Display Motion Blur
In modern displays, motion blur is an unwanted artifact caused primarily by: # Retinal blur resulting from your eyes ''continuously'' tracking ''discrete'' movement. While your eyes move, the object you're tracking remains stationary throughout each frame, causing it to "smear". This does not happen in real life where both move continuously. # Slow pixel response times, which lead to visible ghosting or smearing. The faster the motion, the more pronounced the effect is. Cause Displays work by rapidly showing frames, each one slightly different from the previous, thereby creating the illusion of movement. Let's take a normal computer monitor with a resolution of 1920×1080 and a refreshrate of 60 Hz. If an object were to move across the display in 2 seconds, there would be 60×2 = 120 "steps", each one translated by 1920÷120 = 16 pixels. Your eyes, however, would not start and stop, over and over again to track the object, quickly moving the fovea to the "new" positio ...

Soccer Ball (blur)
A football or soccer ball is the ball used in the sport of association football. The ball's spherical shape, as well as its size, mass, and material composition, are specified by Law 2 of the Laws of the Game (association football), Laws of the Game maintained by the International Football Association Board. Additional, more stringent standards are specified by FIFA and other big governing bodies for the balls used in the competitions they sanction. Early footballs began as animal bladders or stomachs that would easily fall apart if kicked too much. Improvements became possible in the 19th century with the introduction of rubber and discoveries of vulcanization by Charles Goodyear. The modern 32-panel ball design was developed in 1962 by Eigil Nielsen (footballer, born 1918), Eigil Nielsen, and technological research continues to develop footballs with improved performance. The 32-panel ball design was soon joined by 24-panel balls as well as 42-panel balls, both of which improv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soap Opera Effect
The soap opera effect (SOE) is a complaint applied by some people against motion pictures with a high frame rate and/or shot on video as opposed to film stock. Images are denounced as "too realistic" or "too smooth" and therefore undesirable, especially for theatrical movies. Conversely, some people praise such characteristics, in general or especially for sports, news and video games due to superior ergonomics and fluidity onscreen. The opposite effect is the film look, felt by some as desirable enough to imitate through "filmization" or film emulation. Background This term is a reference to the distinctive appearance of most broadcast television soap operas or multicam sitcoms, which were typically shot using less expensive 50/60Hz video rather than pricier 24 FPS film used in theatrical movies or telecined for singlecam TV dramas. Differences in motion are most obvious in pans and other camera movement, while differences in color correction and other on-set dressing may ...

Telecine Judder
Telecine ( or ), or TK, is the process of transferring film into video and is performed in a color suite. The term is also used to refer to the equipment used in this post-production process. Telecine enables a motion picture, captured originally on film stock, to be viewed with standard video equipment, such as television sets, video cassette recorders (VCR), DVD, Blu-ray or computers. Initially, this allowed television broadcasters to produce programs using film, usually 16-mm stock, but transmit them in the same format, and quality, as other forms of television production. Furthermore, telecine allows film producers, television producers and film distributors working in the film industry to release their productions on video and allows producers to use video production equipment to complete their filmmaking projects. Within the film industry, it is also referred to as a ''TK'', ''TC'' having already been used to designate timecode. Motion picture film scanners are simila ...

Interlaced Video
Interlaced video (also known as interlaced scan) is a technique for doubling the perceived frame rate of a video display without consuming extra Bandwidth (signal processing), bandwidth. The interlaced signal contains two field (video), fields of a video frame captured consecutively. This enhances motion perception to the viewer, and reduces flicker (screen), flicker by taking advantage of the characteristics of the human visual system. This effectively doubles the time resolution (also called ''temporal resolution'') as compared to non-interlaced footage (for frame rates equal to field rates). Interlaced signals require a display that is natively capable of showing the individual fields in a sequential order. cathode-ray tube, CRT displays and ALiS plasma displays are made for displaying interlaced signals. Interlaced scan refers to one of two common methods for "painting" a video image on an electronic display screen (the other being progressive video, progressive scan) by sc ...

Laser TV
Laser color television (laser TV), or laser color video display, is a type of television that utilizes two 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 beams in a cathode ray tube, or by optically spreading and then modulating the laser and scanning a line at a time, the line itself being modulated in much the same way as with digital light processing (DLP). The special case of one ray reduces the system to a monochrome display as, for example, in black and white television. This principle applies to a direct view display as well as to a (front or rear) laser projector system. Laser TV technology began to appear in th ...

Input Lag
In computers, lag is delay ( latency) between the action of the user (input) and the reaction of the server supporting the task, which has to be sent back to the client. The player's ability to tolerate lag depends on the type of game being played. For instance, a strategy game or a turn-based game with a slow pace may have a high threshold or even be mostly unaffected by high lag. A game with twitch gameplay such as a first-person shooter or a fighting game with a considerably faster pace may require a significantly lower lag to provide satisfying gameplay. Lag is mostly measured in milliseconds (ms) and may be displayed in-game (sometimes called a lagometer). The most common causes of lag are expressed as ping time (or simply ''ping'') and the frame rate (fps). Generally a lag below 100 ms (10 hz or fps) is considered to be necessary for playability. The lowest ping physically possible for a connection between opposite points on Earth crossing half of the planet is 133 ms. ...
