Abstract: Described herein is an ocular fundus imaging apparatus (11) including and an illumination module (140) and an imaging module (141). The illumination module (140) includes light sources (103, 104) configured to generate light at wavelengths within a desired spectral range. A first optical assembly is provided to shape and direct the light onto an eye (102) of a subject. A tuneable bandpass filter (109) selects a wavelength sub-interval within the desired spectral range. The imaging module (141) includes a second optical assembly to collect light returned from the eye (102) of the subject and to project the returned light from the eye (102) onto an image sensor (113). The second optical assembly includes one or more optical elements capable of compensating for ocular variation. The image sensor (113) is configured to image the returned light to generate an image of the ocular fundus at the wavelength sub-interval.

Abstract: A digital loupe system is provided which can include a number of features. In one embodiment, the digital loupe system can include a stereo camera pair and a distance sensor. The system can further include a processor configured to perform a transformation to image signals from the stereo camera pair based on a distance measurement from the distance sensor and from camera calibration information. In some examples, the system can use the depth information and the calibration information to correct for parallax between the cameras to provide a multi-channel image. Ergonomic head mounting systems are also provided. In some implementations, the head mounting systems can be configurable to support the weight of a digital loupe system, including placing one or two oculars in a line of sight with an eye of a user, while improving overall ergonomics, including peripheral vision, comfort, stability, and adjustability. Methods of use are also provided.

Abstract: An information processing apparatus includes: an information receiver configured to receive imaging data output from an imaging device; and a processing unit configured to generate a color image based on the received imaging data and control a display device to display the generated color image. The processing unit generates a detection frame constituted as plural regions based on the imaging data, controls the display device to display the generated detection frame as being superimposed on the color image, and displays a temperature for each of the plural regions.
