PROBLEM TO BE SOLVED: To smoothly observe any part of the eye ground as an inspector wants to do.
SOLUTION: The ophthalmic imaging apparatus has an irradiation means to irradiate an examined eye with light from a light source issuing light flux with a low coherent length, a scanning means to scan the measurement light, an optical path difference change means to change the optical path difference between reference light and measurement light irradiating the examined eye, an interference optical system to obtain the tomogram image of the examined eye by receiving interference light obtained through the integration of the reflective light of the reference and measurement light, and a display means to display the tomogram image. The apparatus is also provided with a position specifying means to specify an arbitrary point on the tomogram image displayed on the display means and a control means to change the optical path differences by the optical path difference change means from the information of specified position or of its movement from the position specifying means, and to thereby change the depth position of the examined eye relative to the optical path of reference light.
