Still Video Camera
A still video camera (SVC) is a type of electronic camera that takes still images and stores them as single frames of video. They peaked in popularity in the late 1980s and can be seen as the predecessor to the digital camera. However, unlike the latter, the image storage in such cameras is based on analog technology, rather than as a digital file. Design The most common design has an image sensor and basic processing hardware similar to that of a consumer camcorder designed for analog television using the appropriate regional format ( NTSC, PAL, or SECAM). However, instead of storing consecutive interlaced fields on tape to form a moving image, a single field or frame (combined from two fields) is extracted from the output video signal and saved on a rotating magnetic disk, typically a standard Video Floppy. During playback, the disk is spun at the frame rate of the video system with the field or frame being read repeatedly. This produces a conventional analog video signal th ...

Sony Mavica
Mavica (''Magnetic Video Camera'') is a discontinued brand of Sony cameras which use removable disks as the main recording medium. On August 25th 1981, Sony unveiled a prototype of the Sony Mavica as the world's first electronic still video camera. As with all Mavica cameras until the early 1990s (including later models sold commercially) this first model was not digital. Its CCD sensor produced an analog video signal in the NTSC format at a resolution of pixels. Mavipak 2.0" disks (later adopted industry-wide as the Video Floppy and labelled "VF") were used to write 50 still frames onto tracks on disk. The pictures could be shown on a television screen, using a "special playback viewer unit" plugged into the television set. During the late 1990s and early 2000s, Sony reused the Mavica name for a number of digital (rather than analog) cameras that used standard 3.5" floppy disk or 8 cm CD-R media for storage. Original analog Mavica models The initial prototype demonstrated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frame Rate
Frame rate (expressed in or FPS) is the frequency (rate) at which consecutive images ( frames) are captured or displayed. The term applies equally to film and video cameras, computer graphics, and motion capture systems. Frame rate may also be called the , and be expressed in hertz. Frame rate in electronic camera specifications may refer to the maximal possible rate, where, in practice, other settings (such as exposure time) may reduce the frequency to a lower number. Human vision The temporal sensitivity and resolution of human vision varies depending on the type and characteristics of visual stimulus, and it differs between individuals. The human visual system can process 10 to 12 images per second and perceive them individually, while higher rates are perceived as motion. Modulated light (such as a computer display) is perceived as stable by the majority of participants in studies when the rate is higher than 50 Hz. This perception of modulated light as steady is kn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polaroid Corporation
Polaroid is an American company best known for its instant film and cameras. The company was founded in 1937 by Edwin H. Land, to exploit the use of its Polaroid polarizing polymer. Land ran the company until 1981. Its peak employment was 21,000 in 1978, and its peak revenue was $3 billion in 1991. When the original Polaroid Corporation was declared bankrupt in 2001, its brand and assets were sold off. The "new" Polaroid formed as a result, itself declared bankruptcy in 2008, resulting in a further sale to Polish billionaire Wiaczesław Smołokowski. In May 2017, the brand and intellectual property of Polaroid Corporation were acquired by the largest shareholder of the Impossible Project, which had originally started out in 2008 by producing new instant films for Polaroid cameras. The Impossible Project was renamed Polaroid Originals in September 2017, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charge-coupled Device
A charge-coupled device (CCD) is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a major technology used in digital imaging. In a CCD image sensor, pixels are represented by p-doped metal–oxide–semiconductor (MOS) capacitors. These MOS capacitors, the basic building blocks of a CCD, are biased above the threshold for inversion when image acquisition begins, allowing the conversion of incoming photons into electron charges at the semiconductor-oxide interface; the CCD is then used to read out these charges. Although CCDs are not the only technology to allow for light detection, CCD image sensors are widely used in professional, medical, and scientific applications where high-quality image data are required. In applications with less exacting quality demands, such as consumer and professional digital cameras, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Akio Morita
was a Japanese businessman and co-founder of Sony along with Masaru Ibuka. Early life Akio Morita was born in Nagoya. Morita's family was involved in sake, miso and soy sauce production in the village of Kosugaya (currently a part of Tokoname City) on the western coast of Chita Peninsula in Aichi Prefecture since 1665. He was the oldest of four siblings and his father Kyuzaemon trained him as a child to take over the family business. Akio, however, found his true calling in mathematics and physics, and in 1944 he graduated from Osaka Imperial University with a degree in physics. He was later commissioned as a sub-lieutenant in the Imperial Japanese Navy, and served in World War II. During his service, Morita met his future business partner Masaru Ibuka in the Navy's Wartime Research Committee. Sony In September 1945, Ibuka founded a radio repair shop in the bombed out Shirokiya Department Store in Nihonbashi, Tokyo. Morita saw a newspaper article about Ibuka's new venture and, ...

Video Capture Card
Video capture is the process of converting an analog video signal—such as that produced by a video camera, DVD player, or television tuner—to digital video and sending it to local storage or to external circuitry. The resulting digital data are referred to as a ''digital video stream'', or more often, simply ''video stream''. Depending on the application, a video stream may be recorded as computer files, or sent to a video display, or both. Devices Special electronic circuitry is required to capture video from analog video sources. At the system level this function is typically performed by a dedicated video capture device. Such devices typically employ integrated circuit video decoders to convert incoming video signals to a standard digital video format, and additional circuitry to convey the resulting digital video to local storage or to circuitry outside the video capture device, or both. Depending on the device, the resulting video stream may be conveyed to external circ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
