Autonomous Document Reading Controller for Image Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems face inefficiencies in reading and transferring document images, particularly in scenarios where documents are read independently of commands from the host apparatus, leading to delays and resource mismanagement.
Innovation Solution
An image processing apparatus with a document reading section, a transfer section, and controllers that autonomously read and transfer document images based on page counts, allowing subsequent pages to be read independently of host commands, optimizing the use of buffer capacity and reducing processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the document reading section reads subsequent pages independently of host commands, then productivity is improved by reducing waiting time, but device complexity increases due to autonomous control mechanisms
Solution Approach 1:
The reading controller performs preliminary actions by autonomously reading subsequent pages after the first sheet without waiting for host commands. This allows the document reading section to prepare and transfer multiple pages in advance, improving productivity by eliminating waiting time while the controller manages the complexity through automated page count tracking
Solution Approach 2:
The image processing apparatus serves itself by having the reading controller automatically determine when to read and transfer pages based on the number of pages read versus transferred. This self-service mechanism improves productivity by eliminating the need for continuous host intervention while the controller's autonomous logic manages the system complexity
2Reliability
If the system transfers images after each sheet is read, then reliability is improved by ensuring complete transfer, but loss of time increases due to frequent transfer operations
Solution Approach 1:
The system maintains continuity by reading subsequent pages continuously without interruption and transferring them in sequence based on page count comparison. This continuous operation ensures all images are reliably transferred while minimizing idle time between read and transfer operations, as the controller continuously monitors and coordinates the process
Solution Approach 2:
The reading controller uses feedback by comparing the number of pages read versus the number of pages transferred. This feedback mechanism ensures reliability by tracking the transfer status and adjusting reading operations accordingly, while also optimizing time by preventing unnecessary waiting or redundant operations

AI summary
An image processing apparatus includes a document reading section, a reading controller, an image transfer section, and a transfer controller. The document reading section reads documents. The reading controller controls the document reading section so as to read document images subsequent to a first sheet independently of a command from a host apparatus. The image transfer section transfers the document images which are read by the document reading section. The transfer controller controls the image transfer section based on the number of pages of the documents, which are read by the document reading section, and the number of pages of the document images, which are transferred by the image transfer section, in a case where the document images are transferred by the image transfer section whenever the document reading section reads one sheet of document.
