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, act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Single-lens Reflex Camera
A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor. The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens and then to a mirror that alternates to send the image to either a prism, which shows the image in the viewfinder, or the image sensor when the shutter release button is pressed. The viewfinder of a DSLR presents an image that will not differ substantially from what is captured by the camera's sensor as it presents it as a direct optical view through the main camera lens, rather than showing an image through a separate secondary lens. DSLRs largely replaced film-based SLRs during the 2000s. Major camera manufacturers began to transition their product lines away from DSLR cameras to mirrorless interchangeable-lens cameras (MILC) beginning in the 2010s ...

Superzoom
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.

Bridge Camera
Bridge cameras are cameras that fill the niche between relatively simple point-and-shoot cameras and interchangeable-lens cameras such as mirrorless cameras and single-lens reflex cameras (SLRs). They are often comparable in size and weight to the smallest digital SLRs (DSLR), but lack interchangeable lenses, and almost all digital bridge cameras lack an optical viewfinder system. The phrase "bridge camera" has been in use at least since the 1980s, and continues to be used with digital cameras. The term was originally used to refer to film cameras which "bridged the gap" between point-and-shoot cameras and SLRs. Like other cameras, most current bridge cameras are digital. These cameras typically feature full manual controls over shutter speed, aperture, ISO sensitivity, color balance and metering. Generally, their feature sets are similar to consumer DSLRs, except for a smaller range of ISO sensitivity because of their typically smaller image sensor. Many bridge cameras ...

Focal Length
The focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power. A positive focal length indicates that a system converges light, while a negative focal length indicates that the system diverges light. A system with a shorter focal length bends the rays more sharply, bringing them to a focus in a shorter distance or diverging them more quickly. For the special case of a thin lens in air, a positive focal length is the distance over which initially collimated (parallel) rays are brought to a focus, or alternatively a negative focal length indicates how far in front of the lens a point source must be located to form a collimated beam. For more general optical systems, the focal length has no intuitive meaning; it is simply the inverse of the system's optical power. In most photography and all telescopy, where the subject is essentially infinitely far away, longer focal length (lower opti ...

Nikon Coolpix P900
The Nikon Coolpix P900 is a superzoom digital bridge camera announced by Nikon on March 2, 2015. With 83× zoom limit and a maximum 2000 mm 35 mm equivalent focal length, it was the greatest-zooming bridge camera at the time of its announcement, a record it held for almost two years, until the release of Kodak's Pixpro Astro Zoom AZ901 in early 2017 with its 90× zoom ratio. The record was later overtaken by the P900's successor, the Nikon P1000 on September 6, 2018, a record it still holds as of September 2020. The P900 complemented its shorter-zooming sister model, the Nikon Coolpix P610 The Nikon Coolpix P610 is a superzoom bridge camera announced by Nikon on February 10, 2015. It differs from its predecessor, the Nikon Coolpix P600, with the inclusion of a sensor to automatically switch between monitor mode and the electronic v ..., which was announced a few weeks earlier.

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 ...

Cameras Introduced In 2014
A camera is an optical instrument that can capture an image. Most cameras can capture 2D images, with some more advanced models being able to capture 3D images. At a basic level, most cameras consist of sealed boxes (the camera body), with a small hole (the aperture) that allows light to pass through in order to capture an image on a light-sensitive surface (usually a digital sensor or photographic film). Cameras have various mechanisms to control how the light falls onto the light-sensitive surface. Lenses focus the light entering the camera, and the aperture can be narrowed or widened. A shutter mechanism determines the amount of time the photosensitive surface is exposed to the light. The still image camera is the main instrument in the art of photography. Captured images may be reproduced later as part of the process of photography, digital imaging, or photographic printing. Similar artistic fields in the moving-image camera domain are film, videography, and cinematograph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
