<P>PROBLEM TO BE SOLVED: To provide a focal position information detector, a microscope device and a focal position information detection method which enable accurate detection of focal position information. <P>SOLUTION: A focal position information detector 1 includes an image sensor 2, a stage 4, a light source 6, a light source control section 9, and a focal position information acquisition section 10. The image sensor 2 includes plural pixel lines and operates in a rolling shutter mode. The stage 4 faces the image sensor 2 via a microscopic optical system 3 and is movable in the optical axis direction of the microscopic optical system 3. The light source 6 lights the stage 4. The light source control section 9 makes the light source 6 emit light intermittently at an interval longer than light reception time of the pixel lines. The focal position information acquisition section 10 acquires focal position information on the microscopic optical system 3 based on an image imaged by the image sensor 2 while moving the stage 4. <P>COPYRIGHT: (C)2012,JPO&INPIT |
