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.

6. A sample-image acquisition method comprising:
-
a movement control step of moving a relative position, which is movable in a plane direction perpendicular to an optical-axis direction as a position relative between an image of a sample and an image taking device used for creating said image of said sample after being enlarged by an 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 step of acquiring a sample image by exposing said image taking device to said sample while said movement control step is being carried out to move said relative position in a circular arc at a constant speed in said plane direction and move 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.

7. A non-transitory computer readable storage medium storing a sample-image acquisition program to be executed by a computer to perform:
-
a movement control step of moving a relative position, which is movable in a plane direction perpendicular to an optical-axis direction as a position relative between an image of a sample and an image taking device used for creating said image of said sample after being enlarged by an 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 step of acquiring a sample image by exposing said image taking device to said sample while said movement control step is being carried out to move said relative position in a circular arc at a constant speed in said plane direction and move 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.
