Output Setting Device Multi-Touch Scale Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses limit the number of settable magnifications for printing images with aspect ratios different from standard paper sizes, often requiring excessive reduction or insufficient enlargement to fit images onto available paper sizes.
Innovation Solution
An output setting device with a touch-sensitive panel capable of multi-touch gestures sets a scale ratio that maintains the aspect ratio of images unchanged, allowing at least one dimension to match standard paper sizes, enabling more flexible image sizing options beyond the limitations of standard paper sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the image is scaled to fit standard paper sizes, then the image can be printed on available paper, but the aspect ratio may be distorted or the image must be excessively reduced/enlarged
Solution Approach 1:
The patent changes the parameter of scale ratio selection from discrete standard-size-based options to continuous options based on aspect ratio matching. The setting portion calculates scale ratios that maintain the original aspect ratio while fitting within paper boundaries, allowing precise control over image scaling without being constrained to predetermined magnifications tied to standard paper sizes.
2Device complexity
If the number of settable magnifications is limited to standard paper sizes, then the device complexity is reduced, but the adaptability to different image aspect ratios is limited
Solution Approach 1:
The patent introduces dynamic calculation of scale ratios based on the relationship between image aspect ratio and paper size. Instead of using fixed magnification values, the system dynamically determines appropriate scale ratios by comparing the image dimensions with available paper sizes, allowing the magnification to adapt automatically to different image and paper combinations while maintaining aspect ratio.
3Ease of operation
If pinch-in or pinch-out gestures are used to adjust image size, then the ease of operation is improved, but the precision of achieving exact fit to paper size is reduced
Solution Approach 1:
The patent implements feedback by calculating and displaying the appropriate scale ratio based on the detected gesture direction (pinch-in or pinch-out) and the relationship between image aspect ratio and paper size. The system provides precise scale ratio adjustments in response to gestures, ensuring that the image fits exactly within paper boundaries while maintaining aspect ratio, thereby combining gesture-based ease of operation with precise measurement.

AI summary
An output setting device for setting a scale ratio for image size change when an image is reduced or enlarged to be placed in an output page is provided. The device includes a touch-sensitive panel capable of detecting a multi-touch; and a setting portion setting, when a multi-touch gesture for giving a command to change the image size is made on the touch-sensitive panel, as the scale ratio for image size change, a scale ratio closest to a present scale ratio from among scale ratios available when the image is reduced or enlarged in accordance with the multi-touch gesture in such a manner that at least one of a vertical dimension and a horizontal dimension of the image size is made equal to any one of a vertical dimension and a horizontal dimension of any one of standard sizes with an aspect ratio of the image remaining unchanged.
