Information Code Integrating Image Region for Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information codes, such as two-dimensional codes, primarily utilize cell arrangements for data storage and do not effectively utilize images within the code region for analysis or application beyond presentation, limiting their usability and functionality.
Innovation Solution
An information code system that integrates an image region within the code area, allowing both data recorded by cells and images to be interpreted and utilized by applications, with a reader capable of processing and recognizing images in the image region for authentication and other purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only cell arrangements are used for data storage in information codes, then the data storage function is reliable, but the usability and functionality are limited
Solution Approach 1:
The patent merges the data storage function (cell arrangements) with the presentation function (image region) into a single integrated code structure. The image region is embedded within the code area alongside the data recording region, allowing both functions to coexist in one information code without requiring separate components.
Solution Approach 2:
The information code is designed to serve multiple functions simultaneously: it stores data through cell arrangements and provides visual presentation through the image region. The reader device is also made universal by capable of both reading cell data and processing images, enabling the system to handle diverse application requirements from a single code structure.
2Adaptability or versatility
If design regions are used for presentation only, then the visual appeal is improved, but the functionality for analysis and reading is not enhanced
Solution Approach 1:
The patent combines the design region with the image region to create a unified structure that serves both presentation and functional purposes. The image region can contain various types of content including designs, logos, or authentication images, all of which can be processed by the reader device for enhanced functionality.
3Adaptability or versatility
If images are added to the code region, then the application flexibility is improved, but the reading and processing complexity increases
Solution Approach 1:
The code area is segmented into distinct functional regions: the data recording region for storing information through cell arrangements and the image region for containing images. This segmentation allows the reader device to process different regions using appropriate methods, reducing overall processing complexity while maintaining application flexibility.

AI summary
There are provided a two-dimensional information code (100), a producing apparatus (2) which produces this information code, an information code reader (10) which reads the information code, and a system which uses the information code. The information code is provided with various regions arranged thereon. The regions include specification pattern regions including position detection patterns (104), a data recording region, error-correction-code recording regions, and an image region (121) in which an image is formed. The image in the image region is different from cell images. The reader (10) includes an image processing section (40) which recognizes the image formed in the image region in a captured image (a code image) of the information code (100), by a method different from a data interpretation process performed by a data-recording region reading section (40).
