Abstract
The fundus observation apparatushas a function to form tomographic images and 3-dimensional images of a fundus Ef by scanning signal light LS as well as a function to form a moving image (observation image K) of a fundus Ef during OCT measurement. Furthermore, the fundus observation apparatusincludes an x-correction partand a y-correction partfor correcting a position in the fundus surface direction of the 3-dimensional image based on the observation image K, and a z-correction partfor correcting the position in the fundus depth direction of a 3-dimensional image, based on a tomographic image Gi of the fundus Ef based on the detection results of interference light LC of separately scanned signal light LS and reference light LR.
