An information processing apparatus includes a first acquisition portion acquiring a front image of an eye fundus, a second acquisition portion acquiring an En-Face image on the basis of a plurality of tomographic images of the eye fundus, and a display control portion controlling a display unit to display the En-Face image in a superimposed relation to the front image. The display control portion changes a depth range, at the eye fundus, of the En-Face image superimposed on the front image.

Information processing apparatus

A tomographic-image pickup unit is controlled so as to capture a tomographic image in response to a signal input from a signal input unit. Then, a display unit is controlled so as to display the captured tomographic image. An eyeground-image pickup unit is controlled so as to capture a two-dimensional image in response to a signal input from the signal input unit while the tomographic image is displayed on the display unit. Therewith, the user can more easily perform imaging, and the time load on the subject is reduced.

Eyeground imaging apparatus and control method therefor

Provided is an ophthalmologic apparatus including: an acquisition unit configured to acquire tomographic information of an eye to be examined using information on interference light between return light from the eye to be examined, which is irradiated with measurement light, and reference light; and a vitreous structure detection unit configured to detect a vitreous structure of the eye to be examined using tomographic information of the eye to be examined that is acquired after at least one of the difference in optical path length between the measurement light and the reference light and the in-focus position is controlled, wherein the acquisition unit is configured to acquire tomographic information of the vitreous structure.

Ophthalmologic apparatus, and ophthalmologic imaging method

An interactive control apparatus for controlling an OCT imaging apparatus instructs, in response to detection of a first instruction signal from a pointer device, a specific action to the OCT imaging apparatus according to selected icon displayed on a display unit, and instructs, in response to detection of a second instruction signal from the pointer device, a specific action to the OCT imaging apparatus according to a preparation status of the OCT imaging apparatus when the second instruction signal is detected.

Interactive control apparatus

A diagnosis support apparatus comprises an acquiring unit that acquires a plurality of examination data items having different examination dates, a setting unit that sets an extraction condition for examination data items, an extracting unit that extracts, from the plurality of acquired examination data items, examination data items corresponding to the set extraction condition, and a displaying unit that arranges and displays the extracted examination data items, wherein the setting unit sets the extraction condition based on an interval between examination dates of examination data items.

Diagnosis support apparatus and method

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.

Ophthalmic apparatus

An image processing apparatus includes a tomographic signal obtaining unit that obtains tomographic signals of light beams, the light beams respectively having a different polarization from each other and being obtained by splitting combined light obtained by combining return light and reference light, the return light being from an object to be inspected that is irradiated with measuring light, and an information obtaining unit that obtains three-dimensional polarization tomographic information, and three-dimensional motion contrast information of the object to be inspected, by commonly using at least one of the obtained tomographic signals. In addition, an extracting unit extracts a specific region of the object to be inspected using the obtained three-dimensional polarization tomographic information, and an image generating unit generates a motion contrast enface image of the extracted specific region using the obtained three-dimensional motion contrast information.
