Prism apparatus, and camera apparatus including the same

A camera apparatus comprising:

• a gyro sensor configured to sense a movement of the camera apparatus;
• a dual prism apparatus configured to direct input light;
• a drive controller;
• a lens apparatus comprising a plurality of lenses configured to be adjusted to achieve variable focus;
• and
• an image sensor configured to generate an image signal based on the input light,
• wherein the dual prism apparatus comprises:
• 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 for outputting the reflected light toward the lens apparatus and the image sensor,
• wherein in response to the movement causing rotation of the first prism about the first rotation axis by a first angle and rotation of the second prism about the second rotation axis by a second angle, the drive controller is configured to:
• generate the first control signal to cause the first actuator to rotate the first prism in a third direction opposite the first reflected direction by a third angle;
• and
• generate the second control signal to cause the second actuator to rotate the second prism in a fourth direction opposite the second reflected direction by a fourth angle,
• wherein the third angle is half of the first angle, and
• wherein the fourth angle is half of the second angle.
