentication based on the authentication information obtained from the internal obtaining device and first reference information is successful, and granting the permission for executing the image processing when the controller determines that the authentication based on the authentication information obtained from the external obtaining device and second reference information is successful, the second reference information being different from the first reference information.
