Abstract
It is possible to generate image data of a biological tissue in a short time. A focus information generating device () receives a first reflected light beam (Lr) split from a reflected light beam (Lr) and a second reflected light beam (Lr) passing through a pin-hole plate (). A signal processing unit () calculates a uniform reflectance (RE) representing a light amount ratio of the second reflected light beam (Lr) to the first reflected light beam (Lr) along with a sum signal (SS) and a difference signal (SD). An integrated control unit () detects a position (Z) corresponding to a top surface (A) of a cover glass () on the basis of the sum signal (SS) and the difference signal (SD) and detects a position (Z) representing a biological tissue () on the basis of the sum signal (SS) and the uniform reflectance (RE). As a result, the integrated control unit () can calculate a cover distance (DM) from the top surface (A) of the cover glass () to the biological tissue () in a pathology glass slide () on the basis of the positions (Z) and (Z).
