Lithium-ion
A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. It is the predominant battery type used in portable consumer electronics and electric vehicles. It also sees significant use for grid-scale energy storage and military and aerospace applications. Compared to other rechargeable battery technologies, Li-ion batteries have high energy densities, low self-discharge, and no memory effect (although a small memory effect reported in LFP cells has been traced to poorly made cells). Chemistry, performance, cost and safety characteristics vary across types of lithium-ion batteries. Most commercial Li-ion cells use intercalation compounds as the active materials. The anode or negative electrode is usually graphite, although silicon-carbon is also being increasingly used. Cells can be manufactured to prioritize either energy or power density. Handheld electronics mostly use lithium polymer batteries (w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyber-shot Cameras
Cyber-shot is Sony's line of point-and-shoot digital cameras introduced in 1996. Cyber-shot model names use a DSC prefix, which is an initialism for "Digital Still Camera". Many Cyber-shot models feature Carl Zeiss trademarked lenses, while others use Sony, or Sony G lenses. All Cyber-shot cameras accept Sony's proprietary Memory Stick or Memory Stick PRO Duo flash memory. Select models have also supported CompactFlash. Current Cyber-shot cameras support Memory Stick PRO Duo, SD, SDHC, and SDXC. From 2006 to 2009, Sony Ericsson used the Cyber-shot brand in a line of mobile phones. Models The current lineup consists of: * R and RX series – state-of-the-art, large-sensor compact cameras ** DSC-RX100/DSC-RX100 II/III/IV/V/VI/VII – pocketable camera with the largest 1" sensor of all cameras of its size ** DSC-RX10/DSC-RX10 II — zoom lens 1" 24-200mm equivalent 35mm bridge camera with constant widest aperture F2.8 ** DSC-RX10 III/DSC-RX10 IV — zoom lens 1" 24-600mm eq ...

AVCHD
AVCHD (Advanced Video Coding High Definition) is a file-based format for the digital recording and playback of high-definition video. It is H.264 and Dolby AC-3 packaged into the MPEG transport stream, with a set of constraints designed around the camcorders. Developed jointly by Sony and Panasonic, the format was introduced in 2006 primarily for use in high definition consumer camcorders. Related specifications include the professional variants AVCCAM and NXCAM. Favorable comparisons of AVCHD against HDV and XDCAM EX solidified perception of AVCHD as a format acceptable for professional use. Both Panasonic and Sony released the first consumer AVCHD camcorders in spring of 2007. Panasonic released the first AVCHD camcorder aimed at the professional market in 2008, though it was nothing more than the (by then discontinued) FLASH card consumer model rebadged with a different model number. In 2011 the AVCHD specification was amended to include 1080-line 50-frame/s and 60-frame/s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Full HD
1080p (1920×1080 progressively displayed pixels; also known as Full HD or FHD, and BT.709) is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; the ''p'' stands for progressive scan, ''i.e.'' non-interlaced. The term usually assumes a widescreen aspect ratio of 16:9, implying a resolution of 2.1 megapixels. It is often marketed as Full HD or FHD, to contrast 1080p with 720p resolution screens. Although 1080p is sometimes informally referred to as 2K, these terms reflect two distinct technical standards, with differences including resolution and aspect ratio. 1080p video signals are supported by ATSC standards in the United States and DVB standards in Europe. Applications of the 1080p standard include television broadcasts, Blu-ray Discs, smartphones, Internet content such as YouTube videos and Netflix TV shows and movies, consumer-grade televisions and projectors, ...

Optical Resolution
Optical resolution describes the ability of an imaging system to resolve detail, in the object that is being imaged. An imaging system may have many individual components, including one or more lenses, and/or recording and display components. Each of these contributes (given suitable design, and adequate alignment) to the optical resolution of the system; the environment in which the imaging is done often is a further important factor. Lateral resolution Resolution depends on the distance between two distinguishable radiating points. The sections below describe the theoretical estimates of resolution, but the real values may differ. The results below are based on mathematical models of Airy discs, which assumes an adequate level of contrast. In low-contrast systems, the resolution may be much lower than predicted by the theory outlined below. Real optical systems are complex, and practical difficulties often increase the distance between distinguishable point sources. The ...

Megapixel
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest point in an all points addressable display device. In most digital display devices, pixels are the smallest element that can be manipulated through software. Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black. In some contexts (such as descriptions of camera sensors), ''pixel'' refers to a single scalar element of a multi-component representation (called a ''photosite'' in the camera sensor context, although ''sensel'' is sometimes used), while in yet other contexts (like MRI) it may refer to a set of component intensities for a spatial position.

Wide-angle Lens
In photography and cinematography, a wide-angle lens refers to a lens whose focal length is substantially smaller than the focal length of a normal lens for a given film plane. This type of lens allows more of the scene to be included in the photograph, which is useful in architectural, interior and landscape photography where the photographer may not be able to move farther from the scene to photograph it. Another use is where the photographer wishes to emphasise the difference in size or distance between objects in the foreground and the background; nearby objects appear very large and objects at a moderate distance appear small and far away. This exaggeration of relative size can be used to make foreground objects more prominent and striking, while capturing expansive backgrounds. A wide angle lens is also one that projects a substantially larger image circle than would be typical for a standard design lens of the same focal length. This large image circle enables either lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hyperzoom
A superzoom or ultrazoom lens is a type of photographic zoom lens with unconventionally large focal length factors, typically ranging from wide angle to extreme long lens focal lengths in one lens. There is no clear definition of a superzoom lens, but the name generally covers lenses that have a range well above the 3× or 4× of a standard zoom lens, with lenses being 10×, 12×, 18×, or above considered superzoom. Due to trade-offs in the optical design, superzoom lenses are noted for having poorer optical quality at the extreme focal length ranges, mostly distortion at max wide angle and long lens ranges. The long focal lengths normally have to be combined with image stabilization.Chris Gatcum, The Beginner's Photography Guide, Dorling Kindersly Limited/Penguin - 2013, page 107 See also * List of superzoom compact cameras This is a list of superzoom compact cameras, sometimes also called as superzoom 'travel' compact cameras.

MultiMedia Card
The MultiMediaCard, officially abbreviated as MMC, is a memory card standard used for solid-state storage. Unveiled in 1997 by SanDisk and Siemens, MMC is based on a surface-contact low pin-count serial interface using a single memory stack substrate assembly, and is therefore much smaller than earlier systems based on high pin-count parallel interfaces using traditional surface-mount assembly such as CompactFlash. Both products were initially introduced using SanDisk NOR-based flash technology. MMC is about the size of a postage stamp: 32 mm × 24 mm × 1.4 mm. MMC originally used a 1-bit serial interface, but newer versions of the specification allow transfers of 4 or 8 bits at a time. MMC can be used in many devices that can use Secure Digital (SD) cards. Typically, an MMC operates as a storage medium for devices, in a form that can easily be removed for access by a PC via a connected MMC reader. Modern computers, both laptops and desktops, often have SD slot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
