Document Transmission Frame Size Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing apparatuses face challenges in transmitting image data without generating waiting times, especially when dealing with documents of irregular sizes, as they often require larger frame sizes that lead to inefficient data transmission and increased frame counts.
Innovation Solution
The apparatus employs a serial interface with limited frame sizes, using a transmission controller to determine document sizes and select smaller frame sizes for irregular documents, ensuring data transmission is completed before the start of the next document, thereby reducing the number of frames needed and minimizing waiting times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If larger frame sizes are used for transmitting image data of irregularly sized documents, then the transmission capacity per frame increases, but the number of frames required increases and waiting times occur between document transmissions
Solution Approach 1:
The patent applies dynamics by making the frame size adjustable rather than fixed. The transmission controller dynamically selects frame sizes based on the actual document size being transmitted. For irregularly sized documents, the system can switch between different frame size modes (first frame size and second frame size) to optimize transmission timing and ensure completion before the next document arrives, thereby eliminating waiting times while maintaining efficient transmission.
2Loss of time
If smaller frame sizes are selected for irregular documents, then the number of frames needed increases, but transmission can be completed before the next document starts
Solution Approach 1:
The patent implements parameter changes by varying the frame size parameter according to document characteristics. The transmission controller changes the frame size parameter dynamically - using a first frame size for certain documents and a second frame size for others - based on the timing requirements and document size. This parameter adaptation allows the system to meet transmission deadlines without requiring complex control mechanisms, as the frame size adjustment is the primary variable being modified.
3Reliability
If frame size is limited by serial interface specifications, then transmission protocol compatibility is improved, but flexibility in handling documents of various sizes is reduced
Solution Approach 1:
The patent achieves universality by designing a transmission controller that can handle multiple document size scenarios within the constraints of a fixed frame size system. The controller is configured to work with serial interfaces that have limited frame size options, yet it can adaptively manage transmissions for documents of various sizes by selecting appropriate frame sizes and adjusting transmission parameters. This multi-functional capability allows the same system to reliably transmit different document types while maintaining serial interface compatibility.

AI summary
An information processing apparatus for transmitting image data input by sequentially reading documents, with limiting an allowable frame size, includes: a transmission controller, wherein, in a case where the document has an irregular size, the transmission controller transmits the image data to a transmission destination in a preset frame of a first frame size until a rear edge of the document is detected, and if a portion, which is not transmitted, of the image data exists when the rear edge of the document is detected, transmits the portion to the transmission destination in a frame of a second frame size smaller than the first frame size so that the transmitting of the portion is finished before a start of transmission of image data corresponding to a next document.
