Microscope Stage Speed Control via Digital Zoom Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In microscope systems using digital cameras, changes in the viewing range of the image displayed on a display unit cause sudden changes in the moving speed of the observation image relative to the viewing range, disrupting specimen observation.
Innovation Solution
A microscope system with a stage controller that adjusts the moving speed of the stage based on the ratio of the viewing range set by the viewing-range setting unit relative to the maximum image-acquisition area, ensuring stable observation by maintaining consistent moving speed before and after changes in the viewing range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the stage is driven when the viewing range is changed via digital zooming or camera switching, then the observation can be maintained, but the moving speed of the observation image suddenly changes disrupting specimen observation
Solution Approach 1:
The system changes the stage drive speed parameter based on the digital zoom ratio. When digital zooming is applied, the stage drive speed is reduced proportionally to compensate for the increased image magnification, thereby maintaining a constant observed movement speed and preventing disruption to specimen observation
Solution Approach 2:
The system uses feedback from the digital zoom ratio and camera switching state to dynamically adjust the stage drive speed. The control unit receives information about the current viewing range settings and automatically modifies the stage movement parameters to maintain consistent observation conditions
2Adaptability or versatility
If digital zooming or camera switching is performed to change the viewing range, then the display magnification is adjusted, but the stage drive speed remains constant causing sudden changes in observation image speed
Solution Approach 1:
The system makes the stage drive speed dynamic rather than fixed. The drive speed automatically adapts to the current digital zoom ratio and camera configuration, allowing the system to maintain smooth observation across different viewing ranges without sudden speed changes that would disrupt the observer

AI summary
A microscope system including a stage on which a specimen is mounted and that can be moved in a direction that intersects with an optical axis of illumination light irradiated on the specimen; an observation optical system that acquires an image of the specimen on which the illumination light is irradiated; a viewing-range setting unit that sets a viewing range of the image acquired by the observation optical system and displayed on a display unit; a ratio calculating unit that calculates a ratio of the viewing range of the image, which is set by the viewing-range setting unit, relative to a maximum image-acquisition area that can be captured by the observation optical system; and a stage controller that controls a moving speed of the stage in accordance with the ratio calculated by the ratio calculating unit.
