A distance measurement camera 1 contains a first optical system OS1 for collecting light from a subject 100 to form a first subject image, a second optical system OS2 for collecting the light from the subject 100 to form a second subject image, an imaging part S for imaging the first subject image formed by the first optical system OS1 and the second subject image formed by the second optical system OS2, and a distance calculating unit 4 for calculating the distance to the subject 100 based on the first subject image and the second subject image imaged by the imaging part S. The distance calculating part 4 calculates the distance to the subject 100 based on an image magnification ratio between a magnification of the first subject image and a magnification of the second subject image.

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.

The present invention relates to a distance measuring apparatus including an imaging device and a calculation unit calculating a distance to a subject on the basis of an electrical signal. The imaging device includes a signal acquisition unit that acquires a first electrical signal based on a beam that has passed through a first region off the center of the exit pupil in a predetermined direction; a second electrical signal based on a beam that has passed through a second region off the center of the exit pupil in a direction opposite to the predetermined direction; and a third electrical signal based on a beam that has passed through a region eccentric from the first region in the direction opposite to the predetermined direction. The calculation unit performs a signal correction process for generating a first corrected signal and a distance calculation process for calculating the distance.
