Facsimile Image Size Conversion for Automatic Paper Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing apparatuses fail to adjust image sizes received via facsimile communication, leading to incorrect paper selection during printing, as they do not convert image data to suitable print paper sizes, resulting in A4-size documents being printed on Legal size paper, requiring users to manually reselect paper.
Innovation Solution
An image processing apparatus with a reception unit for receiving facsimile data, a conversion unit that adjusts the image data to a fixed print paper size, and a storage unit to store the converted data, allowing for automatic selection of the appropriate recording paper based on the image size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image data is stored without size adjustment, then the original image quality and dimensions are preserved, but the paper size selection during printing becomes incorrect (e.g., A4 documents printed on Legal size paper)
Solution Approach 1:
The patent applies preliminary action by adjusting the image size during the reception and storage phase, before the printing phase occurs. The conversion unit automatically converts received facsimile image data to a predetermined paper size (e.g., A4) and stores it with corrected dimension information. This preliminary size adjustment ensures that when printing occurs, the system correctly identifies the paper size without requiring manual user intervention to reselect paper dimensions.
2Extent of automation
If image data is converted to fixed print paper size, then automatic paper size selection is enabled, but the original image dimensions are changed
Solution Approach 1:
The patent applies parameter changes by modifying the image dimension parameters during storage. The conversion unit changes the image data from its original facsimile dimensions (e.g., 215mm x 297mm) to predetermined paper size parameters (e.g., A4 size). This parameter transformation enables automatic paper size selection during printing while accepting that the physical dimensions are adjusted to match standard paper formats.
3Productivity
If no size conversion is performed on received image data, then processing time is minimized, but printing requires manual reselection of recording paper
Solution Approach 1:
The patent applies preliminary action by performing size conversion during the reception and storage phase rather than during printing. The conversion unit automatically adjusts image dimensions to predetermined paper sizes and stores the converted data with corrected dimension information. This eliminates the need for manual paper reselection during printing, saving user time while adding minimal processing time during the initial reception phase.

AI summary
An image processing apparatus includes a reception unit, a conversion unit, and a storage unit. The reception unit receives image data by facsimile communication. The conversion unit converts the image data received by the reception unit into image data having a print paper size of a fixed size. The storage unit stores, in a file, the image data converted by the conversion unit.
