e) A television picture is produced by scanning the TV screen with an electron beam. Two fields are required to make a complete picture, which is called a frame. To keep two sequences playing at the same rate (in sync). This mounting is defined by a 1-inch (2.54 cm) diameter hole with 32 TPI (turns/threads per inch), female on the camera side, male on the lens side, and a back flange-to-CCD distance of 17.526 mm (0.69 inches).
It is not clear on what evidence he has asked people to do this. The total area, occupied by the television picture, which is scanned while the picture signal is not blanked. a) An electronic signal where every different value from the real-life excitation (sound, light) has a different value of binary combinations (words) that represent the analog signal. A visual perception that humans correspond to the categories called red, green, blue and others. A device upon which a camera can be mounted that allows movement in both the azimuth (pan) and in the vertical plane (tilt).[7]. (Luminance is the recommended name for the photo-electric quantity which has also been called brightness.). Maintaining two or more scanning processes in phase. When improperly applied can result in loss of picture information in very bright or very dark areas; Also used in switchers to set the cutoff point for mixing video signals. The electronic representation of a sequence of images, depicting either stationary or moving scenes. An electronic limit usually imposed in cameras to avoid overly bright or dark signals.
A transient of short duration, comprising part of a pulse, during which the amplitude considerably exceeds the average amplitude of the pulse.
Audio is supported at rates from 32 kbit/s to 384 kbit/s for up to two stereo channels. The details that can be distinguished on the television screen. VBR compression can take better advantage of the overall available bandwidth of a video transmission or DVD player by allocating the available bits intelligently to the difficult parts of a sequence. To save this word, you'll need to log in.
Saturation is directly related to the amplitude of the chrominance signal. The level of the peaks of a synchronizing signal. A signal which moves through a continuous range of settings or levels. A generalized use class aspect that specifies the level of motion you anticipate in a scene of interest. The science of analysis. The range of sensor-to-lens distance for which the image formed by the lens is clearly focused. You can click words for definitions.
Definition and synonyms of video conference from the online English dictionary from Macmillan Education. The direct light that falls on an object. Our. Related definition is - connected by reason of an established or discoverable relation. Cable TV … A device for generating a synchronizing signal. See also, the Target Size topic for video quality requirements considerations.[3]. Sometimes, clipping is performed prior to modulation, and sometimes to limit the signal, so it will not exceed a predetermined level.[1]. Related Words. Most commonly, video hue is influenced by a camera's white balance or scene lighting. Video uses higher frequency than audio, thus requires a wider bandwidth.[2].
Good luck! How to use related in a sentence. For MPEG-2 video, for example, this means that “easier” sequences (that is, with no motion) can compress to very small sizes, whereas “hard” sequences (with lots of motion and scene cuts) can compress to much larger sizes. This comes just three days after he was executed in Terre Haute. The thesaurus contains more than 145,800 unique entries from three top sources: Collins Thesaurus of the English Language - Complete and Unabridged, The American Heritage Roget's Thesaurus, and WordNet.
It reduces the light entering a lens, thus forcing the iris to open to its maximum. When finished, click Answer to see the results. You can unsubscribe at any time. For the most part, the larger number of pixels, the better the quality of the picture. The signal used for the synchronizing of scanning specified in EIA Standards RS-170, RS-330, RS-343, or subsequent issues.

Raw files are so named because they are not yet processed and therefore are not ready to be printed or edited with a bitmap graphics editor.
Luminous intensity of any surface in a given direction per unit of projected area of the surface viewed from that direction. Any form of signal that carries information in the form of variable physical values, such as amplitude or frequency modulation. VESA's mission is to promote and develop timely, relevant, open display and display interface standards, ensuring interoperability, and encouraging innovation and market growth. This is the British English definition of video conference.View American English definition of video conference. The MP for Crewe and Nantwich, Dr Kieran Mullan, has criticised the leader of Cheshire East Council over a social media video. Among these are the limited frequency response of magnetic tapes and signal losses associated with electronic circuitry employed in the recording process.
Abbreviation of megabits per second. A circuit for automatically controlling amplifier gain in order to maintain a constant output voltage with a varying input voltage within a predetermined range of input-to-output variation. Device used to recover the component signals from a composite (encoded) source. ), so consider that your search query for words like term may be a bit ambiguous to the engine in that sense, and the related terms that are returned may reflect this. The difference between the maximum acceptable signal level and the minimum acceptable signal level. This tool helps you find words that are related to a specific word or phrase. It has a wide range of application in safety and security to examine video for specific data, behavior, objects or attitude. CCDs are the most commonly found type of image sensor in consumer camcorders and video cameras.
The higher the definition of an image, the greater the number of details [that can be discerned by the human eye or displayed]. [5], A device that intensifies low light-level images to light levels that can be seen with the human eye or can be detected by a video camera. [3], The picture signal. Amplitude variations in the output voltage of a power supply caused by insufficient filtering. To provide for a linear transfer characteristic from input to output device. The process that established a fixed level for the picture level at the beginning of each scanning line.
In color television, that part of the signal wave which has major control of the brightness values of the picture, whether displayed in color or in monochrome.
