instant cameraThe instant camera is a type of camera thatgenerates a developed film image. Themost popular types to use self-developingfilm were formerly made by PolaroidCorporation.
Digital camera-A digital camera (or digicam) is acamera that takes video or stillphotographs by recording images on anelectronic image sensor
Digital and film cameras share an opticalsystem, typically using a lens with a variablediaphragm to focus light onto an image pickupdevice. The diaphragm and shutter admit the correctamount of light to the imager, just as with film butthe image pickup device is electronic rather thanchemical. However, unlike film cameras, digitalcameras can display images on a screen immediatelyafter being recorded, and store and delete imagesfrom memory. Many digital cameras can also recordmoving video with sound.
Video camera -A video camera is a camera used for electronicmotion picture acquisition, initially developed bythe television industry but now common in other applications as well
-camcorderA camcorder (formally a video camera recorder)is an electronic device that combines a videocamera and a video recorder into one unit;typically for out-of-studio consumer videorecording.[
Professional video cameraA professional video camera (often called a televisioncamera even though the use has spread beyondtelevision) is a high-end device for creating electronicmoving images (as opposed to a movie camera, thatrecords the images on film).
Closed-circuit television camera-Closed-circuit television (CCTV) cameras can produce images or recordings forsurveillance purposes, and can be either video cameras, or digital stills cameras.
A remote camera is a cameraplaced by a photographer inareas where the photographergenerally cannot be. Thisincludes areas with limitedaccess, tight spaces where aperson is not allowed, or justanother angle so that thephotographer cansimultaneously take pictures ofthe same moment fromdifferent locations.
An Internet protocolcamera, or IP camera, is a typeof digital video cameracommonly employed forsurveillance, and which unlikeanalog closed circuit television(CCTV) cameras can send andreceive data via a computernetwork and the Internet.Although most cameras thatdo this are webcams, the term"IP camera" or "netcam" isusually applied only to thoseused for surveillance.
The movie camera is a type of photographic camerawhich takes a rapid sequence of photographs on stripsof film. The video camera has largely replaced it forprivate use, but for professional purposes, moviecameras are used and produced today, especially forthe production of full-feature movies.
In contrast to a still camera, which capturesa single snapshot at a time, the moviecamera takes a series of images; "frame".This is accomplished through anintermittent mechanism. The frames arelater played back in a movie projector at aspecific speed, called the frame rate(number of frames per second). Whileviewing, a persons eyes and brain mergethe separate pictures together to create theillusion of motion.
A pinhole camera is a simplecamera without a lens andwith a single small aperture –effectively a light-proof boxwith a small hole in one side.Light from a scene passesthrough this single point andprojects an inverted image onthe opposite side of the box.The human eye in bright lightacts similarly, as do camerasusing small apertures.
Rangefinder cameraA rangefinder camera is a camera fitted with arangefinder: a range-finding focusing mechanismallowing the photographer to measure the subjectdistance and take photographs that are in sharpfocus.
Most varieties of rangefinder show twoimages of the same subject, one of whichmoves when a calibrated wheel is turned;when the two images coincide and fuse intoone, the distance can be read off the wheel.Older, non-coupled rangefinder camerasdisplay the focusing distance and requirethe photographer to transfer the value tothe lens focus ring; cameras without built-inrangefinders could have an externalrangefinder fitted into the accessory shoe.
Camera phoneA camera phone is a mobile phone which is ableto capture still photographs (and usually video). Since early in the 21st century the majority of mobile phones in use are camera phones
A single-lens reflex (SLR) camera is a camera thattypically uses a mirror and prism system (hence"reflex", from the mirrors reflection) that permits thephotographer to view through the lens and seeexactly what will be captured, contrary to viewfindercameras where the image could be significantlydifferent from what will be captured.
Most camera phones are simpler than separatedigital cameras. Their usual fixed focus lensesand smaller sensors limit their performance inpoor lighting. Lacking a physical shutter, mosthave a long shutter lag. Flash, wherepresent, is usually weak. Optical zoom andtripod screws are rare. Some also lack a USBconnection, removable memory card, or otherway of transferring their pictures more quicklythan by the phones inherent communicationfeature.
A twin-lens reflex camera (TLR) is a type of camerawith two objective lenses of the same focal length. Oneof the lenses is the photographic objective or "takinglens" (the lens that takes the picture), while the other isused for the viewfinder system, which is usually viewedfrom above at waist level. In addition to theobjective, the viewfinder consists of a 45-degree mirror(the reason for the word reflex in the name), a mattefocusing screen at the top of the camera, and a pop-uphood surrounding it. The two objectives areconnected, so that the focus shown on the focusingscreen will be exactly the same as on the film.
a toy camera refers to a simple, inexpensive filmcamera. Despite the name, they are in fact always fullyfunctional and capable of taking photographs, albeitwith optical aberrations due to the limitations of thesimple lenses.
A virtual camera system aims atcontrolling a camera or a set of camerasto display a view of a 3D virtual world.Camera systems are used in videogameswhere their purpose is to show theaction at the best possible angle; moregenerally, they are used in 3D virtualworlds when a third person view isrequired.
