Abstract: A prism apparatus, and a camera and an image display apparatus including the same are disclosed. The prism apparatus includes: a first prism configured to reflect input light toward a first reflected direction, a first actuator configured to change an angle of the first prism about a first rotation axis to change the first reflected direction based on a first control signal, a second prism configured to reflect the light reflected from the first prism toward a second reflected direction, and a second actuator configured to change an angle of the second prism about a second rotation axis to change the second reflected direction based on a second control signal.

Abstract: Disclosed are a camera and an image display apparatus including the same. The camera according to an embodiment of the present invention comprises: a first optical structure configured to refract and reflect a first input beam to output a second beam with a width smaller than a width of the first input beam; and a second optical structure configured to refract and reflect the second beam from the first optical structure to output a third beam with a width greater than the width of the second beam, wherein the first optical structure comprises a first reflection surface configured to reflect the first input beam, and wherein a first angle between the first reflection surface and the second beam and a second angle between an orthogonal surface orthogonal to the first input beam and the first reflection surface are each greater than 0° and smaller than 45°. Accordingly, a thickness of the camera may be reduced.
