fixation target projecting part configured to display a fixation target for fixating an eye and configured to project the displayed fixation target onto a fundus oculi,

projection position changing part configured to change the display position of said fixation target so as to change the projection position of the fixation target on the fundus oculi,

first image forming part operable to form a 2-dimensional image of the surface of a fundus oculi with said fixation target projected based on optically captured data;

second image forming part operable to form a tomographic image of a fundus oculi based on data captured by an optical scan;

displaying part configured to display the formed 2-dimensional image; and

operation part configured to specify a position on said displayed 2-dimensional image, wherein said projection position changing part is configured to change the display position of said fixation target to the position specified by said operation part,

wherein when macula area of the fundus oculi is specified by said operation part, said projection position changing part is configured to determine whether or not the formed tomographic image includes a concave portion, extract an image region of which the concave portion is in the central position, about the tomographic image including the concave portion, and instruct said fixation target projection part to project said fixation target onto the position on the fundus oculi based on the extracted image region as the macula area,

wherein said second image forming part is configured to form a new tomographic image to be substantially centered at the concave portion of the fundus oculi of an eye, the eye being fixated by the projected fixation target.
