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.

Abstract: Disclosed is an image acquiring device, including a liquid lens having a shape changed by pressurization, a membrane provided to one surface of the liquid lens, the membrane forming a pressurization surface, a pressurizing member provided to an outside of the membrane, and a support wire provided across a prescribed region of an outer surface of the pressurizing member, the support wire moving the pressurizing member toward the membrane by contracting by conduction, the support wire moving the pressurizing member toward an opposite side of the membrane by expanding. Accordingly, the present invention solves a problem of a mismatched focus in a close-up photo and minimizes an increasing volume of the image acquiring device.
