Operation Key Display Layout for Restricted Image Processing Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing apparatuses face challenges in improving user operability for function selection due to complex settings and limitations in managing function restrictions, particularly when user authentication is required.
Innovation Solution
The apparatus includes a controller that manages function restrictions by using a register to control the display of operation keys in multiple display regions, allowing for the restriction of certain functions in a variable region while maintaining operability through a fixed region, and employs a prohibited function registration program to simplify administrative settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operation keys are displayed in multiple display regions, then function selection operability is improved, but device complexity increases
Solution Approach 1:
The operation screen is divided into multiple display regions (first display region and second display region) with distinct functions. The first display region shows operation keys that can be selected, while the second display region shows operation keys that are restricted based on user authentication status. This segmentation allows the system to manage different levels of access without increasing overall complexity.
Solution Approach 2:
Different display regions have different display characteristics for operation keys. In the first display region, operation keys are displayed with full functionality, while in the second display region, operation keys are displayed with restriction information indicating limited access. This local differentiation improves operability by clearly indicating which functions are available to which users.
2Ease of operation
If function restriction settings are simplified, then ease of operation is improved, but reliability of function control may worsen
Solution Approach 1:
The system automatically determines which operation keys to display in which display regions based on user authentication results. The controller autonomously manages the display configuration without requiring complex manual settings from administrators. This self-service approach simplifies operation while maintaining reliable function control through automated authentication-based restrictions.
3Reliability
If operation keys are restricted in certain display regions, then function control is improved, but loss of information increases
Solution Approach 1:
The second display region acts as an intermediary between the full function list and the restricted function list. It displays operation keys with restriction information as a mediator layer, providing users with information about available functions while maintaining the restriction mechanism. This prevents complete information loss while preserving control.

AI summary
An image processing apparatus includes a display that displays, on an operation screen, operation keys associated with functions related to image processing and receiving an instruction to select a function to be used; one or more controllers that control displaying the operation key on the operation screen; and a register that registers the function with restriction on use, the operation screen includes a first display region capable of displaying the operation key and a second display region different from the first display region, and the one or more controllers control displaying the operation key in the first display region and the second display region with respect to the function registered in the register.
