A medical image viewer can render to a display, a three-dimensional view of patient anatomy, a multi planar reconstruction (MPR) view of the patient anatomy, and an intra-operational view. Some of the views can be synchronized to show a common focal point of the anatomy. Other embodiments are described and claimed.

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.

A method for processing 360-degree image data by a device for receiving a 360-degree video according to the present invention comprises the steps of: receiving 360-degree image data; obtaining information relating to an encoded picture and metadata from the 360-degree image data, wherein the metadata includes camera lens information; decoding a picture including a target circular area on the basis of the information relating to the encoded picture; and rendering the target circular area by processing same on the basis of the camera lens information.

An electrically controlled spectacle includes a spectacle frame and optoelectronic lenses housed in the frame. The lenses include a left lens and a right lens, each of the optoelectrical lenses having a plurality of states, wherein the state of the left lens is independent of the state of the right lens. The electrically controlled spectacle also includes a control unit housed in the frame, the control unit being adapted to control the state of each of the lenses independently.
