Printer Driver UI Image Cropping Preserves Main Object
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image size adjustment methods for printer driver preview displays can result in reduced legibility, removal of image portions, or excessive modification, leading to user misinterpretation of print settings.
Innovation Solution
A method for adjusting image size and aspect ratio on a printer driver user interface screen to ensure the main object is not removed, undergoes unnecessary reduction, or excessive modification, by cropping or resizing the image based on the output paper size, ensuring optimal display without margins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If simple cropping method is used to adjust image size, then the image fits the output region, but portions of the main object are removed reducing legibility
Solution Approach 1:
The patent performs enlargement processing of the image before cropping to ensure that the main object is fully preserved. By enlarging the image first, the system creates a larger working copy where the main object's distribution region is expanded, allowing subsequent cropping to fit the output region while maintaining complete visibility of the main object.
Solution Approach 2:
The patent applies different processing operations to different regions of the image based on the main object's distribution. The system identifies the main object's location and applies enlargement processing specifically to ensure the main object region is adequately preserved, while other regions are adjusted to fit the output constraints.
2Area of stationary object
If combination of cropping and enlargement/reduction is used, then the image fits the output region, but the original image undergoes excessive modification
Solution Approach 1:
The patent dynamically selects the appropriate image processing method based on the relationship between the image size and output region size. The system evaluates whether to apply only cropping, only enlargement, only reduction, or a combination of these operations, adjusting the processing strategy in real-time based on the specific dimensions and main object distribution.
3Loss of information
If enlargement processing is performed before cropping, then the main object is preserved, but the processing time increases
Solution Approach 1:
The patent performs enlargement processing of the image before cropping to ensure that the main object is fully preserved. By enlarging the image first, the system creates a larger working copy where the main object's distribution region is expanded, allowing subsequent cropping to fit the output region while maintaining complete visibility of the main object.

AI summary
A UI driver determines an output region corresponding to an output paper size in a display region of the printer driver UI, and if a length of at least one side of the output region is longer than a corresponding side of an original image, performs cropping of the original image such that a removed portion of a distribution region of a main object in the original image is at the minimum after enlarging the original image, and if a length of each side of the output region is shorter than or equal to a corresponding side of the original image and not longer than a corresponding side of the distribution region of the main object, performs cropping of the original image such that a removed portion of the distribution region of the main object is at the minimum after reducing the original image.
