Motion interpolationMotion interpolation, motion-compensated frame interpolation (MCFI), or frame generation, is a form of video processing in which intermediate film, video or animation frames are synthesized between existing ones by means of interpolation, in an attempt to make animation more fluid, to compensate for display motion blur, and for fake slow motion effects. In computer animation, interpolation can also be a natural automated process similar to inbetweening, where each frame depicts objects moving fluidly between key...
Liquid-crystal displayA liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers to display information. Liquid crystals do not emit light directly but instead use a backlight or reflector to produce images in color or monochrome. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images with low information content, which can be displayed or hidden: preset ...
Soap opera effectThe soap opera effect is a complaint against motion pictures with a high frame rate or shot on video as opposed to film stock. Images are denounced as "too realistic" or "too smooth" and therefore undesirable, especially for theatrical films. These complaints are less common outside of cinema, where some people praise or prefer higher frame rates (such as the increasingly common 50 and 60 FPS or higher), especially for sports, news and video games, due to superior ergonomics and fluidity onscreen. The opposite e...
Laser TVLaser color television (laser TV), or laser color video display, is a type of television that utilizes one or more individually modulated optical (laser) rays of different colors to produce a combined spot that is scanned and projected across the image plane by a polygon-mirror system or less effectively by optoelectronic means to produce a color-television display. The systems work either by scanning the entire picture a dot at a time and modulating the laser directly at high frequency, much like the electron b...
Refresh rateIn reference to terminology originating with cathode-ray tubes (CRTs), the refresh rate, also known as vertical refresh rate, vertical scan rate or vertical frequency, is the number of times per second that a raster-based display device displays a new image. This can be independent from frame rate, which describes how many images are stored or generated every second by the device driving the display. On CRT displays, higher refresh rates produce less flickering, thereby reducing eye strain. In other technologies...
Flat-panel displayA flat-panel display (FPD) is an electronic display used to display visual content such as text or images. It is present in consumer, medical, transportation, and industrial equipment. Flat-panel displays are thin, lightweight, provide better linearity and are capable of higher resolution and contrast than typical consumer-grade TVs from earlier eras. They are usually less than 10 centimetres (3.9 in) thick. While the highest resolution for consumer-grade CRT televisions is 1080i, many interactive flat panels in...
OLEDAn organic light-emitting diode (OLED), also known as organic electroluminescent (organic EL) diode, is a type of light-emitting diode (LED) in which the emissive electroluminescent layer is an organic compound film that emits light in response to an electric current. This organic layer is situated between two electrodes; typically, at least one of these electrodes is transparent. OLEDs are used to create digital displays in devices such as television screens, computer monitors, and portable systems such as smar...
Shutter speedIn photography, shutter speed or exposure time is the length of time that the film or digital sensor inside the camera is exposed to light (that is, when the camera's shutter is open) when taking a photograph. The amount of light that reaches the film or image sensor is proportional to the exposure time. 1⁄500 of a second will let half as much light in as 1⁄250. IntroductionThe camera's shutter speed, the lens's aperture or f-stop, and the scene's luminance together determine the amount of light that reaches...
RetinaThe retina (from Latin rete 'net'; pl. retinae or retinas) is the innermost, light-sensitive layer of tissue of the eye. The optics of the eye create a focused two-dimensional image of the visual world on the retina, which then processes that image within the retina and sends nerve impulses along the optic nerve to the visual cortex to create visual perception. The retina serves a function that is in many ways analogous to that of the film or image sensor in a camera. The neural retina consists of several layers...
Fovea centralisThe fovea centralis is a small, central pit composed of closely packed cones in the eye. It is located in the center of the macula lutea of the retina. The fovea is responsible for sharp central vision (also called foveal vision), which is necessary in humans for activities for which visual detail is of primary importance, such as reading and driving. The fovea is surrounded by the parafovea belt and the perifovea outer region. The parafovea is the intermediate belt, where the ganglion cell layer is composed of ...
Translation (geometry)In Euclidean geometry, a translation is a geometric transformation that moves every point of a figure, shape or space by the same distance in a given direction. A translation can also be interpreted as the addition of a constant vector to every point, or as shifting the origin of the coordinate system. In a Euclidean space, any translation is an isometry. A translation is an isometry that displaces the original figure according to a direction, a sense, and a length (vector). Translations preserve the direction a...
Visual artifactVisual artifacts (also artefacts) are anomalies apparent during visual representation as in digital graphics and other forms of imagery, especially photography and microscopy.*As an Amazon Associate I earn from qualifying purchases.
