Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices require expertise to adapt a digital camera to a microscope, making them difficult for inexperienced users, and they often suffer from low signal-to-noise ratio and resolution due to small pixel size and inadequate use of sensor area.
Innovation Solution
An imaging device with a controller that automatically adjusts the active area of the image sensor based on the camera adapter's magnification and sensor area, allowing users to choose magnification and sensor size independently, optimizing image quality and preventing black borders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the pixel size is reduced to increase resolution, then the resolution of the digital camera is improved, but the signal-to-noise ratio deteriorates
Solution Approach 1:
The controller pre-determines the optimal active area size based on the camera adapter's magnification and the sensor's total area before image capture. This preliminary configuration ensures that the active area is optimally sized to capture sufficient light while maintaining resolution, preventing the signal-to-noise ratio from deteriorating even when using small pixels.
2Adaptability or versatility
If a camera adapter is used to adapt the digital camera to the microscope, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The controller automatically determines the magnification of the camera adapter and calculates the optimal active area size without user intervention. The system self-configures by reading the magnification value and sensor area, then autonomously sets the active area parameters, eliminating the need for manual adjustment and reducing operational complexity for users.
Solution Approach 2:
The controller dynamically changes the active area parameters (size and position) based on the camera adapter's magnification value. By automatically adjusting these parameters according to the magnification, the system maintains optimal imaging performance across different adapters without requiring user expertise in optical configuration.
3Ease of operation
If the active area size is not properly adjusted to match the sensor area and magnification, then the ease of operation is improved, but black borders appear in the image
Solution Approach 1:
The controller uses feedback from the determined magnification value and sensor area to automatically adjust the active area size. This closed-loop configuration ensures that the active area precisely matches the optical image area, preventing black borders while maintaining ease of operation, as the system self-corrects based on the detected parameters.

AI summary
An imaging device for imaging a sample includes an image sensor having a sensor area for receiving detection light from the sample, and configured to generate an image from the detection light received by an active area. The active area is at least a part of the sensor area of the image sensor. The imaging device further includes a camera adapter configured to mount the image sensor, and a controller configured to determine a magnification of the camera adapter, determine a size of the sensor area of the image sensor, and set a size of the active area based on the magnification of the camera adapter and the size of the sensor area.
