Microscope Touch Panel Zoom Control via Center Point Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current microscope systems lack intuitive and efficient methods for adjusting zoom magnification and observation positions, relying on complex operations that can distract users from the sample observation.
Innovation Solution
A microscope system incorporating a touch panel for intuitive zoom control, where the zoom magnification is adjusted by setting a middle point between two contact positions on the panel, allowing for single-operation enlargement or reduction of the observation area without changing the desirable observation position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional operation controllers (joy stick or hand switch) are used to control zoom magnification, then the control method is well-established, but the operation becomes complex and distracts users from sample observation
Solution Approach 1:
The patent replaces traditional mechanical operation controllers (joy stick, hand switch) with a touch panel that detects contact positions through capacitive or resistive sensing. This substitution eliminates mechanical moving parts and simplifies the control interface to a flat touchscreen surface, making operation more intuitive and less distracting while maintaining precise control capability
Solution Approach 2:
The touch panel creates a digital copy of the spatial relationship between the displayed image and control input. By detecting contact positions on the touch panel and mapping them to corresponding positions in the displayed image, the system allows users to control zoom operations directly on the visual interface, eliminating the need to mentally translate between separate control device movements and image changes
2Manufacturing precision
If zoom magnification is adjusted by traditional methods, then control is possible, but the desirable observation position changes during zooming
Solution Approach 1:
The system continuously monitors the contact position on the touch panel and uses it as feedback to calculate and maintain the zoom center position. By detecting the relationship between touch coordinates and display image coordinates, the system dynamically adjusts the zoom operation to keep the observation point fixed, providing real-time feedback that ensures precise positioning during magnification changes
Solution Approach 2:
The system pre-establishes the coordinate transformation relationship between the touch panel and the display image. Before zooming occurs, the middle point between contact positions is calculated and set as the fixed zoom center, ensuring that the observation position remains stable throughout the zoom operation without requiring continuous adjustment during the process
Data Source
AI summary
A microscope includes a zoom optical system zooming over a sample, a zoom driving unit moving the optical system along an optical axis, an imaging unit imaging an observation image of the sample through the optical system, thereby generating image data on the sample, and a display unit displaying an image corresponding to the generated image data. A touch panel on a display screen of the display unit accepts an input corresponding to a contact position of an object. A driving control unit outputs a driving signal for changing a zoom magnification of the optical system by setting a middle point between contact positions on the touch panel corresponding to two position signals responsive to an input of the different contact positions as a zoom center position fixed without depending on the zoom magnification of the optical system when the two position signals are output from the touch panel.
