Image Communication Apparatus Print Quality Verification Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image communication apparatuses cannot verify the quality of image data printed by the receiving side apparatus, as they only provide receipt acknowledgment but not quality assessment.
Innovation Solution
An image communication apparatus with a scanning unit, difference extracting unit, and control unit that compares scanned image data with stored data to determine if the printed image meets predetermined quality conditions, transmitting a message to the transmission source based on the comparison.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only receipt acknowledgment notifying function is implemented, then device complexity is reduced, but the transmitter cannot check the quality of the image data printed by the receiving side apparatus
Solution Approach 1:
The patent implements a feedback mechanism where the receiving side apparatus scans the printed image, compares it with the transmitted image data, and notifies the transmitter of the results. This allows the transmitter to verify image quality while maintaining a relatively simple overall structure by utilizing the existing scanning and processing capabilities already present in the receiving side apparatus.
Solution Approach 2:
The receiving side apparatus performs self-verification by scanning its own printed output and comparing it with the received image data. This self-service approach eliminates the need for separate verification equipment, allowing the system to monitor and report on its own performance without adding external complexity.
2Measurement precision
If difference extraction and quality assessment functions are added, then image quality verification capability is improved, but device complexity increases
Solution Approach 1:
The patent makes the processing unit on the receiving side apparatus multi-functional by enabling it to perform not only image reception and printing but also image scanning, difference extraction, quality assessment, and notification functions. This universal approach allows a single device to handle multiple tasks, improving measurement precision without proportionally increasing complexity.
Solution Approach 2:
The system changes parameters such as scanning resolution, comparison thresholds, and evaluation criteria to achieve accurate image quality measurement. By adjusting these parameters, the system can perform precise quality assessment using existing hardware capabilities, avoiding the need for more complex dedicated measurement equipment.

AI summary
An image communication apparatus that includes an image-data receiving unit that receives image data, a storing unit that stores therein the image data received by the image-data receiving unit, and an output unit that outputs the image data stored in the storing unit, the image communication apparatus includes a scanning unit that scans the image data output by the output unit; a difference extracting unit that extracts a difference between the image data scanned by the scanning unit and the image data stored in the storing unit; a difference determining unit that determines whether the difference extracted by the difference extracting unit satisfies a predetermined condition based on condition information obtained together with the image data; and a control unit that controls so that a message is transmitted to a transmission source of the image data based on a result determined by the difference determining unit.
