Abstract: An ophthalmic device may include: a measurement optical system which includes a light-emitting optical system including a light source and a light-receiving optical system including a light receiving element; an arithmetic device configured to calculate an eye refractive power of the subject eye; a beam deflecting member arranged in an optical path of the measurement optical system and configured to deflect beam emitted from the light source, and a driving device configured to drive the beam deflecting member so that the beam emitted from the light source is scanned in a ring shape onto the subject eye. The beam deflecting member may be disposed so that traveling directions of the beam emitted from the light source intersect with each other between the subject eye and the beam deflecting member when the beam deflecting member is driven by the driving device.

Abstract: An image processing device may include a first image input unit to which a first photographed image obtained by photographing a specific part of the subject eye is inputted, a second image input unit to which a second photographed image obtained by photographing the specific part is inputted, and display unit configured to display a synthesized image obtained by synthesizing the first and second photographed image. The synthesized image may be partitioned into at least a first region and a second region by a first boundary line. The display unit may be configured to display, in the first region, at least a portion which is a part of the first photographed image and corresponds to the first region. The display unit may be configured to display, in the second region, at least a portion, which is a part of the second photographed image and corresponds to the second region.

Abstract: An optical coherence tomographic device may include: a light source; a measurement light generator that generates measurement light and generates reflected light from a target region in a scattering sample by irradiating the target region with the measurement light; a reference light generator that generates reference light; an interference light generator that generates interference light by combining the reflected light and the reference light; an interference light detector that detects the interference light and generates interference signals by converting the interference light; and a processor. The processor may cause the OCT device to execute: acquiring tomographic images for a same cross section in the target region in time series from the interference signals; calculating an entropy of the generated interference signals based on the tomographic images; and specifying a dynamic part in the tomographic images based on the calculated entropy.

Abstract: A ophthalmic apparatus may include: a first light source configured to output first light to be irradiated to an anterior segment of a subject eye; and a second light source configured to output second light to be irradiated to a retina of the subject eye. The apparatus may be configured capable of executing a first examination using the first light reflected from the anterior segment and a second examination using the second light reflected from the retina. A wavelength of the second light outputted from the second light source may be smaller than a wavelength of the first light outputted from the first light source.

Abstract: An ophthalmic apparatus may include: a wavelength sweeping light source; a reference optical system; a calibration optical system; a light receiving element configured to receive calibration interference light which is a combination of calibration light and reference light; and a signal processor configured to sample a calibration interference signal outputted from the light receiving element when it receives the calibration interference light. The signal processor may sample the calibration interference light in at least first and second frequency bands, which are different and used for measuring a specific region of a subject eye. The ophthalmic apparatus calculates a difference between first and second waveforms, the first waveform being a waveform of the calibration interference signal that is sampled in the first frequency band and Fourier transformed, the second waveform being a waveform of the calibration interference signal that is sampled in the second frequency band and Fourier transformed.
