Pocket Video Camera
A pocket video camera is a tapeless camcorder that is small enough to be carried in one's pocket. A typical pocket video camera has an LCD screen of at least 1.5", the ability to capture either only standard video or both standard video and high-definition video ( H.264/MPEG-4 AVC), at least 128MB of internal memory and a Secure Digital (SD) card extension or at least 4GB internal memory with no SD card slot. Power may be supplied by a proprietary Ni-MH rechargeable battery or 2 standard AA batteries. Dimensions 2.5 x 4.5 x 0.9 in and a weight of 3.8 oz are typical, and a USB connector is usually built-in. Pocket camcorders weigh only from 0.2 to 0.4 lbs and fit neatly into any pocket or purse for ultra portability. Examples include the Creative Vado HD and the Flip Video. The Sony Bloggie MHS-PM5 can shoot video in Full HD and has 4x digital zoom Digital zoom is a method of decreasing the precise angle of view of a digital photograph or video image.

Flip Video
The Flip Video cameras were an American series of tapeless camcorders for digital video created by Pure Digital Technologies, a company bought by Cisco Systems in March 2009; variants included the UltraHD, the MinoHD, and the SlideHD. Flip Video cameras were known for their simple interface with few buttons, minimal menus and built in USB plugs (from which they derived the flip name), and were marketed as making video "simple to shoot, simple to share" Production of the line of Flip video cameras ran from 2006 until April 2011, when Cisco Systems discontinued them as part of a move to "...exit aspects of (their) consumer businesses." Flip cameras contributed to an increase in the popularity of similar pocket camcorders, although the inclusion of HD video cameras in many smartphones has since made them a more niche product. Features Flip cameras can record videos at different resolutions. FlipHD camcorders digitally record high-definition video at 1280 x 720 resolution using ...

Tapeless Camcorder
A camcorder is a self-contained portable electronic device with video and recording as its primary function. It is typically equipped with an articulating screen mounted on the left side, a belt to facilitate holding on the right side, hot-swappable battery facing towards the user, hot-swappable recording media, and an internally contained quiet optical zoom lens. The earliest camcorders were tape-based, recording analog signals onto videotape cassettes. In 2006, digital recording became the norm, with tape replaced by storage media such as mini-HD, microDVD, internal flash memory and SD cards. More recent devices capable of recording video are camera phones and digital cameras primarily intended for still pictures, whereas dedicated camcorders are often equipped with more functions and interfaces than more common cameras, such as an internal optical zoom lens that is able to operate silently with no throttled speed, whereas cameras with protracting zoom lenses commonly throttl ...

Liquid Crystal Display
A liquid-crystal display (LCD) is a flat panel display, flat-panel display or other Electro-optic modulator, electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly but instead use a backlight or reflector (photography), reflector to produce images in color or monochrome monitor, monochrome. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images with low information content, which can be displayed or hidden. For instance: preset words, digits, and seven-segment displays, as in a digital clock, are all good examples of devices with these displays. They use the same basic technology, except that arbitrary images are made from a matrix of small pixels, while other displays have larger elements. LCDs can either be normally on (positive) or off (negative), depending on the polarizer arrangement. For example, a character ...

High-definition Video
High-definition video (HD video) is video of higher resolution and quality than standard-definition. While there is no standardized meaning for ''high-definition'', generally any video image with considerably more than 480 vertical scan lines (North America) or 576 vertical lines (Europe) is considered high-definition. 480 scan lines is generally the minimum even though the majority of systems greatly exceed that. Images of standard resolution captured at rates faster than normal (60 frames/second North America, 50 fps Europe), by a high-speed camera may be considered high-definition in some contexts. Some television series shot on high-definition video are made to look as if they have been shot on film, a technique which is often known as filmizing. History The first electronic scanning format, 405 lines, was the first ''high definition'' television system, since the mechanical systems it replaced had far fewer. From 1939, Europe and the US tried 605 and 441 lines until, in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secure Digital
Secure Digital, officially abbreviated as SD, is a proprietary format, proprietary non-volatile memory, non-volatile Flash memory, flash memory card format developed by the SD Association, SD Association (SDA) for use in portable devices. The standard was introduced in August 1999 by joint efforts between SanDisk, Panasonic (Matsushita) and Toshiba as an improvement over MultiMediaCard, MultiMediaCards (MMCs), and has become the industry standard. The three companies formed SD-3C, LLC, a company that licenses and enforces intellectual property rights associated with SD memory cards and SD host and ancillary products. The companies also formed the SD Association (SDA), a non-profit organization, in January 2000 to promote and create SD Card standards. SDA today has about 1,000 member companies. The SDA uses several trademarked logos owned and licensed by SD-3C to enforce compliance with its specifications and assure users of compatibility. History 1999–2003: Creation In 1 ...

Rechargeable Battery
A rechargeable battery, storage battery, or secondary cell (formally a type of Accumulator (energy), energy accumulator), is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use. It is composed of one or more electrochemical cells. The term "accumulator" is used as it accumulator (energy), accumulates and energy storage, stores energy through a reversible electrochemical Chemical reaction, reaction. Rechargeable batteries are produced in many different shapes and sizes, ranging from Button cell#Rechargeable variants, button cells to megawatt systems connected to grid energy storage, stabilize an electrical distribution network. Several different combinations of electrode materials and electrolytes are used, including lead–acid battery, lead–acid, zinc–air battery, zinc–air, nickel–cadmium battery, nickel–cadmium (Ni ...

Creative Vado HD
The Vado is any of a series of pocket video cameras developed and manufactured by Creative Labs. The original 640x480 VGA resolution Vado was first introduced in May 2008. A high-definition model, the Creative Vado HD was then made available in December 2008. Designed to be handheld and easily portable, the Vado series of pocket camcorders compete directly with similar devices such as the Flip Video and Sony Bloggie MHS-PM5. All Creative Vado and Creative Vado HD units feature a tripod mount, anti- AC-flicker feature which can be set for 50 Hz and 60 Hz regions, as well as RCA TV out functionality. The image sensors in all Vado units use CMOS technology for improved low-light sensitivity. Vados are powered by Lithium-Ion batteries, charged via USB power. The USB connector can be found at the bottom of the unit, and is held in place magnetically. When a USB connection is required, the flexible male A-type USB connector is simply pulled out of its place and connected to a comp ...
