Field / frame integration
| Глоссарий терминов по видеокамерам |
Two different pixel readout techniques in ccds designed for interlaced output. refers to the total integration time, field duration (16.6 ms ntsc/eia or 20 ms pal/ccir) or frame duration (33.3 ms ntsc/eia or 40 ms pal/ccir). both modes give the same sensitivity. in field integration, pixels of two adjacent lines are read out together as one. the full ccd is read every field, achieving higher picture refresh rate but lower vertical resolution. mostly used in current applications to achieve optimum capture of movement. adjacent lines are combined differently for odd (1+2, 3+4, . . .) and even field (2+3, 4+5, . . .) outputs. in frame integration, pixels are read out separately. the complete ccd is read after two fields. full vertical resolution is achieved. progressive scan ccds operate only in frame integration.

- Term used to describe an image sensor that gathers its data by first processing the odd lines and then the even lines. see also progressive scan for the other (preferred) method.

Sensitivity, английский
- Change in the response of a measuring instrument divided by the corresponding change in the stimulus (1)
- The ratio of the output of an instrument to the input (i.e. -gain).
- Defines the smallest signal detectable in the presence of systems noise
- In television, a factor expressing the incident illumination upon a specified scene required to produce a specified picture signal at the output terminals of a television camera.

- A measure of the amount of light required to provide a standard video signal. sensitivity values are stated in lux (see lux) or foot-candles.
- Lens iris aperture required to provide a video output signal of standard level at a specified light input. in general, sensitivity is measured using an 89.9% reflectance grey scale chart illuminated by a 3200? k illuminance at 2000 lux (color camera) or 400 lux (b/w camera), for a video output level of 100%.
- 1. the fact of being able to detect and respond to an outside stimulus 2. the rate of positive responses in a test from persons with a specific disease. a high rate of sensitivity means a low rate of people being incorrectly classed as negative. compare specificity

- The sensitivity of classification rule is a measure of its ability to correctly classify observations into a particular category. it is defined to be the ratio of the number of true positives to the number of positives in a test set. this value is usually inversely related to the specificity of the test for a given set of data and a particular classification rule. note that this measure is different from the positive predictive value of a rule, which is a measure of the probability that a positive is a true positive. if multiple classification categories exist, each category will have its own sensitivity, specificity, and positive predictive value. see also: positive predictive value, specificity.
- Чувствительность: a) различие в концентрации аналита, соответствующее наименьшему обнару-живаемому различию в реакции метода. представляется наклоном калибровоч-ной кривой. иногда ошибочно используется для обозначения предела обнаружения. b) частота истинно положительных результатов, полученных при испытании проб, в которых, насколько известно, содержится аналит [55]. c) отношение изменения показаний измерительного прибора к соответствую-щему изменению измеряемой величины. измеряемой величиной может быть, например, количество исследуемого вещества, содержащееся в пробе.
- Чувствительность. в сенсорном анализе — способность различать, идентифицировать и/или дифференцировать (качественно и/или количественно) один или более раздражителей с помощью органов чувств (предварительный стандарт мос, 12). в аналитической химии — чувствительность метода, которая (для простого-метода)- характеризуется наклоном калибровочной кривой, т. е. является дифференциалом измеряемой величины по отношению к концентрации dx/dc. чувствительность не следует путать с наименьшим количеством или наиболее низкой концентрацией, которые можно обнаружить с помощью данного метода; правильный термин для обозначения этого понятия — предел чувствительности (см. limit of detection).
- The output of a microphone in volts for a given input in sound pressure level. sensitivity can also mean the sound pressure level (spl) a loudspeaker produces at one meter when driven with one watt of pink noise.
- The degree of confidentiality of an e-mail message or calendar item, ranging from normal to confidential.
- The significance level that must be reached before a notification is sent.
- Чувствительность:
- Measure of a sensor’s ability to detect small signals. see resolution.
- Ability of a sensor or system to distinguish a signal or indication from background noise. see also probability of detection.
- Ability of a sensor or system to distinguish a signal or indication from background noise. see also probability of detection. si (international system of units): international measurement system in which the following seven
- (1) performance characteristic of a penetrant system, of a developer, or of an entire penetrant process that provides a relative measure of the ability to detect discontinuities. (2) enumerated level of performance of a penetrant system determined by applying standardized processing procedures on reference standards with known defects. (3) ability of a sensor or system to distinguish a signal or indication from background noise. compare probability of detection.

Resolution, английский
- The smallest change in the parameter being measured that causes a detectable change in the output of the instrument.
- Разрешение
- Defines the smallest resolvable object in the target plane at a given range-to-target, atmospheric condition and target signal level ability of a telescope to differentiate between two objects in the sky which are separated by a small angular distance
- The measure of the fine detail that can be seen in an image. for analog systems this is typically measured in television lines or tvl. the higher the tvl rating, the higher the resolution.
- Refers to the degree of detail of an image. it is usually measured in dots per inch (dpi) or lines per inch (lpi). a high resolution gives a high quality image and vice versa.
- The quality of any digital image, whether printed or displayed on a screen, depends in part on its resolution—the number of pixels used to create the image. more and smaller pixels adds detail and sharpens edges. l optical is an absolute number that the camera`s image sensor can physically record. l interpolated adds pixels to the image using complex software algorithms to determine what color they should be. it is important to note that interpolation doesn`t add any new information to the image it just makes it bigger! camera makers often specify the resolution as: qvga (320 x 240), vga (640 x 480), svga (800 x 600), xga (1024 x 768) or uxga (1600 x 1200)
- A measure of picture resolving capabilities of a television system determined primarily by bandwidth, scan rates and aspect ratio. relates to fineness of details perceived.
- The ability to distinguish fine detail or resolve information within an image.
- Refers to the number of pixels, both horizontally and vertically, used to either capture or display an image. the higher the resolution, the finer the image detail will be.
- The quality of any digital image, whether printed or displayed on a screen, depends on its resolution, or the number of pixels used to create the image. more, smaller pixels add detail and sharpen the edges.

- A measure of the fineness of detail in an image or text, usually as produced by a monitor or printer.
- Loosely speaking, the quality of an image. when printing or working with images, the resolution is usually measured in dots per inch (dpi) - the more dots per inch, the higher the quality of the image but the larger the file needed to store it. in windows, the screen resolution is how many- pixels- fit on the desktop, the most popular being 800 x 600 and 1024 x 768 - the former makes images, icons etc look bigger, but the latter means you can fit more of them on the screen.
