Abstract:
1. A sample-image acquisition apparatus comprising: an image taking device on which an image of a sample is created after being enlarged by an objective lens; a movement control section configured to move a relative position, which is movable in a plane direction perpendicular to an optical-axis direction as a position relative between said image of said sample and said image taking device used for creating said image of said sample after being enlarged by said objective lens having a focal point movable within a range including said sample, in said plane direction changed for each position of said focal point in said optical-axis direction while moving said focal point in said optical-axis direction within said range; and a sample-image acquisition section configured to acquire a sample image by exposing said image taking device to said sample while said movement control section is moving said relative position in a circular arc at a constant speed in said plane direction and moving said focal point in said optical-axis direction such that a fluorescent marker of the sample is in focus for at least a portion of the exposure and subsequently blurred for another portion of the exposure.
