Print Preview Layout With Actual-Size View and Whole-Image Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The disparity between pixel density of display devices and printing resolution makes it difficult for users to accurately gauge the size of a print result, especially when using smartphones with smaller screens, necessitating multiple print trials for size adjustments.
Innovation Solution
A mechanism that displays an actual-size image preview superimposed with frame information, allowing users to visualize the entire print result and adjust sizes intuitively before printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an actual-size image is displayed on a display device to confirm print result size, then the user can see the print result in its actual size, but only a partial area is displayed on small screens like smartphones making it difficult to grasp the whole image
Solution Approach 1:
The patent divides the image display into two segments: an actual-size preview area showing the print result at its true dimensions, and a mini map area showing a scaled-down version of the entire image. This segmentation allows users to view the actual-size portion for accurate size confirmation while the mini map provides context about the entire image structure, resolving the contradiction between displaying actual size and grasping the whole image.
Solution Approach 2:
The patent adds a dimensional solution by displaying the mini map as a separate visual dimension alongside the actual-size preview. The mini map acts as a complementary view that provides overview information about the entire image, enabling users to grasp the whole image structure while maintaining accurate size perception of the actual-size portion.
2Measurement precision
If the display device screen size is smaller than the print sheet size, then the actual-size image cannot be fully displayed, but the user still needs to confirm the entire print result
Solution Approach 1:
The patent segments the display area into an actual-size preview area that shows the print result at its true dimensions for accurate size confirmation, and a mini map area that displays a scaled-down version of the entire image. This segmentation allows the actual-size portion to be displayed accurately while the mini map provides complete image context, resolving the contradiction between limited display area and need to confirm entire print result.
Solution Approach 2:
The patent creates a copy of the entire image in the form of a mini map that is scaled down to fit within the limited display area. This mini map copy allows users to grasp the overall image structure and confirm the entire print result context, complementing the actual-size preview and enabling complete verification within a smaller display area.
3Manufacturing precision
If multiple print trials are performed for size adjustment, then the user can achieve precise size fitting, but the time and effort required increases significantly
Solution Approach 1:
The patent creates a visual copy of the print result in actual size on the display device, allowing users to confirm size accuracy before physical printing. The actual-size preview area displays the print result as it will appear on the printed sheet, enabling users to make precise size adjustments by simply modifying the display settings rather than performing multiple physical printing trials, thus reducing time and effort while maintaining precision.
Solution Approach 2:
The patent performs the size confirmation action in advance by displaying the actual-size preview before physical printing occurs. Users can verify the size accuracy and make adjustments on the display device beforehand, eliminating the need for multiple iterative printing trials and achieving precise size fitting with a single print operation after the display confirmation.

AI summary
A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method of causing a printing apparatus to execute printing. The program causes an apparatus in which the program has been installed to display an actual-size image for confirming a print result in its actual size, before printing, and causes the apparatus to display a whole image for confirming a whole print result in a state superimposed on the actual-size image, before printing. In the whole image, frame information indicating an area displayed by the actual-size image is included.
