OPHTHALMIC APPARATUS, OPHTHALMIC SYSTEM, PROCESSING APPARATUS, AND BLOOD FLOW VELOCITY CALCULATION METHOD An ophthalmic apparatus includes irradiation means configured to irradiate a subject's eye with a measurement beam scanned by scanning means (119), acquisition means (125) configured to acquire an image of the subject's eye based on a return beam returned from the subject's eye, of the measurement beam irradiated by the irradiation means, and calculation means (125) configured to calculate a blood flow velocity of the subject's eye based on a displacement between a position of a blood cell in a first image obtained by the acquisition means (125) and a position of the blood cell in a second image obtained by the acquisition means (125) at a different time from the first image and on a difference between time when an image of the blood cell in the first image is obtained and time when an image of the blood cell in the second image is obtained. |
