Abstract
A hologram image of an object is acquired in a state where the object is accommodated in a concave portion provided in a container with a bottom surface of the concave portion being curved. A phase image is generated from the hologram image. Processing of subtracting a phase component derived from a polynomial indicating a shape of the bottom surface of the concave portion from the phase image is performed to acquire a processed phase image.
