Embodiments of the present disclosure include an apparatus with a camera. A shutter is positioned horizontally in front of the lens of the camera. The shutter is configured to move in front of a lens of the camera and is further configured to move orthogonally to the horizontal axis so as to at least partially obscure the lens of first camera in a closed shutter position. The apparatus further includes a motor positioned horizontally behind the front of the lens of the camera. The motor is configured to move the shutter orthogonally to the horizontal axis between the closed shutter position and an open shutter position.

An X-ray imaging system includes an X-ray detector; a plurality of X-ray sources configured to illuminate the detector from different perspectives; a shutter in a transmission plane between each X-ray source controlling transmission of X-rays from each X-ray source to the detector; and a processor configured to receive and process X-ray data from the detector. The shutter may be configured to illuminate the detector alternately with each X-ray source. The processor may determine 3D information about an object from the processed X-ray data. Also provided are methods for processing X-ray data and different embodiments of shutters to alternately illuminate X-ray detectors.

An exposure method in panoramic photo shooting to resolve a problem that luminance of a composite picture in panoramic photo shooting is not smooth, where the method includes obtaining, by a terminal device, luminance values respectively corresponding to M pictures shot in advance and a luminance value of a current environment in which shooting is to be performed, where M is a positive integer, obtaining, by the terminal device by means of calculation according to the luminance values respectively corresponding to the M pictures shot in advance and the luminance value of the current environment in which shooting is to be performed, a luminance value of a picture to be shot, and performing, by the terminal device, exposure according to the luminance value of the picture to be shot.

An image-capturing apparatus includes an insertion and removal unit configured to insert and remove the infrared light cut filter to and from an optical path of the image-capturing optical system. An adjustment command capable of describing a brightness value of a brightness of the subject and a delay time for determining the brightness and capable of separately describing the brightness value in each of the cases where the infrared light cut filter is inserted into or removed from the optical path is received from the external apparatus via a network. A determination is made as to whether a content of an adjustment command matches a content stored in advance, and the brightness value and the delay time included in the adjustment command are converted into values that can be set in a case where the determination unit determines that the content of the adjustment command matches the content stored.
