Continuous Zoom Control via Dual-Point Gesture Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for image processing in medical and biological fields require multiple discontinuous operations to adjust zoom magnification, significantly reducing efficiency when handling numerous images, particularly in fields like medicine where speed is crucial.
Innovation Solution
An information processing apparatus and method that allows zooming of images by designating two points on an image, determining the zoom direction and magnification based on their positions, and generating a zoomed image with a candidate area at the center, utilizing a hierarchical structure of image data for efficient access and display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple discontinuous operations are required to adjust zoom magnification, then the system can perform precise image manipulation, but the operation efficiency deteriorates significantly
Solution Approach 1:
The patent combines the center point designation and zoom magnification setting into a single continuous operation. By detecting a drag gesture from a first position to a second position, the system simultaneously determines both the zoom center and the zoom magnification based on the distance between positions, eliminating the need for separate discrete operations.
Solution Approach 2:
The system performs preliminary calculation of zoom parameters during the drag operation itself. The zoom magnification is determined based on the distance between the first and second positions detected during the continuous gesture, allowing the zoom operation to be executed immediately without requiring additional separate setting steps.
2Measurement precision
If separate operations are needed to designate center point and zoom magnification, then the system maintains operational precision, but the number of operations increases
Solution Approach 1:
The patent merges two separate operations (designating center point and setting zoom magnification) into a single continuous drag gesture. The start position of the drag serves as the zoom center, while the distance traveled during the drag determines the zoom magnification, thereby reducing operational complexity while preserving precision.
Solution Approach 2:
The patent introduces a spatial dimension to the zoom operation by using the distance of a continuous gesture to determine zoom magnification. Instead of separate numerical inputs, the system translates the physical distance of the drag gesture into the zoom level, adding a spatial component that combines both center designation and magnification setting in one action.
