Image Sensor
An image sensor or imager is a sensor that detects and conveys information used to form an image. It does so by converting the variable attenuation of light waves (as they refraction, pass through or reflection (physics), reflect off objects) into signal (electrical engineering), signals, small bursts of electric current, current that convey the information. The waves can be light or other electromagnetic radiation. Image sensors are used in electronics, electronic imaging devices of both analogue electronics, analog and digital electronics, digital types, which include digital cameras, camera modules, camera phones, optical mouse devices, medical imaging equipment, night vision equipment such as thermography, thermal imaging devices, radar, sonar, and others. As technological change, technology changes, electronic and digital imaging tends to replace chemical and analog imaging. The two main types of electronic image sensors are the charge-coupled device (CCD) and the active-pixel s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Live Preview
Live preview is a feature that allows a digital camera's display screen to be used as a viewfinder. This provides a means of previewing framing and other exposure before taking the photograph. In most such cameras, the preview is generated by means of continuously and directly projecting the image formed by the lens onto the main image sensor. This in turn feeds the electronic screen with the live preview image. The electronic screen can be either a liquid crystal display (LCD) or an electronic viewfinder (EVF). Background The concept for cameras with live preview largely derives from electronic (video) TV cameras. Until 1995 most digital cameras did not have live preview, and it was more than ten years after this that the higher end digital single-lens reflex cameras (DSLR) adopted this feature, as it is fundamentally incompatible with the swinging-mirror single-lens reflex mechanism. The first digital still camera with an LCD for autogain framing live preview was th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Four Thirds System
The Four Thirds System is a standard created by Olympus Corporation, Olympus and Eastman Kodak for digital single-lens reflex camera (DSLR) design and development. Four Thirds refers to both the size of the image sensor (4/3") as well as the aspect ratio (4:3). The Olympus E-1 was the first Four Thirds DSLR, announced and released in 2003. In 2008, Olympus and Panasonic began publicizing the Micro Four Thirds system, a mirrorless camera system which used the same sensor size; by eliminating the reflex mirror, the Micro Four Thirds cameras were significantly smaller than the Four Thirds cameras. The first Micro Four Thirds cameras were released in 2009 and the final Four Thirds cameras were released in 2010; by that time, approximately 15 Four Thirds camera models had been released by Olympus and Panasonic in total. The system provides a Standardization, standard that permits interoperability of digital cameras and Lenses for SLR and DSLR cameras, lenses made by different manuf ...

APS-C
Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2 and Ø 30.15 mm field diameter. It is therefore also equivalent in size to the Super 35 motion picture film format, which has the dimensions of 24.89 mm × 18.66 mm (0.980 in × 0.735 in) and Ø 31.11 mm field diameter. Sensors approximating these dimensions are used in many digital single-lens reflex cameras (DSLRs), mirrorless interchangeable-lens cameras (MILCs), and a few large-sensor live-preview digital cameras. APS-C size sensors are also used in a few digital rangefinder camera, rangefinders. Such sensors exist in many different variants depending on the manufacturer and camera model. All APS-C variants are considerably smaller than 35 mm standard film which measures 36×24 mm. Because of this, devices with APS-C sensors a ...

Image Sensor Format
In digital photography, the image sensor format is the shape and size of the image sensor. The image sensor format of a digital camera determines the angle of view of a particular lens when used with a particular sensor. Because the image sensors in many digital cameras are smaller than the 24 mm × 36 mm image area of full-frame 35 mm format, 35 mm cameras, a lens of a given focal length gives a narrower field of view in such cameras. Sensor size is often expressed as optical format in inches. Other measures are also used; see table of sensor formats and sizes below. Lenses produced for 35 mm film cameras may mount well on the digital bodies, but the larger image circle of the 35 mm system lens allows unwanted light into the camera body, and the smaller size of the image sensor compared to 35 mm film format results in cropping of the image. This latter effect is known as field-of-view crop. The format size ratio (relative to the 35 mm film ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olympus E-300
The Olympus E-300 (Olympus Evolt E-300 in North America) is an 8-megapixel digital SLR manufactured by Olympus of Japan and based on the Four Thirds System. Announced at photokina 2004, it became available at the end of 2004. It was the second camera (after the Olympus E-1) to use the Four Thirds System, and the first intended for the consumer market. Features The camera's appearance was unique, as it lacked the ubiquitous SLR pentaprism "hump". Instead, a Porro prism system was used; it fitted sideways within the camera, with a sideways-swinging mirror, and located the viewfinder eyepiece to the left (seen from behind) relative to the lens centerline. The body was largely of ABS plastic over a metal frame; the lens mount was metal, and there was a metal covered area on the left top of the camera. This area also contained the onboard flash, which popped up and forward at the touch of a button. The onboard flash popup mechanism is manual. In low light scenarios the flash will n ...

