Image Processing Device Offline Web Content via Code Image
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for multi-function peripherals cannot display web content using an embedded browser when the device is not connected to a network.
Innovation Solution
An image processing device that includes a display and is capable of displaying web content, even when not connected to a network, by generating a code image including access information and displaying it on the device's screen, allowing web content to be accessed and displayed on a different device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If web content is displayed using an embedded browser of a multi-function peripheral, then web content can be displayed on the device, but the device must be connected to a network which increases device complexity and restricts usage scenarios
Solution Approach 1:
The patent introduces a code image (QR code or barcode) as an intermediary element. Instead of directly displaying web content in the embedded browser which requires network connection, the system generates a code image containing access information that can be scanned by external devices. This intermediary allows users to access web content through their own devices without requiring the image processing device to be connected to the network, thus resolving the contradiction between web content display capability and network connection requirement.
2Reliability
If web content is displayed using an embedded browser, then web content can be accessed on the image processing device, but the system becomes dependent on network connectivity which reduces reliability in offline scenarios
Solution Approach 1:
The patent extracts the network dependency from the web content display process. Instead of requiring the image processing device to connect to the network to display web content, the system extracts the access information (URL, authentication credentials) and embeds it in a code image. Users can then scan this code with their own devices that have network connectivity, separating the display function from the network connection requirement and improving reliability for offline scenarios.
3Adaptability or versatility
If the image processing device generates and displays a code image instead of web content, then web content can be accessed on different devices without network connection, but the direct web content display functionality is lost
Solution Approach 1:
The patent applies universality by making the code image a universal interface that works across multiple devices and platforms. The generated code image can be scanned by smartphones, tablets, computers, or other devices with camera and QR code scanning capabilities. This universal approach allows the same code image to serve different users on different devices, achieving cross-device compatibility while maintaining ease of operation through the familiar QR code scanning interaction.

AI summary
An image processing device includes a display unit and is capable of displaying web content provided via a web browser. The image processing device includes a first display controller displays web content acquired from a content server by using access information for acquiring the web content from the content server based on an instruction to display the web content, a QR generation unit generates a code image including the access information for acquiring the web content from the content server; and a second display controller displays the code image on the display unit. The QR generation unit generates a code image and the second display controller displays the code image on the display unit in a case where the first display controller is not able to display the web content.
