Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses face challenges in efficiently cropping and ordering multiple document images read simultaneously, leading to inefficient output processing and user inconvenience.
Innovation Solution
The apparatus includes an image reader unit and a control unit that detect distances between document images and reference sides, sorting and ordering them based on these distances to optimize cropping and output, allowing for customizable output ordering and suppression of unnecessary data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple documents are read simultaneously and cropped using conventional methods, then the quantity of image data processed increases, but the output ordering becomes inefficient and difficult to control
Solution Approach 1:
The control unit performs preliminary detection of document positions by calculating distances from reference sides before cropping. This preliminary positioning action enables subsequent efficient sorting and ordering of cropped images based on their detected positions, resolving the contradiction between processing multiple documents and maintaining controllable output ordering
Solution Approach 2:
The patent replaces manual ordering mechanisms with automated distance-based detection and sorting. By substituting mechanical/manual positioning with computational distance measurement from reference sides, the system achieves both high processing efficiency and precise output ordering control
2Ease of manufacture
If conventional cropping methods are used for multiple documents, then the cropping process is simple, but unnecessary data may be output and ordering cannot be customized
Solution Approach 1:
The control unit extracts and processes only the necessary image data by detecting document positions through distance measurement from reference sides. This extraction approach enables the system to identify and output only relevant document images in the correct order, preventing unnecessary data output while maintaining simple cropping operations
Solution Approach 2:
The system uses feedback from distance detection to control the cropping and ordering process. By continuously monitoring the detected positions of documents relative to reference sides, the control unit adjusts the cropping parameters and output ordering to ensure only necessary data is processed and output in the correct sequence
Data Source
AI summary
An image forming apparatus includes an image reader unit and a control unit. The image reader unit generates read data. The control unit generates output data of image data cropped from the read data. When cropping a plurality of image data, the control unit sets one side of the read data to a first reference side and sets another side perpendicular to the first reference side to a second reference side, and for each of the plurality of image data, the control unit detects a first distance between the first reference side and the image data in a direction parallel to the second reference side, and a second distance between the second reference side and the image data in a direction parallel to the first reference side, and sets an output order of the plurality of image data based on the first distances and the second distances.
