Image Processing Apparatus Single Scan Fax Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fax transmission systems require multiple operations to change resolution and preview print, leading to increased user inconvenience and potential degradation of image quality during transmission.
Innovation Solution
An image processing apparatus with a reading unit, setting unit, generation unit, printing unit, receiving unit, and transmission unit that allows users to set and transmit image data at a selected resolution, enabling single scan operation for preview printing and fax transmission while ensuring compatibility with the destination's print capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the resolution for fax transmission is increased, then the image quality and readability of detailed characters are improved, but the transmission time and telephone charge increase
Solution Approach 1:
The system performs preview printing at fax transmission resolution before actual transmission, allowing users to verify image quality and readability in advance. This preliminary action enables users to confirm that the selected resolution is sufficient without needing to perform additional reading operations, thus avoiding unnecessary transmission time delays while ensuring image quality requirements are met.
2Loss of time
If the resolution for fax transmission is decreased, then the transmission time and telephone charge are reduced, but the readability of detailed characters and complicated image data deteriorates
Solution Approach 1:
The system generates and prints preview images at the selected fax transmission resolution before actual transmission. This allows users to visually assess whether the reduced resolution maintains sufficient readability for their needs, enabling informed decisions about resolution selection that balance transmission efficiency with image quality requirements.
3Measurement precision
If a reading operation is performed again to change resolution and perform preview printing, then the preview accuracy is improved, but the operation time and user convenience deteriorate
Solution Approach 1:
The system performs the reading operation once at high resolution and then generates preview images at various fax transmission resolutions from the already-read high-resolution image data. This eliminates the need to perform reading operations multiple times, maintaining preview accuracy while significantly improving user convenience by reducing operation time and steps.
Solution Approach 2:
The system separates the reading function from the resolution conversion function. The reading unit reads the original once at high resolution, and then the image processing unit segments the task of generating preview images at different resolutions from the already-acquired high-resolution data, avoiding redundant reading operations and improving overall efficiency.
Data Source
AI summary
An original is read, image data is generated, image data of a set transmission resolution is generated based on the generated image data, printing is performed based on the generated image data, a transmission instruction is accepted, and image data of a set transmission resolution is transmitted in accordance with the accepted transmission instruction.
