Abstract:
1. An optical coherence tomographic imaging apparatus comprising: an image acquisition unit configured to acquire a plurality of images of a subject's eye at different times; a tomographic image acquisition unit configured to acquire a plurality of tomographic images of the subject's eye based on interference light obtained by interfering return light from the subject's eye irradiated with measuring light via a scanning unit and reference light corresponding to the measuring light; a movement amount acquisition unit configured to acquire the amount of subject's eye movement based on the plurality of images; a determination unit configured to determine whether the amount of subject's eye movement before a scan by the scanning unit exceeds a threshold value; and a control unit configured to control, in a case the amount of subject's eye movement before the scan is equal to or smaller than the threshold value, the scanning unit to perform scanning position correction between the scan and the next scan based on the amount of movement.
