Abstract: A present disclosure relates to a prism apparatus, a camera apparatus and an image display apparatus including same. The prism apparatus according to one embodiment of the present disclosure includes a prism holder for fixing a prism to a first surface; a yoke of which a first surface is attached to a second surface of the prism holder which is rear surface of the first surface of the prism holder; a drive magnet attached to a second surface of the yoke which is rear surface of the first surface of the yoke; a sensor magnet disposed above the yoke; a hall sensor spaced apart from the sensor magnet; and a sensor magnet supporter to which the sensor magnet is attached. Accordingly, the magnetic field is detected accurately.

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.
