Provided is an imaging apparatus including: a first scanning unit and a second scanning unit, subjecting a measuring beam, which is obtained by splitting a light source beam, to a back-and-forth scan in a predetermined area on a fundus in a first direction and a second direction, respectively； a scanning control unit controlling the first scanning unit and the second scanning unit so as to simultaneously execute scans； a depth information acquisition unit obtaining information on the fundus in a depth direction based on interference beam between return beam from the fundus and a reference beam； an image generation unit generating a tomographic image in the predetermined area through use of output from the depth information acquisition unit and a control signal supplied by the scanning control unit； and a display unit displaying the generated image. In the imaging apparatus, a tomographic image along a freely-set line within the predetermined area can be generated through use of the output from the depth information acquisition unit, and Is repeatedly displayed on the display unit before depth information is acquired through the back-and-forth scans simultaneously executed by the two scanning units.
