Specimen Image Observation Apparatus Alignment Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spectacle-type image display apparatuses face challenges in efficiently projecting a magnified image of a specimen onto the pupil while maintaining a clear view of the external world, often requiring precise alignment and focusing, which can be cumbersome and power-intensive.
Innovation Solution
An image observation apparatus that includes an imaging unit, a display, a condition determiner, and a controller, which captures a magnified image of a specimen and displays it only when the specimen is aligned at a specific distance and orientation, using a guide light to assist alignment and conserve power by projecting a guide screen when conditions are not met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a magnified image is projected onto the pupil using spectacle-type display apparatus, then the magnified image can be displayed in the field of view, but the alignment and focusing becomes cumbersome and power-intensive
Solution Approach 1:
The system performs preliminary alignment by projecting a guide screen with a guide mark before displaying the full magnified image. The guide screen helps the user align the specimen with the imaging unit's optical axis, preventing unnecessary power consumption from continuous full-image display when alignment is incorrect.
Solution Approach 2:
The system uses feedback by detecting whether the guide mark is imaged within a predetermined area on the display. Based on this detection result, the system determines whether to proceed with displaying the magnified image, creating a feedback loop that optimizes power usage based on actual alignment status.
2Reliability
If the magnified image is displayed continuously, then the observation can be maintained, but the power consumption increases and the external view may be obstructed
Solution Approach 1:
Instead of continuous display, the system uses periodic action by only displaying the magnified image when the guide mark is properly imaged within the predetermined area. This intermittent display approach maintains observation reliability when needed while reducing power consumption during misalignment or idle periods.
3Ease of operation
If the display is always active to show magnified image, then observation is maintained, but it obstructs the view of the external world
Solution Approach 1:
The system applies local quality by projecting the magnified image only in a specific portion of the field of view rather than the entire view. This allows the user to observe the magnified specimen in a localized area while maintaining awareness of the external world in the remaining field of view.

AI summary
An image observation apparatus 10 includes an imaging unit 30 that images a specimen K and obtains a magnified image of the specimen, a display 50 that displays an image, a condition determiner that determines whether a state of the specimen with respect to the imaging unit satisfies a specific condition, and a controller that displays the magnified image obtained by the imaging unit on the display when the condition determiner determines the state of the specimen with respect to the imaging unit satisfies the specific condition.
