Abstract
An image acquisition device according to the present invention includes: an image-acquisition-optical-system; a microlens array having microlenses; a phase filter modulating a phase distribution to light incident on the microlenses via the image-acquisition-optical-system; a light receiving unit receiving the light focused by the microlenses by light receiving elements; an adjusting unit switching between a first arrangement state in which the light receiving elements are arranged at back focal positions of the microlenses and a second arrangement state in which the light receiving elements are arranged in vicinities of principal point positions of the microlenses; a memory storing a point image intensity distribution at the light receiving unit in each of the arrangement states; and an arithmetic operation unit generating a processed image by using the point image intensity distribution and image information at the light receiving unit in each of the arrangement states.
