Image Processing Device Remote Control via Web Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for image processing devices require large memory capacity to store dedicated command programs, which can occupy significant memory space and increase communication load.
Innovation Solution
An image processing device with a communication interface, touch screen, and controller that generates and sends screen data to an information processing device for displaying and switching screens, allowing remote control operations without the need for dedicated command programs, using HTTP protocols and CGI scripts to manage user inputs and screen updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large dedicated command program is stored in the image processing device for remote control, then remote control functionality is achieved, but memory capacity is significantly occupied
Solution Approach 1:
The patent extracts the dedicated command program from the image processing device and replaces it with a web server that serves standard web pages. The remote control interface is moved to the information processing device (terminal), while the image processing device only needs to provide screen data through standard web protocols, eliminating the need for large dedicated control programs in its memory.
Solution Approach 2:
The patent applies universality by using standard web protocols (HTTP) and common web technologies (HTML, CSS, JavaScript) that can be accessed by any information processing device with a web browser. This replaces specialized remote control protocols with universal web standards, allowing the same web server to serve multiple functions including display, input reception, and control.
2Adaptability or versatility
If a large dedicated command program is stored in the image processing device, then remote control operations are enabled, but communication load increases
Solution Approach 1:
The patent uses copying by transmitting screen data as standard web pages (HTML, CSS, JavaScript) from the image processing device to the information processing device. The terminal device then renders these web pages locally to display the interface and handle user interactions, reducing the communication load compared to transmitting and executing dedicated control programs.
3Ease of operation
If dedicated command programs are used for remote control, then device control is achieved, but device complexity increases
Solution Approach 1:
The patent replaces the mechanical system of dedicated control programs with a web-based system. Instead of embedding specialized control software in the image processing device, it uses a web server that communicates through standard HTTP protocols, which can be accessed by any device with a web browser, thereby reducing device complexity.

AI summary
An image processing device may display a first display screen including a first image on a touch screen. The first image may be for accepting a display switching instruction to switch the first display screen to a second display screen. The image processing device may generate first screen data which enables a display of the information processing device to display the first display screen. The image processing device may send the generated first screen data in a case where first request information is received from the information processing device. The image processing device may receive coordinate information indicating a position within the first display screen where an input operation has been inputted. The image processing device may switch to the second display screen associated with the first image in a case where the position indicated by the coordinate information is within the display area of the first image.
