Innovation Solution
The system generates and displays measuring result screens in real-time, showing object images and MTF curve images, allowing users to adjust focus and evaluate lens performance simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If serial work is used for lens performance evaluation, then measurement accuracy is maintained, but productivity deteriorates
Solution Approach 1:
The patent merges the object image display and MTF curve image display into a single integrated measuring result screen. This allows users to perform alignment, focusing, and lens performance evaluation simultaneously by viewing both the object image and MTF curve image together, eliminating the need for sequential operations while maintaining measurement accuracy.
Solution Approach 2:
The patent superimposes the MTF curve image onto the object image display in a layered manner, creating a multi-dimensional information presentation. The object image provides spatial context while the MTF curve image provides performance data, allowing users to correlate visual focus assessment with quantitative MTF values simultaneously.
2Loss of information
If separate displays are used for object image and MTF curve, then information clarity is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple information displays (object image and MTF curve image) into a single integrated screen interface. This reduces the number of separate display devices and control systems needed, simplifying the overall system architecture while maintaining clear presentation of all necessary information through strategic layout and labeling.
Data Source
AI summary
A MTF measuring system includes measurement result screen data indicative of an object image and an MTF curve image are generated in accordance with the object image data obtained by photographing the object and the MTF curve image data indicative of the MTF curve generated from MTF data that become an index to evaluate lens performance. The measurement result screen based on the generated measurement result screen data is displayed on a real time basis in the case of evaluation measurement operations of the lens performance. A user can grasp the necessity for a focus adjustment from the MTF curve image on the measurement result screen. If necessary, the user can adjust the focus of the object displayed together with the MTF curve image, and at the same time can evaluate the lens performance from the MTF curve image.
