    摘要： The present disclosure relates to a prism apparatus, and a camera apparatus including the same. The prism apparatus according to an embodiment of the present disclosure may include: a prism configured to reflect input light toward a first reflected direction; a first actuator configured to change an angle of the prism about a first rotation axis to change the first reflected direction based on a first control signal; a lens configured to output the light reflected by the prism toward a second reflected direction; and a second actuator configured to change an angle of the lens about a second rotation axis to change the second reflected direction based on a second control signal. Accordingly, it is possible to implement the optical image stabilization (OIS) for the prism.

    摘要： The present invention relates to a camera and a terminal comprising same. A camera and a terminal comprising same according to an embodiment of the present invention comprise: a lens device including a micromirror array; and a processor for outputting, to the micromirror array in the lens device, a curvature control signal for curvature change, wherein the micromirror array includes a plurality of micromirrors including a first micromirror and a second micromirror, and the second micromirror is closer to the outer periphery thereof than the first micromirror and has a larger tilting angle according to the control signal than the first micromirror. Accordingly, focus can be changed using the micromirror array.

    摘要： The present disclosure relates to an imaging lens, a camera module and an electronic device including the same. The imaging lens according to an embodiment of the present disclosure includes a catadioptric lens on which light is incident from an object side, and through which light is reflected and emitted from the inside; and a lens group including a plurality of lenses for transmitting the light emitted from the catadioptric lens to an image surface, wherein the catadioptric lens includes: an incident surface on which light is incident from the object side; a second mirror surface which is formed concave toward the object side, and reflects the light incident on the incident surface to a first mirror surface in the object side; the first mirror surface which is formed, at a central portion of the incident surface, convex toward an image side, and reflects the light reflected from the second mirror surface toward the image side; and an exit surface through which the light reflected from the first mirror surface is emitted, wherein all of the lens group is disposed between the first mirror surface and the second mirror surface based on an optical axis. Accordingly, it is possible to increase the brightness of the lens, increase resolution, suppress an increase in thickness, and reduce tolerance due to mirror assembly.
