  • Patent number: 9808150
    Abstract: An image processing apparatus includes: a tomographic image acquisition unit that acquires a first tomographic image of a subject's eye captured at a first time point that is a past time point; a tomographic image capturing unit that acquires a second tomographic image of the subject's eye captured at a second time point later than the first time point; and an image display control unit that, if one image capturing region of an image capturing region of the first tomographic image and an image capturing region of the second tomographic image is larger than the other image capturing region, performs control to provide, on an image display portion, a display of both a tomographic image of only a partial region of the one image capturing region which is a corresponding region corresponding to the other image capturing region and a tomographic image of the other image capturing region.

  • Patent number: 9510751
    Abstract: If an intraocular lens is inserted in an eye to be examined, characteristics of the eye to be examined are measured after increasing light intensity of visible light projected onto the eye to be examined to be higher than light intensity at the time of measurement of an eye to be examined in which no intraocular lens is inserted.

  • Patent number: 9277859
    Abstract: An optical tomographic imaging apparatus includes an instruction unit configured to issue an instruction on a size of an imaging range of a tomographic image, and a control unit configured to control a measurement light optical path length changing unit to perform alignment in a depth direction with respect an object after the instruction by the instruction unit, and change an optical path length of measurement light by a distance corresponding to a change of the size on which the instruction is issued.
