Dynamic Translation Factor for Microscopy Slide Panning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current microscopy slide image manipulation on computer screens requires significant user input to pan across large images, as the motion input needed to move from one end of the image to the other is excessive compared to moving an actual slide, due to the disparity between actual slide motion and digital representation motion.
Innovation Solution
A method and system that calculates a translation factor based on image magnification and screen resolution, allowing electronic input devices to proportionally move microscopy slide images on the screen, mimicking the motion as if viewed under a microscope, with options for varying magnifications and input devices such as keyboards, mice, and touch-screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the microscopy slide image is displayed at high magnification on a computer screen, then the detail visibility is improved, but the user input required to pan across the image increases excessively
Solution Approach 1:
The system dynamically changes the translation factor parameter based on the current magnification level. When magnification increases, the translation factor is adjusted to reduce the distance the input device must be moved, maintaining a consistent relationship between physical slide motion and digital image motion across all magnification levels.
Solution Approach 2:
The translation factor is made dynamic rather than static, automatically adjusting according to the current magnification setting. This allows the system to adapt to changing viewing conditions, ensuring that panning behavior remains intuitive whether viewing at low or high magnification.
2Ease of operation
If the translation factor is increased to reduce user input motion, then the ease of operation is improved, but the accuracy of motion correspondence between physical slide and digital image deteriorates
Solution Approach 1:
The translation factor parameter is dynamically adjusted based on magnification level. At higher magnifications, the translation factor is increased to reduce panning effort, while at lower magnifications it is decreased to maintain precise motion correspondence, optimizing both ease of operation and accuracy for each viewing condition.
Solution Approach 2:
Rather than using a fixed translation factor, the system employs a dynamic translation factor that automatically adapts to the current magnification setting. This ensures that the relationship between input device motion and image motion remains appropriate for the current viewing level, balancing ease of operation with motion accuracy.
3Measurement precision
If the image magnification is increased digitally, then the detail observation capability is improved, but the amount of user input required to navigate the image increases
Solution Approach 1:
The translation factor parameter is changed in response to magnification changes. When digital zoom increases magnification to reveal more detail, the translation factor is simultaneously adjusted to reduce the distance required for panning operations, preventing navigation time from increasing despite higher magnification.
