Image Repeat Layout with Sheet Size and Repetition Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in determining the appropriate sheet size for image repeat processing, leading to cropped or reduced repeat target images when trying to print multiple copies, as existing technologies either crop or reduce the image size to fit the selected sheet.
Innovation Solution
An image processing apparatus that performs image analysis to detect and correct the document area, calculates the number of repetitions for various sheet sizes, and displays a list of possible sheet sizes for the user to select, allowing the image to be repeatedly laid out and printed without cropping or reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the user specifies the number of repetitions and selects a sheet size in advance, then the image can be printed multiple times, but the repeat target images must be cropped or reduced in size to fit the sheet
Solution Approach 1:
The system performs preliminary calculation of the number of repetitions for each candidate sheet size before the user makes a selection. This allows the user to see the expected output for each sheet size option and make an informed decision without needing to understand complex layout calculations, thus preventing image cropping or reduction while maximizing productivity
Solution Approach 2:
The system changes the parameter of sheet size to offer multiple candidate options (e.g., A4, A3, B4) and calculates the corresponding number of repetitions for each. By varying this parameter, the user can select the appropriate sheet size that accommodates the desired number of repetitions without image quality degradation
2Area of stationary object
If the repeat target images are cropped or reduced in size to fit the selected sheet, then the sheet size constraint is satisfied, but the user cannot obtain the desired print product with full-size images
Solution Approach 1:
The system automatically calculates and displays the number of repetitions for each candidate sheet size, enabling the user to make an informed selection without manual calculation or trial-and-error. This self-service approach ensures the user can obtain full-size repeated images on the appropriate sheet size, satisfying both technical constraints and user needs
3Manufacturing precision
If the user needs to print multiple copies without cropping or reducing the image size, then the image quality is maintained, but the user has difficulty finding the appropriate sheet size
Solution Approach 1:
The system provides feedback by displaying the calculated number of repetitions for each candidate sheet size. This feedback mechanism guides the user to select the appropriate sheet size that will produce the desired number of full-size repeated images, simplifying what would otherwise be a complex selection process

AI summary
A tilt-corrected document image is obtained by performing image analysis processing on a scan image to detect a document area and performing extraction and tilt correction of a document image based on the detected document area. A repeat target area is set based on the obtained tilt-corrected document image. The number of repetitions in repeatedly laying out the repeat target area for each of a plurality of candidate sheet sizes is calculated, and a list screen showing the calculated numbers of repetitions for the respective plurality of candidate sheet sizes is displayed. A repeat layout-processed output image is generated by repeatedly laying out an image of the repeat target area within a sheet size specified by a user, and print processing is made executable.
