Abstract:
A fundus camera of which the operability in alignment when photographing a fundus is enhanced includes a photographing optical system having a photographing optical axis which photographs the fundus, a fundus observation optical system picking up a fundus observation image, an anterior-segment observation optical system picking up an anterior-segment observation image, a photographing unit housing the optical systems, a moving mechanism moving the unit for alignment of the axis, a display unit, and a controller controlling the display unit and making display switching between the images on a screen of the display unit, wherein the controller includes a program for forming and displaying a reticle mark both in displaying the fundus observation image and in displaying the anterior-segment observation image while forming and displaying an alignment mark of which a relative distance from the reticle mark varies with an alignment deviation amount of the axis with respect to an eye.