Olympus E-1
The Olympus E-1, introduced in 2003, was the first DSLR system camera designed from the ground up for digital photography This contrasts with its contemporaries which offered systems based on reused parts from previous 135 film systems, modified to fit with a sensor size of APS-C. Features The E-1 uses the Four Thirds System lens mount and imaging system. This design choice means that because the CCD is smaller than a 35 mm negative, Four Thirds System lenses and camera bodies can be made smaller and lighter than those of preceding SLRs. Characteristics: *Lighter/more compact than contemporary DSLR bodies *5 megapixel CCD *Magnesium-alloy body *Environmental sealing (splash proof) *"Supersonic Wave Filter" dust reduction system cleans CCD at each camera start-up (dust is shaken off the CCD) *USB 2.0 and FireWire connectivity *Continuous shooting 3 frames per second up to 12 frames *Hybrid white balance sensor (on external surface of camera and using CCD) *User up ...

Image Noise
Image noise is random variation of brightness or color information in images. It can originate in film grain and in the unavoidable shot noise of an ideal photon detector. In digital photography is usually an aspect of electronic noise, produced by the image sensor of a digital camera. The circuitry of a Image scanner, scanner can also contribute to the effect. Image noise is often (but not necessarily) an undesirable by-product of image capture that obscures the desired information. Typically the term “image noise” is used to refer to noise in 2D images, not 3D images. The original meaning of "noise" was "unwanted signal"; Noise (radio), unwanted electrical fluctuations in signals received by AM radios caused audible acoustic noise ("static"). By analogy, unwanted electrical fluctuations are also called "noise". Image noise can range from almost imperceptible specks on a digital photograph taken in good light, to Optical astronomy, optical and Radioastronomy, radioast ...

Olympus E-500
The Olympus E-500 (Olympus EVOLT E-500 in North America) is an 8-megapixel digital SLR camera manufactured by Olympus of Japan and based on the Four Thirds System. It was announced on 26 September 2005. Like the E-300 launched the previous year, it uses a Full Frame Transfer (17.3 x 13 mm) Kodak KAF-8300CE CCD imaging chip. Features Unlike the E-300 and the E-300's successor, the Olympus E-330, the E-500 retains the traditional SLR appearance, with a humped pentamirror box instead of the E-300's unique Porro mirror arrangement. The mirror box also bears the onboard flash. The viewfinder hump means the E-500 is taller than the E-300, but in other dimensions it is smaller. The E-500 uses Olympus' patented Supersonic Wave Filter dust reduction system to shake dust from the sensor during startup and when requested by the user; this largely eliminates the problem of dust accumulation on the surface of the image sensor. Image processing is done with Olympus' TruePic Turbo syst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olympus E-410
The Olympus E-410 (or Olympus EVOLT E-410 in North America) is a 10 megapixel digital single-lens reflex (DSLR) camera intended be the smallest and lightest DSLR on the market. Announced in March 2007 to succeed the E-400 (which was only marketed in Europe), it adds a live preview function and a new "Olympus TruePic III" processing chip that is claimed to provide better performance. The E-410 body and lens mount conform to the Four Thirds System standard, providing compatibility with other lenses for that system. (Four Thirds System lenses are smaller and lighter than lenses with similar specifications from other DSLR systems.) Like the E-400, the E-410 is notable for its small size, omitting the hand grip and exploiting the smaller sensor of the Four Thirds System. It weighs only 375g and approaches manual focus film SLR sizes, reminiscent of the Olympus OM system. It is accompanied by two new small zoom lenses, a 14–42 mm (28–84 mm 135 film format equivalent) f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olympus E-400
The Olympus E-400 is a digital single-lens reflex camera launched by Olympus on 14 September 2006, using the Four Thirds System lens mount standard. This 10 megapixel camera could be compared to other DSLRs unveiled during the summer of 2006 with comparable pixel count and price range: the Sony α 100, the Nikon D80, the Canon EOS 400D and the Pentax K10D. Features The E-400 is notable for its small size, omitting the hand grip and exploiting the smaller sensor. It weighs only 375g and approaches manual focus film SLRs sizes, reminiscent of the Olympus OM system.
