Abstract:
1. A microscope system comprising: a CPU which is programmed to perform functions including: capturing a plurality of observation images including a subject through an optical image forming system while relatively moving one of a stage loaded with the subject and the optical image forming system with respect to the other one of the stage and the optical image forming system; calculating a contrast value indicating a contrast level of each of the plurality of captured observation images; detecting a maximum contrast image whose calculated contrast value is maximum among the plurality of captured observation images; detecting a relative position of the stage and the optical image forming system; performing a correcting process of moving the one of the stage and the optical image forming system from the detected relative position corresponding to the detected maximum contrast image by a distance difference based on a time difference between capturing of one of the plurality of observation images and acquisition of the corresponding relative position of the stage and the optical image forming system in a direction opposite a direction of the relative movement of the one of the stage and the optical image forming system; and determining a focusing position using the corrected relative position and moving the one of the stage and the optical image forming system to the focusing position.
