1. An image processing apparatus processing three-dimensional image data generated based on a photoacoustic wave generated from inside of a subject by radiating light to the subject, the image processing apparatus comprising:
a memory configured to store a program; and
one or more processors which are configured to, by executing the program, function as a plurality of units comprising:
(1) a first three-dimensional image acquisition unit configured to acquire first three-dimensional image data in which a blood vessel region corresponding to a first substance in the subject is extracted from the three-dimensional image data;
(2) a second three-dimensional image acquisition unit configured to acquire second three-dimensional image data in which a lymphatic region corresponding to a second substance different from the first substance in the subject is extracted from the three-dimensional image data;
(3) a first two-dimensional image acquisition unit configured to acquire, from the first three-dimensional image data, (a) first two-dimensional image data of the blood vessel region and (b) first depth position data of each part of the blood vessel region in a first depth direction, the first depth direction being a direction oriented inward with respect to the subject;
(4) a second two-dimensional image acquisition unit configured to acquire, from the second three-dimensional image data, (a) second two-dimensional image data of the lymphatic region and (b) second depth position data of each part of the lymphatic region in a second depth direction, the second depth direction being a direction oriented inward with respect to the subject; and
(5) a display control unit configured to combine and display (a) the first two-dimensional image data in accordance with the first depth position data and (b) the second two-dimensional image data in accordance with the second depth position data.
