A high-speed camera is a device capable of capturing moving images with exposures of less than 1 / 1 000 second or frame rates in excess of 250 frames per second. [1] It is used for recording fast-moving objects as photographic images onto a storage medium. After recording, the images stored on the medium can be played back in slow motion.
Muybridge's photographic sequence of a race horse galloping, first published in 1878. High-speed photography is the science of taking pictures of very fast phenomena. In 1948, the Society of Motion Picture and Television Engineers (SMPTE) defined high-speed photography as any set of photographs captured by a camera capable of 69 frames per second or greater, and of at least three consecutive ...
On the left there are two progressive scan images. In the middle there are two interlaced images and on the right there are two images with line doublers. The original resolutions are above and the ones with spatial anti-aliasing are below. The interlaced images use half the bandwidth of the progressive ones.
The lifetime risk of developing ALS is 1:350 for European men and 1:400 for European women. Men have a higher risk mainly because spinal-onset ALS is more common in men than women. [63] The number of those with ALS in the United States in 2015 was 5.2 people per 100,000, and was higher in whites, males, and people over 60 years old. [124]
Last April, Goodfriend was diagnosed with ALS, or Amyotrophic Lateral Sclerosis, a disease that attacks the nervous system and robs people of their muscle control. The 83-year-old widow spent ...
Interlaced scan refers to one of two common methods for "painting" a video image on an electronic display screen (the other being progressive scan) by scanning or displaying each line or row of pixels. This technique uses two fields to create a frame. One field contains all odd-numbered lines in the image; the other contains all even-numbered ...
Last month the ALS Ice Bucket Challenge celebrated its 10th anniversary. The fundraising idea was the brainchild of both the late Pete Frates — a Massachusetts native, lifelong Boston Red Sox ...
The Panasonic Lumix DMC-GH2 is capable of recording 40 still images per second in burst mode, at a slightly reduced resolution. In March 2014, Nikon claims its Nikon 1 V3 mirrorless interchangeable-lens camera has the world's fastest burst mode of 20fps Auto Focus tracking and 60fps at the first shot autofocus, both in 18.4MP full resolution ...
