Smart Zoom Algorithm for Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face frustration in zooming operations due to small visible differences when transitioning from fit-to-screen zoom ratios to next default zoom ratios, leading to slow and unnoticeable zooming experiences, especially when dealing with images too large for the device's display.
Innovation Solution
The electronic device employs a smart zoom algorithm that determines the difference between the fit-to-screen zoom ratio and the next default zoom ratio, setting a show zoom ratio based on this difference and the zooming direction, allowing for significant and noticeable zooming steps by skipping insignificant zoom ratios, thereby enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the device uses the next default zoom ratio after fit-to-screen zoom ratio, then the zooming operation is simple and fast, but the visible difference between zoomed images is very small and not noticeable
Solution Approach 1:
The patent changes the zoom ratio parameter dynamically based on the fit-to-screen zoom ratio. When the difference between fit-to-screen ratio and next default ratio is small, the system adjusts to use a larger zoom step that provides noticeable visual difference, thereby resolving the contradiction between fast simple zooming and visible zoom effect.
2Reliability
If the device waits for zooming to complete before showing the result, then the zoom quality is maintained, but the user experience becomes frustrating due to time delay
Solution Approach 1:
The patent introduces dynamic zoom ratio selection that adapts to the current zoom state. By calculating the difference between fit-to-screen ratio and default ratios, the system dynamically chooses the appropriate zoom step, providing noticeable results faster while maintaining quality through intelligent parameter adjustment.
3Ease of manufacture
If the device uses easy default zoom ratios (2n:1, 1:2n), then the processing capability is improved and quality is maintained, but the zooming effect is not noticeable when starting from fit-to-screen ratio
Solution Approach 1:
The system changes the zoom ratio parameter based on the relationship between fit-to-screen ratio and default ratios. When the natural progression to next default ratio provides insufficient visual change, the system adjusts to a larger zoom step that maintains processing efficiency while delivering noticeable user-perceived zoom effect.

AI summary
An electronic equipment is disclosed, which includesscreen means for showing an image by using the set show zoom ratio andprocessor means for performing zooming of the image in a selected zooming direction in order to show the image on the screen means, in which zooming operation a such of fit-to-screen zoom ratio is arranged to be determined by using of which the image is to be fitted on the screen means and in which part of the possible show zoom ratios are arranged to form default zoom ratios changing in a set manner in order to deal out successive zooming operations in the selected zooming direction. By the processor means is arranged to be determined the difference between the fit-to-screen zoom ratio and the next default zoom ratio in the selected zooming direction and based on the difference and the zooming direction is arranged to be set the said show zoom ratio.
