Image Processing Apparatus Crop Mark Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies do not effectively address how to arrange images with crop marks when the image arrangement is automatically set by the application program, leading to crop marks overlapping non-printable areas and reducing user convenience.
Innovation Solution
A control method for an image processing apparatus that includes displaying a printable and non-printable area, allowing for the automatic adjustment of image and crop mark positions within the display area to ensure they fall within the printable area, thereby preventing overlap with non-printable regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the application program automatically sets image arrangement, then the operation process is simplified and productivity is improved, but crop marks may overlap with non-printable areas causing printing errors
Solution Approach 1:
The system performs preliminary detection of crop mark positions and printable area boundaries before finalizing the automatic arrangement. By checking in advance whether crop marks would overlap non-printable areas, the system can adjust image positions proactively to prevent printing errors, thus maintaining both automation and reliability
Solution Approach 2:
The system implements a feedback mechanism where the detection unit continuously monitors crop mark positions relative to printable areas, and the control unit adjusts arrangements based on this feedback. This closed-loop control ensures that automatic arrangement maintains printing accuracy by correcting positions when crop marks approach non-printable zones
2Manufacturing precision
If crop marks are set for images displayed by the application program, then the printing precision is improved, but the device complexity increases due to additional detection and control mechanisms
Solution Approach 1:
The detection unit serves multiple functions: it detects both image positions and crop mark positions, and also determines printable area boundaries. By making this single unit multi-functional, the system achieves precise crop mark positioning without proportionally increasing overall system complexity
Solution Approach 2:
The patent combines the detection of crop marks and printable areas into a unified detection process, and merges the control logic for image arrangement with crop mark positioning. This consolidation reduces the number of separate components needed, achieving precise positioning while limiting complexity growth
3Reliability
If the printable area is enlarged to accommodate crop marks, then the crop marks can be printed without overlapping non-printable areas, but the area available for actual image content is reduced
Solution Approach 1:
The system dynamically adjusts image positions rather than statically enlarging the printable area. By moving images flexibly within the existing printable boundaries, the system ensures crop marks fall within printable zones while maximizing the utilization of available image display space
Solution Approach 2:
The control unit changes the position parameters of images and crop marks based on detected conditions. Rather than altering the printable area size, the system modifies coordinates and dimensions of individual elements to achieve proper positioning, preserving both crop mark printability and image display area

AI summary
A control method for an image processing apparatus includes displaying a display area that includes a printable area corresponding to an area to be printed on a recording medium and a non-printable area corresponding to an area not to be printed and in which at least one image that is a printing target is to be arranged, display a setting area, other than the display area, for accepting an operation for automatically changing, within the display area, a position of the at least one image arranged in the display area, and, upon accepting the operation on the setting area, automatically changing a position of a predetermined image arranged in an uppermost portion of the display area and a position of at least part of a crop mark, the part being set above the predetermined image, such that the predetermined image and the part fall within the printable area.
