| video waveform | <microscopy> The display of the (composite) video signal onto a cathode-ray oscilloscope triggered by the V- or H-sync pulse. The amplitudes and waveforms, as well as precision of timing, of the signal components are made visible. (05 Aug 1998) |

| waveform monitor | <microscopy> A cathode-ray oscilloscope that can conveniently display the video signal. See: video waveform. (05 Aug 1998) |

| Allen video enhanced contrast | <procedure> A method for enhancing microscopic images pioneered by R D Allen. The digitised image has the background (an out of focus image of the same microscopic field with comparable unevenness of illumination etc.) subtracted and the contrast expanded to utilise the potential contrast range. Interestingly, it is possible to produce images of objects that are below the theoretical limit of resolution microtubules for example. (18 Nov 1997) |
| video-assisted thoracic surgery | A less morbid alternative to "open" thoracotomy that employs cameras, optic systems, percutaneous stapling devices, and assorted endoscopic graspers, retractors, and forceps. Also called video thoracoscopic surgery, it can be selectively applied to various pulmonary, pleural, and pericardial lesions. (05 Mar 2000) |
| video games | A form of interactive entertainment in which the player controls electronically generated images that appear on a video display screen. This includes video games played in the home on special machines or home computers, and those played in arcades. (12 Dec 1998) |
| video microscopy | <technique> Microscopy that takes advantage of video as an imaging, image processing, analysing, or controlling device. (05 Aug 1998) |
| video recording | The storing or preserving of video signals for television to be played back later via a transmitter or receiver. Recordings may be made on magnetic tape or discs (videodisc recording). (12 Dec 1998) |
| microscopy, video | Microscopy in which television cameras are used to brighten magnified images that are otherwise too dark to be seen with the naked eye. It is used frequently in telepathology. (12 Dec 1998) |
