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: A camera for an electronic device, which is compact and exerts high performance is disclosed. The camera for an electronic device includes a housing, a lens assembly mounted movably inside the housing, an actuator configured to move the lens assembly relative to the housing, and a guide provided in the lens assembly and the housing, and configured to guide the relative movement of the lens assembly. The guide includes a first guide configured to support a first surface of the lens assembly with respect to the housing, for the relative movement of the lens assembly, and a second guide configured to support a second surface of the lens assembly, different from the first surface, with respect to the housing, for the relative movement of the lens assembly.

Abstract: The present invention relates to a prism module, a camera comprising same, and an image display device. A prism module, according to one embodiment of the present invention, comprises: a prism holder having a prism fixed to a first surface thereof; a yoke coupled to a second surface of the prism holder; a driving magnet seated on the yoke; a sensor magnet disposed on the yoke; a hall sensor disposed to be spaced apart from the sensor magnet; and a sensor magnet support member to which the sensor magnet is attached. Thereby, it is possible to precisely detect a magnetic field.

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.
