Claim 21:
22. A projection unit for a microscope provided with an objective, a tube lens, and an eyepiece, the projection unit comprising:
an imaging apparatus that acquires digital image data of a sample based on light therefrom;
a projection apparatus that projects a projection image including (i) a first assistance image onto an image plane on which an optical image formed by the tube lens is formed, and (ii) a second assistance image indicating a position within the first assistance image that corresponds to the optical image; and
a processor that performs processes,
wherein:
the processes include generating a projection image data representing the projection image,
the first assistance image is an image of the sample in which a region wider than an actual field of view corresponding to the optical image is seen,
the first assistance image is projected onto a portion of the image plane that is close to an outer edge of the optical image, and
the projection apparatus projects the second projection image onto the position within the first assistance image projected onto the image plane.
