Video cameraA video camera is an optical instrument that captures videos, as opposed to a movie camera, which records images on film. Video cameras were initially developed for the television industry but have since become widely used for a variety of other purposes. Video cameras are used primarily in two modes. The first, characteristic of much early broadcasting, is live television, where the camera feeds real time images directly to a screen for immediate observation.
CameraA camera is an instrument used to capture and store images and videos, either digitally via an electronic image sensor, or chemically via a light-sensitive material such as photographic film. As a pivotal technology in the fields of photography and videography, cameras have played a significant role in the progression of visual arts, media, entertainment, surveillance, and scientific research.
Panning (camera)In cinematography and photography, panning means swivelling a still or video camera horizontally from a fixed position. This motion is similar to the motion of a person when they turn their head on their neck from left to right. In the resulting image, the view seems to "pass by" the spectator as new material appears on one side of the screen and exits from the other, although perspective lines reveal that the entire image is seen from a fixed point of view.
Image-stabilized binocularsImage-stabilized binoculars are binoculars that have a mechanism for decreasing the apparent motion of the view due to binocular movement. Such binoculars are designed to minimize image shaking in hand-held applications. Higher-power binoculars magnify the image more, but the image shift is also increased. This means that even minor hand movements can cause huge image shifts.
Digital cameraA digital camera, also called a digicam, is a camera that uses digital storage to capture images. Most cameras produced since the start of the 21st century are digital, largely replacing cameras that captured images on photographic film or film stock. Many digital cameras are now integrated into mobile devices such as smartphones. However, high-end dedicated digital cameras are still commonly used by professionals.Motion blur (media)Motion blur is the apparent streaking of moving objects in a photograph or a sequence of frames, such as a film or animation. It results when the image being recorded changes during the recording of a single exposure, due to rapid movement or long exposure. Usages / Effects of motion blurPhotographyWhen a camera creates an image, that image does not represent a single instant of time.
Exposure (photography)In photography, exposure is the amount of light per unit area reaching a frame of photographic film or the surface of an electronic image sensor. It is determined by exposure time, lens f-number, and scene luminance. Exposure is measured in units of lux-seconds (symbol lx⋅s), and can be computed from exposure value (EV) and scene luminance in a specified region. An "exposure" is a single shutter cycle.
MotionIn physics, motion is the change in position of an object or fluid with respect to a reference frame over a given time.
Aircraft principal axesAn aircraft in flight is free to rotate in three dimensions: yaw, nose left or right about an axis running up and down; pitch, nose up or down about an axis running from wing to wing; and roll, rotation about an axis running from nose to tail. The yaw, pitch, and roll axes are alternatively designated as vertical, lateral (or transverse), and longitudinal respectively. These axes move with the vehicle and rotate relative to the Earth along with the craft.
Tilt (camera)Tilting is a cinematographic technique in which the camera stays in a fixed position but rotates up/down in a verticalplane. Tilting the camera results in a motion similar to someone raising or lowering their head to look up or down. It is distinguished from panning in which the camera is horizontally pivoted left or right. Pan and tilt can be used simultaneously.
TelescopeA telescope is a device used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. Originally, it was an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects – an optical telescope. Nowadays, the word "telescope" is defined as a wide range of instruments capable of detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors.
