PROBLEM TO BE SOLVED: To photograph using a simple configuration and taking astigmatic components of an eye to be photographed into consideration.
SOLUTION: A fundus camera icnludes a driving mechanism which moves a focusing lens in a direction of the optical axis a fundus photographing optical system for photographing the fundus by an image pickup device a measurement data obtaining unit to obtain measurement data including astigmatic power of the eye measured by an auto ref keratometer a focus detection unit to receive luminous flux irradiating the fundus and to detect a focusing state of the fundus and a control unit to display the focusing state obtained from results detected by the focus detection unit as first focusing information. When the focusing lens is driven using the obtained measurement data, the control unit is arranged to set a focusing completion position of the focusing lens at a position corresponding to spherical equivalent power of the eye, and changes displays of focusing information based on the set position as second focusing information which is different from the first focusing information.
