Abstract:
1. An image obtaining apparatus, comprising: a light source configured to irradiate a biological sample having a fluorescent label with an excitation light, the excitation light exciting the fluorescent label; an optical system including an objective lens, the objective lens being configured to magnify an imaging target of the biological sample; an image sensor configured to form an image of the imaging target magnified by the objective lens; a movement controller configured to move a focus position of the optical system in an extended range, the extended range being obtained by adding predetermined margins to both ends of the imaging target in a thickness range; and a light-exposure controller configured to expose the image sensor to light while moving the focus position of the optical system in the extended range, wherein the predetermined margins are set such that blurring amounts in biological sample images obtained by the image sensor for a plurality of fluorescent labels disposed at different positions in a thickness direction of the biological sample are approximately uniform.
