Remote Screen Operation Filtering for Image Processing Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In remote control methods using Virtual Network Computing (VNC) for image processing apparatuses, there is an issue where screen transitions are performed differently from the user's intention when a drag operation is received by both the terminal and the image processing apparatus, especially when the terminal displays an enlarged screen.
Innovation Solution
The method involves displaying a screen on a terminal corresponding to the image processing apparatus's operation screen and transmitting operation information only when the operation is intended for the default screen state, avoiding transmission during operations like drag or screen enlargement intended for the terminal's display adjustments.

Engineering Contradiction Analysis
1Ease of operation
If the terminal transmits operation information to the image processing apparatus when a drag operation is received, then the image processing apparatus can perform screen transition processing, but the processing will be different from the user's intention when the terminal displays an enlarged screen
Solution Approach 1:
The terminal determines whether to transmit operation information based on feedback about the current display state (enlarged or not). When the display state indicates an enlarged screen, the terminal withholds transmission of drag operation information, preventing unintended screen transitions at the image processing apparatus while still allowing the terminal to perform its own display adjustments.
2Illumination intensity
If the terminal displays an enlarged screen for better visibility, then the user can see the operation screen more clearly, but drag operations on the terminal will trigger unintended screen transitions on the image processing apparatus
Solution Approach 1:
The terminal applies different operation handling rules based on the local display state. When the screen is enlarged, drag operations are handled locally for display adjustment purposes only. When the screen is not enlarged, drag operations are transmitted to the image processing apparatus for screen transition. This local quality differentiation resolves the conflict between improved visibility and unintended side effects.

AI summary
In a case where an image processing apparatus and a terminal display screens in an associated manner, if the terminal receives a user operation in a state where an enlarged screen is displayed only on the terminal, and the terminal transmits information about the operation as it is to the image processing apparatus, processing not intended by the user may possibly be performed. Therefore, when the terminal receives a user operation in a state where an enlarged screen is displayed only on the terminal, the terminal does not transmit the operation information as it is to the image processing apparatus.
