Fundus camera

A fundus camera comprising:

• a first lens group having a first side and a second side opposite to the first side, wherein the first side faces an inspected eyeball;
• an eyeball-offset detection device detecting a relative position of the first lens group and the inspected eyeball;
• an annular illumination device arranged in the second side of the first lens group and including a plurality of illumination elements arranged annularly, wherein an optical axis of the first lens group passes through a hollow region of the annular illumination device;
• a processor electrically connected with the eyeball-offset detection device and the annular illumination device, working out an offset vector according to the relative position of the first lens group and the inspected eyeball, and selectively activating at least one of the plurality of illumination elements to generate an illumination light according to the offset vector, wherein the illumination light passes through the first lens group to a fundus of the inspected eyeball, and the fundus reflects the illumination light to form an imaging light;
• a second lens group coaxially arranged in the second side of the first lens group;
• an image sensor arranged in a light exit side of the second lens group, wherein the imaging light passes the first lens group and the second lens group and converges on the image sensor in sequence to form a fundus image;
• and
• a display device electrically connected with the image sensor and displaying the fundus image formed in the image sensor.
