Image Processing Apparatus Setting History Prohibition Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image processing apparatuses face challenges in preventing erroneous or unauthorized use of setting histories while maintaining usability, as they cannot track or display past job execution details effectively.
Innovation Solution
An image processing apparatus with a job executor, setter, and controller that displays and controls job execution based on setting histories, determining whether to restrict jobs based on prohibition settings, ensuring that prohibited setting histories are not used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If setting histories related to prohibited jobs are hidden to prevent erroneous or unauthorized use, then security is improved, but usability deteriorates because users cannot check or track past job execution details
Solution Approach 1:
The patent segments the setting history display functionality into two distinct modes: a first display that shows setting histories including prohibited ones for tracking and auditing purposes, and a second display that excludes prohibited setting histories for normal user operations. This segmentation allows the system to simultaneously provide comprehensive history tracking while preventing unauthorized job execution, thereby resolving the contradiction between security and usability.
2Ease of operation
If all setting histories are displayed to enable tracking of past jobs, then usability is improved, but security deteriorates because prohibited jobs may be executed
Solution Approach 1:
The patent implements dynamic control over setting history display based on user context and system state. The display adaptively switches between showing all setting histories (including prohibited ones) and excluding prohibited ones, depending on whether the user is in a tracking/audit mode or a normal operation mode. This dynamic behavior allows the system to provide full visibility when needed for tracking while automatically preventing unauthorized execution during normal operations.

AI summary
An image processing apparatus includes a job executer that executes a job related to image processing, based on a setting history, a setter that sets prohibition on use of the setting history, a display that displays the setting histories including a setting history on which the prohibition is set, and a controller that controls execution of a job, based on the displayed setting histories, and, in executing the job based on the setting history, the controller determines whether to restrict execution of the job, based on a result of determination on whether the setting history is the setting history on which the prohibition is set.
