A Flip video camera, formerly manufactured by Cisco. A 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 ...
Skycam HD at an ESPN on ABC–broadcast University of California, Berkeley football game.. While "SkyCam" is a registered trademark, the term "Skycam" is often used generically for cable-suspended camera system, and competing systems like CableCam (invented by Jim Rodnunsky but also a subsidiary of Kroenke Sports & Entertainment, LLC), Spidercam and Robycam 3D.
Modern digital television camera with a DIGI SUPER 86II xs lens from Canon. A professional video camera (often called a television camera even though its use has spread beyond television) is a high-end device for creating electronic moving images (as opposed to a movie camera, that earlier recorded the images on film).
These cameras do not require a video capture card because they work using a digital signal which can be saved directly to a computer. The signal is compressed 5:1, but DVD quality can be achieved with more compression (MPEG-2 is standard for DVD-video, and has a higher compression ratio than 5:1, with a slightly lower video quality than 5:1 at best, and is adjustable for the amount of space to ...
Old video camera viewfinder cutway; note the miniature CRT An Olympus PEN E-PL5 mounted with an external EVF unit: the Olympus VF-4 EVF of Panasonic Lumix DMC-G85/G80 with 2,360,000 dots. An electronic viewfinder ( EVF ) is a camera viewfinder where the image captured by the lens is displayed on a small screen (usually LCD or OLED ) which the ...
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation about the optical axis ().

Final results depend on the readout speed of the sensor and the nature of the scene being filmed; as a rule of thumb, higher-end cinema cameras will have faster readout speeds and therefore milder rolling shutter artifacts than low-end cameras. Images and video that suffer from rolling shutter distortion can be improved by algorithms that do ...
Some long-wave cameras require their detector to be cryogenically cooled, typically for several minutes before use, although some moderately sensitive infrared cameras do not require this. Many thermal imagers, including some forward-looking infrared cameras (such as some LWIR enhanced vision systems (EVS)) are also uncooled.
