Abstract: 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.

Abstract: 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 rear mirror comprising a transmission area and a reflection area for reflecting light incident from an object side to the object side; a front mirror for reflecting the light reflected from the reflection area of the rear mirror to an image side; and a lens group comprising a plurality of lenses for transmitting the light reflected from the front mirror to an image surface, wherein the lens group is all disposed between the rear mirror and the front mirror based on an optical axis, thereby increasing the brightness of the lens, enhancing the resolution, and suppressing the increase in thickness.
