Print Region Editing for Aspect-Ratio Image Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When printing images from smartphones, the mismatch between the image aspect ratio and the aspect ratio of standard print paper often results in either partial image cutting or the formation of white blanks, causing inconvenience to users.
Innovation Solution
A print region editing device and method that dynamically configures a print region rectangle or square based on the aspect ratios of both the guideline portion and the image, ensuring that the image's vertices align with the print region's vertices, thereby allowing for enlargement or maintenance of the image to fit the print region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the image is printed using print paper-full option to fill the print paper, then the print paper utilization is improved, but the original image is partially cut off
Solution Approach 1:
The patent implements dynamic aspect ratio adjustment by detecting the user's gesture state (dragging, pinching, or tapping) and automatically switching between different print region configuration modes. This dynamic response allows the system to adapt the print region boundaries in real-time based on user intent, ensuring both full paper utilization and complete image representation without manual intervention.
Solution Approach 2:
The system changes the print region configuration parameters (boundaries, aspect ratio, positioning) based on the detected gesture type. When a tapping gesture is detected, the system switches to a mode that prioritizes complete image display, adjusting the print region parameters to accommodate the entire image while minimizing white blanks, thereby resolving the contradiction between paper utilization and image integrity.
2Manufacturing precision
If the image pull option is used to print the entire original image, then the image integrity is improved, but a white blank is formed according to the ratio in the print option
Solution Approach 1:
The system dynamically adjusts the print region configuration based on the detected gesture state. When dragging or pinching gestures are detected, the system switches to a mode that prioritizes paper utilization, automatically adjusting the print region boundaries to fill the print paper while maintaining complete image representation, thereby eliminating white blanks and improving paper utilization.
Solution Approach 2:
The system changes the print region parameters (size, position, aspect ratio) based on the detected gesture type. For dragging and pinching gestures, the system adjusts parameters to maximize paper coverage while ensuring the entire image is included, thus resolving the contradiction between image integrity and print paper utilization.
3Adaptability or versatility
If the aspect ratio of the image does not match the aspect ratio of the print paper, then the printing flexibility is improved, but either partial image cutting or white blanks are formed
Solution Approach 1:
The patent segments the print region into multiple configurable zones with different aspect ratios and boundary definitions. By providing multiple print region configurations that can be selectively activated based on the detected gesture, the system accommodates various image aspect ratios without causing cutting or white blanks, thus maintaining both printing flexibility and print quality.
Solution Approach 2:
The system implements a universal print region configuration mechanism that handles multiple image aspect ratios and printing scenarios through a single gesture-based interface. The print region can dynamically adapt to different aspect ratios by switching between predefined configurations, making the system versatile while maintaining high print quality across all scenarios.

AI summary
Disclosed are a print region editing device and a method thereof. When an image is released during enlargement, reduction, or movement within a preset guideline portion, a print region rectangle or print region square of a longer-side length and a shorter-side length is configured according to a long-short ratio of the guide line portion and a long-short ratio of the corresponding image, and the corresponding image is enlarged or maintained so that four vertices of the corresponding image match four vertices of the configured print region rectangle or print region square, thereby freely changing a paper-full format and an image-full format depending on the enlargement or reduction of the image.
