Scanner Sequential Image Data Group Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scanners face difficulties in generating and supplying files to external devices when the number of sheets is large due to insufficient memory space, leading to situations where files cannot be transmitted.
Innovation Solution
A scanner system that reads images from sheets, generates image data groups sequentially, and supplies them to an external device through a network, using joint information to combine multiple data groups into a single file, thereby overcoming memory limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all sheets are read and stored in the scanner memory, then a complete file can be generated and supplied to the external device, but the scanner memory space is insufficient when the number of sheets is large
Solution Approach 1:
The patent divides the complete file into multiple image data groups, each containing image data from a subset of sheets. Instead of storing all sheet images in scanner memory, the system processes and transmits them in segmented groups, with each group being self-contained and transmittable independently through the network.
Solution Approach 2:
The patent introduces joint information as an intermediary element that enables the external device to assemble multiple image data groups into a complete file. This joint information acts as a mediator between the segmented image data groups, allowing reconstruction of the original complete file without requiring the scanner to maintain all image data in memory simultaneously.
2Ease of manufacture
If image data from all sheets is stored in the scanner, then a single file can be generated, but the process becomes difficult and memory-intensive when the number of sheets is large
Solution Approach 1:
The patent segments the file generation process into multiple independent image data group operations. Each group is processed, formatted, and transmitted separately, eliminating the need to manage large amounts of image data in scanner memory simultaneously and simplifying the overall process.
Solution Approach 2:
The patent extracts the file assembly function from the scanner by providing joint information to the external device. This allows the scanner to focus on reading and transmitting image data groups, while the external device performs the file generation task, reducing the scanner's memory management complexity.
3Productivity
If the scanner processes all sheets sequentially before transmission, then complete image data is available, but the transmission cannot be completed when memory space is insufficient
Solution Approach 1:
The patent segments the image data into multiple transmittable groups that can be processed and transmitted sequentially through the network. Each image data group is complete in itself and can be transmitted independently, allowing continuous processing and transmission without being blocked by memory constraints.
Solution Approach 2:
The patent enables continuous reading, processing, and transmission of image data groups without interruption. By transmitting each completed group immediately through the network rather than waiting to accumulate all data, the system maintains continuous productive action throughout the scanning and transmission process.
Data Source
AI summary
A scanner connected to an external device through a network is provided. The scanner includes, a reading section that reads an image recorded on a sheet so as to generate image data, an image data group supply section that, in a case where a plurality of images recorded on a plurality of sheets are read by the reading section, sequentially generates an image data group every time a part of the plurality of sheets is read by the reading section, and sequentially supplies the generated image data group to the external device, a joint information generation section that generates joint information used to join two or more of the image data groups, the two or more of the image data groups representing the plurality of images; and a joint information supply section that supplies the joint information to the external device.
