An optical device able to change the direction of propagation of a light beam. The optical device allows a wide range of adjustment of the direction of the light beam, said optical device including, in the direction of propagation of the light beam, an overall divergent group of lenses and an overall convergent group of lenses. The overall divergent group of lenses contains, in the direction of propagation of the light beam, a fixed lens, and an optical module comprising at least one movable optical element able to change the direction of propagation of the light beam emerging from the overall divergent group of lenses.

A control apparatus includes a control unit for controlling a lens system of the photographing apparatus. When a distance from an object-side focus of the lens system to a photographed object changes from a to n×a due to moving of the photographing apparatus, the control unit changes a focal length of the lens system from f to n×f, and changes a distance from an image-side focus of the lens system to an image plane from b to n×b. The lens system has a zoom lens system and a focus lens system. By controlling the zoom lens system, the control unit changes the focal length of the lens system from f to n×f, and by controlling the focus lens system, the control unit changes the distance from the image-side focus of the lens system from b to n×b.

A system includes a high energy laser (HEL) configured to transmit a HEL beam aimed at a first location on an airborne target. The system also includes a beacon illuminator laser (BIL) configured to transmit a BIL beam aimed at a second location on the target, wherein the second location is offset from the first location. The system also includes at least one fast steering mirror (FSM) configured to steer the BIL beam to be spatially and angularly offset from the HEL beam. The system also includes at least one Coud path FSM configured to simultaneously receive both the HEL beam and the BIL beam and steer the HEL beam and the BIL beam to correct for atmospheric jitter of the HEL beam and the BIL beam while maintaining the offset of the BIL beam from the HEL beam.

An electronic device is disclosed. Moreover, various embodiment found through the disclosure are possible. The electronic device may include a camera module including an optical image stabilizer, a motion sensor, a processor electrically connected to the camera module and the motion sensor. The processor may be configured to obtain first motion information corresponding to shaking of the electronic device through the motion sensor, while at least partially obtaining an image frame, determine second motion information, which corresponds to motion of a lens or an image sensor included in the camera module, from the first motion information, using attribute information and a frequency pass filter of the optical image stabilizer, and perform digital image correction, based on the first motion information and the second motion information.

An accessory configured to be detachably mountable to an image pickup apparatus including a first mount portion including first bayonet claw portions, and first terminals, the accessory including a second mount portion including second bayonet claw portions configured to enable engagement with the first bayonet claw portions, and second terminals configured to enable contact with the first terminals, in which the second terminals are provided at positions that are different from positions of the second bayonet claw portions, and wherein, a half line that extends from a central axis of the second mount portion and passes through a second terminal that determines whether an optical apparatus is mounted on the image pickup apparatus or not, passes through a predetermined second bayonet claw portion.

A camera includes a lens-camera communication controller and an adapter-camera communication controller. The camera-lens communication channel includes a first data communication channel used during a data communication and a first notification channel used for a notification of a timing of a communication via the first data communication channel. The camera-adapter communication channel includes a second data communication channel used during the data communication and a second notification channel used for a notification of a timing of a communication via the second data communication channel.

The present disclosure relates to a projector, a projection method, an image processing system, and a method that make it possible to realize hand shake correction. A projection imaging apparatus includes a geometric correction section, a corresponding point detection section, a posture estimation section, a screen reconfiguration section, a projector, and a camera. An input video is input to the geometric correction section. The projector houses an IMU (inertial measurement apparatus) and a delay compensation circuit. For example, the present disclosure can be applied to the projection imaging apparatus that projects an image by using the projector, captures the image projected by the projector, and performs correction.

An optical motion detecting device for a flight vehicle includes a base, an optical motion sensor and an operating processor. The optical motion sensor is disposed on the base and adapted to capture a plurality of frames. The operating processor is electrically connected with the optical motion sensor.
