Fax Transmission System for Reliable QR Code Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fax transmission systems often result in incomplete QR Codes being received, making it difficult for users to decode QR Codes when image data is faxed, due to variations in transmission resolution.
Innovation Solution
A transmission system comprising a first and second fax apparatus, where the first apparatus decodes QR Code information from image data and transmits it separately, and the second apparatus re-encodes and adds it back to the image data for printing, ensuring the QR Code is complete and decodable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image data including QR Code is transmitted through fax communication, then the QR Code can be transmitted to the receiving apparatus, but the QR Code may become incomplete due to transmission resolution limitations
Solution Approach 1:
The patent divides the transmission into two separate channels: one for image data and another for QR Code information. The acquisition unit extracts QR Code information from the image data, and the transmission unit sends this information separately through the fax communication, ensuring it arrives intact regardless of image resolution limitations.
Solution Approach 2:
The patent introduces an intermediary processing mechanism where the acquisition unit decodes QR Code information from the image data, and the generation unit re-encodes it. This intermediary process ensures the QR Code information is preserved and can be reconstructed accurately at the receiving end, overcoming the resolution limitations of direct fax transmission.
2Productivity
If the QR Code is decoded and replaced with reconstructed image data, then the transmission can be optimized, but the QR Code may become incomplete and undecodable
Solution Approach 1:
The acquisition unit extracts the QR Code information from the image data by decoding the QR Code. This extracted information is then transmitted separately through the fax communication, ensuring it is not lost or corrupted during the transmission process, while the image data can be optimized for transmission efficiency.
Solution Approach 2:
The patent discards the original QR Code from the image data stream during transmission, extracting its information separately. The generation unit then recovers and re-encodes this information, ensuring the QR Code is complete and decodable at the receiving end, while allowing the image data to be transmitted efficiently without the QR Code overhead.

AI summary
A transmission system includes a first fax apparatus, and a second fax apparatus, wherein the first fax apparatus includes a transmission unit that performs fax communication, and an acquisition unit that acquires information by decoding code information included in image data, wherein the transmission unit transmits the image data and the acquired information via the fax communication, and wherein the second fax apparatus includes a reception unit that performs the fax communication, a generation unit that generates code information by encoding the information received by the reception unit via the fax communication, an addition unit that adds the generated code information to the image data received by the reception unit, and a printing unit that prints an image on a sheet based on image data obtained by adding the generated code information to the received image data.
