Interlacing was invented as a way to reduce flicker in early mechanical and CRT video displays without increasing the number of complete frames per second. When displaying a natively progressive broadcast or recorded signal, the result is optimum spatial resolution of both the stationary and moving parts of the image. In progressive scan systems, each refresh period updates all scan lines in each frame in sequence. The minimum frame rate to achieve a comfortable illusion of a moving image is about sixteen frames per second. Film is shot at the slower frame rate of 24 frames per second, which slightly complicates the process of transferring a cinematic motion picture to video. PAL standards (Europe, Asia, Australia, etc.) and SECAM (France, Russia, parts of Africa etc.) specify 25 frame/s, while NTSC standards (USA, Canada, Japan, etc.) specify 29.97 frame/s. ![]() Characteristics of video streams Number of frames per second įrame rate, the number of still pictures per unit of time of video, ranges from six or eight frames per second ( frame/s) for old mechanical cameras to 120 or more frames per second for new professional cameras. ![]() Since 2013, the usage of digital cameras in Hollywood has surpassed use of film cameras. ![]() The development of high-resolution video cameras with improved dynamic range and color gamuts, along with the introduction of high-dynamic-range digital intermediate data formats with improved color depth, has caused digital video technology to converge with film technology. The advent of digital broadcasting and the subsequent digital television transition is in the process of relegating analog video to the status of a legacy technology in most parts of the world. Advances in computer technology allows even inexpensive personal computers and smartphones to capture, store, edit and transmit digital video, further reducing the cost of video production, allowing program-makers and broadcasters to move to tapeless production. After the invention of the DVD in 1997, and later the Blu-ray Disc in 2006, sales of videotape and recording equipment plummeted. Enter in your name and see where you rank on the leaderboard highlighted in yellow.See also: Digital television and Video coding formatĭigital video is capable of higher quality and, eventually, much lower cost than earlier analog technology. The game ends once the entire game board is filled up with balls. Instead, you will be rewarded with yet another move before new three balls. With every move computer adds three new balls to the board, however new balls will not be added to the game board after a line removal. You can only move a ball if a free path exists between the current location and the destination selected. ![]() To move a ball, select it first by clicking on it, and then click on a destination square. To remove balls, arrange at least five same color balls to lines (horizontal, vertical or diagonal). The more balls you remove the more points you earn. Points are earned every time you remove balls from the board. Player’s objective is to earn the highest score (no limit). Game starts with several randomly selected balls placed on the board. To see the best players in your country, go to the leaderboard and filter by country.Ĭolor Lines game board has 81 (9×9) cells (squares). Compete with the best color lines game players around the world.
