Abstract: An optical coherence tomography apparatus includes a control unit configured, before a tomographic image to be stored is obtained using the output from the light receiving unit during a period in which the measurement light is scanned in a first scanning pattern for scanning an image capturing region of the subject eye, to control the optical scanning unit so as to repeatedly scan the measurement light in a second scanning pattern for scanning the measurement light over at least part of the image capturing region in a scanning time shorter than a scanning time of the first scanning pattern and to control the driving unit so as to drive the focusing unit using the output from the light receiving unit during a period in which the measurement light is repeatedly scanned in the second scanning pattern.

Abstract: An ophthalmic apparatus includes a control unit configured to control a scanning unit so that scanning lines of a first field and scanning lines of a second field are alternately arranged in a direction crossing the scanning lines, and a detection unit configured to, in a case where one of first front images of the first field is selected as a reference image, detect movement of the subject's eye using information indicating a position gap between the reference image and the first front images, and detect the movement of the subject's eye using information indicating a position gap between the reference image and second front images of the second field and information indicating a difference in position between the first field and the second field.

Abstract: The present invention defines a method of correcting for eye movement during optical coherence tomography imaging. The method includes imaging (by scanning) a fundus of an eye to obtain a fundus image (for example, using an SLO); scanning the fundus to obtain a plurality of tomographic images (for example, using OCT); determining, at predetermined intervals, an alignment of the tomographic images with respect to the fundus image, and, if it is determined that there is a misalignment, determining the number of tomographic images that have been scanned in the predetermined interval since the previous alignment determination; determining the offset by which the tomographic images are misaligned; applying the offset to the next tomographic image to be scanned and rescanning the determined number of tomographic images that were scanned during the interval between misalignment being determined and offset being applied.

Abstract: An information processing apparatus includes an acquisition unit configured to acquire a plurality of data sets each of which includes a plurality of pieces of tomographic data that represents a section of a fundus, the plurality of data sets not including the same tomographic data as each other, a first generation unit configured to generate at least one motion contrast image from each of the plurality of data sets acquired by the acquisition unit, without generating a motion contrast image from across the data sets acquired by the acquisition unit, and a second generation unit configured to generate a single motion contrast image representing a cross section at a predetermined position in the fundus, based on the motion contrast image generated from at least one of the plurality of data sets.
