An optical coherence tomographic imaging apparatus comprising: an image acquisition means configured to acquire a plurality of images of a subject's eye at different times; a tomographic image acquisition means configured to acquire a plurality of tomographic images of the subject's eye based on interference light produced by the interference between return light from the subject's eye irradiated with measuring light via a scanning means (122-1, 122-2), and reference light corresponding to the measuring light; a movement amount acquisition means configured to acquire the amount of subject's eye movement based on the plurality of images; a determination means configured to determine whether the acquired amount of subject's eye movement exceeds a threshold value; and a control means configured to control the scanning means (122-1, 122-2) to scan the subject's eye by a plurality of scans and to perform scanning position correction based on the acquired amount of subject's eye movement; characterized in that the control means is further configured to control, in a case the amount of subject's eye movement is acquired during a scan by the scanning means (122-1, 122-2) at a first timing (Di), the scanning means (122-1, 122-2) to delay the scanning position correction corresponding to the acquired amount of subject's eye movement until a second timing (Ci) so as to perform the scanning position correction between completion of the scan and a next scan and to control, in a case where the determination means determines that the amount of subject's eye movement exceeds the threshold value, the scanning means (122-1, 122-2) to scan again from a scanning position before the subject's eye movement occurred. an image acquisition means configured to acquire a plurality of images of a subject's eye at different times; a tomographic image acquisition means configured to acquire a plurality of tomographic images of the subject's eye based on interference light produced by the interference between return light from the subject's eye irradiated with measuring light via a scanning means (122-1, 122-2), and reference light corresponding to the measuring light; a movement amount acquisition means configured to acquire the amount of subject's eye movement based on the plurality of images; a determination means configured to determine whether the acquired amount of subject's eye movement exceeds a threshold value; and a control means configured to control the scanning means (122-1, 122-2) to scan the subject's eye by a plurality of scans and to perform scanning position correction based on the acquired amount of subject's eye movement; characterized in that the control means is further configured to control, in a case the amount of subject's eye movement is acquired during a scan by the scanning means (122-1, 122-2) at a first timing (Di), the scanning means (122-1, 122-2) to delay the scanning position correction corresponding to the acquired amount of subject's eye movement until a second timing (Ci) so as to perform the scanning position correction between completion of the scan and a next scan and to control, in a case where the determination means determines that the amount of subject's eye movement exceeds the threshold value, the scanning means (122-1, 122-2) to scan again from a scanning position before the subject's eye movement occurred.
