Image Forming Device Code Image Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming devices fail to read code images previously embedded in original document images when additional code images are added during printing, leading to incomplete or incorrect decoding.
Innovation Solution
An image forming device and method that includes a control portion to manage user authentication, information extraction, and code image processing, allowing for the detection and decoding of embedded code images, and the addition of new code images to prevent interference and ensure readability of the original embedded code.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a code image is added to an image document during printing, then the document can be identified or tracked, but the previously embedded code image in the original document cannot be read
Solution Approach 1:
The patent segments the code image addition process into distinct phases: first detecting and preserving the original code image location and content, then adding the new code image in a separate operation. This segmentation allows both code images to coexist without interference, resolving the contradiction between adding new code images and maintaining readability of original code images.
Solution Approach 2:
The patent applies preliminary action by detecting and recording the position and content of the originally embedded code image before adding the new code image. This preliminary detection and preservation ensures that the original code image remains readable even after the new code image is added, thus resolving the reliability issue.
2Reliability
If code image detection and preservation measures are implemented, then original code images can be read, but the device complexity increases
Solution Approach 1:
The patent implements self-service by enabling the printing device to automatically detect, analyze, and preserve original code images during the printing process. The device performs self-diagnosis of code image presence and automatically adjusts its processing to maintain readability, reducing the need for external intervention or complex manual configuration while ensuring reliability.

AI summary
Another code image is added so that a code image previously embedded in an original document image can be read. An image forming device (3001) includes: a generation means (S111) configured to use, when a second code image is combined with the original document image including a first code image, a result of decoding of the first code image to generate a third code image; and means (S112) configured to combine the second code image with the original document image and combine the third code image on the second code image.
