Network Scanner Selective Page Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network scanners face high communication loads and increased communication time due to repetitive transmission of large image data when users change reading conditions or transmit data to multiple terminals, which is inefficient and wastes memory.
Innovation Solution
A network scanner with a transmission part specifying mechanism that allows users to transmit only representative image data, selectively transmit or delete data based on user requests, and set storage limits to minimize network load and memory usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all image data are transmitted to terminals for user confirmation, then the user can confirm detailed reading conditions, but the network communication load increases and communication time extends
Solution Approach 1:
The patent divides the complete image data into multiple pages and allows selective transmission of only necessary pages. The transmission part specifying means enables users to specify which pages need to be transmitted, segmenting the large image data into manageable portions that reduce network load while maintaining the ability to confirm reading conditions.
Solution Approach 2:
Instead of transmitting all image data, the patent implements partial transmission by sending only the specified pages that users need for confirmation. This partial action approach reduces communication load while still providing sufficient information for users to verify reading conditions and make necessary adjustments.
2Adaptability or versatility
If image data are transmitted repeatedly when reading conditions change, then users can confirm updated conditions, but communication time increases and network load increases
Solution Approach 1:
The patent stores scanned image data in a predetermined memory section before transmission. When users need to change reading conditions or transmit data, the system can quickly access the pre-stored data and transmit only the necessary parts, eliminating the need to re-scan and re-transmit all data, thus reducing communication time while maintaining adaptability.
Solution Approach 2:
The transmission part specifying means dynamically determines which pages need to be transmitted based on user requests and reading condition changes. This dynamic selection allows the system to adapt to varying user needs and transmit only the necessary portions of data, reducing communication time compared to transmitting all data repeatedly.
3Loss of energy
If thumbnail transmission is used to reduce communication load, then network load decreases, but users cannot confirm detailed reading conditions and must obtain complete data again
Solution Approach 1:
The patent segments the complete image data into individual pages and allows users to specify which pages need to be transmitted. This segmentation enables the system to transmit only necessary pages rather than all data or just thumbnails, providing users with detailed reading condition information for confirmed pages while reducing overall communication load.
Solution Approach 2:
The patent creates a copy of the complete image data in the memory section and allows selective transmission of pages from this copy. This copying approach enables users to access detailed reading condition information for specific pages without transmitting the entire data set, balancing information accuracy with communication efficiency.
4Measurement precision
If complete image data are stored in memory for user confirmation, then users can verify reading conditions, but memory usage increases
Solution Approach 1:
The patent segments the complete image data into individual pages stored in memory. The transmission part specifying means then selects only the necessary pages for transmission, allowing the system to maintain accurate reading condition information in memory while reducing the amount of data that needs to be transmitted and processed.
Solution Approach 2:
Instead of transmitting all stored image data, the patent implements partial transmission by sending only the specified pages that users need for confirmation. This partial action approach reduces communication load while maintaining the ability to verify reading conditions, effectively managing memory usage by not unnecessarily transmitting all data.

AI summary
A network scanner for transmitting image data as read from a document, which has been stored in a predetermined memory includes: a transmission part specifying means for specifying a part of the image data to be transmitted to said terminal(s); and specified data transmission means for transmitting the part of the image data as specified by the transmission part specifying means to the terminal(s). According to the foregoing structure, the load on communicating can be significantly reduced.
