The patent filed by Hamamatsu Photonics KK describes a focal position estimation system that utilizes machine learning to estimate the focal position when in focus corresponding to an estimation target image. The system includes an estimation target image acquisition unit and a focal position estimation unit that outputs a feature quantity of the image and estimates the focal position using a feature quantity output model generated from learning images associated with focal position information. The feature quantities of different learning images are compared to perform machine learning for accurate estimation.
Furthermore, the system can be applied in various fields such as semiconductor inspection and biological observation systems. In the semiconductor inspection system, the focal position estimation system is used in conjunction with a mounting unit for semiconductor devices and an inspection unit. Similarly, in the biological observation system, the focal position estimation system is combined with a mounting unit for biological samples and an observation unit. The patent also covers a focal position estimation method and a non-transitory computer-readable storage medium storing a focal position estimation program that enables a computer to operate as a focal position estimation system. The program allows for the acquisition of an estimation target image, output of a feature quantity, and estimation of the focal position using machine learning techniques.
