Olympus Corporation
is a Japanese manufacturer of optics and reprography products. Olympus was established on 12 October 1919, initially specializing in microscopes and thermometers. Olympus holds roughly a 70-percent share of the global endoscope market, estimated to be worth approximately US$2.5 billion. Its global headquarters are located in Shinjuku, Tokyo, Japan. In 2011, Olympus attracted worldwide media scrutiny when it fired its CEO and the matter snowballed into a corporate corruption investigation with multiple arrests. It paid $646 million in kickback fines in 2016. Products Cameras and audio In 1936, Olympus introduced its first camera, the Semi-Olympus I, fitted with the first Zuiko-branded lens. The Olympus Chrome Six was a series of folding cameras made by Takachiho, and later Olympus, from 1948 to 1956, for 6×4.5 cm or 6×6 cm exposures on 120 film. The first innovative camera series from Olympus was the Pen, launched in 1959. It used a half-frame format, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Articulating Screen
An articulating screen is a built-in small electronic visual display which is not fixed, but rather can be repositioned using a hinge or pivot. The articulating screen is known under different other names such as flip-out screen, flip screen, adjustable screen, articulated screen, or hinged screen. According to the way it moves, there are four main types: #The display moves around one axis, so that it only tilts. It is called ''tilting screen'' or ''tiltable screen''. #The display tilts horizontally both up and down and also vertically. This type is called ''double-hinged tilting screen'', ''two-axis tilting screen'', ''three-direction tilting screen'' or ''screen with 3-way tilt''. #The display moves around two axes which are at a right angle to each other, so that the screen both tilts and swivels. This type is called ''swivel screen''. Other names for this type are ''vari-angle screen'', ''fully articulated screen'', ''fully articulating screen'', ''rotating screen'', ''multi-an ...

Vignetting
In photography and optics, vignetting is a reduction of an image's brightness or saturation toward the periphery compared to the image center. The word ''vignette'', from the same root as ''vine'', originally referred to a decorative border in a book. Later, the word came to be used for a photographic portrait that is clear at the center and fades off toward the edges. A similar effect is visible in photographs of projected images or videos off a projection screen, resulting in a so-called "hotspot" effect. Vignetting is often an unintended and undesired effect caused by camera settings or lens limitations. However, it is sometimes deliberately introduced for creative effect, such as to draw attention to the center of the frame. A photographer may deliberately choose a lens that is known to produce vignetting to obtain the effect, or it may be introduced with the use of special filters or post-processing procedures. When using superzoom lenses, vignetting may occur all alo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supersonic Wave Filter
Supersonic speed is the speed of an object that exceeds the speed of sound ( Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately . Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.2. Sounds are traveling vibrations in the form of pressure waves in an elastic medium. Objects move at supersonic speed when the objects move faster than the speed at which sound propagates through the medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, the speed of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dust Reduction System
A dust reduction system, or dust removal system, is used in several makes of digital cameras to remove dust from the image sensor. Every time lenses are changed, dust may enter the camera body and settle on the image sensor. Digital single-lens reflex cameras (DSLR) are particularly vulnerable to this issue, since the interior of the camera is exposed during lens changes unlike other forms of digital cameras, and the image sensor is fixed, unlike a film camera. Even the tiniest (micrometre-size) dust particles or other contaminants that settle on the face of the image sensor (individual pixels of which have dimensions on the order of ~5 micrometres) may cast shadows and thus become visible in the final image as more or less diffuse grey blobs, depending on aperture. Dust may be generated by internal moving parts or may be moved by air currents within the camera. Some systems remove or clean the sensor by vibrating at a very high frequency—between 100 hertz and 50 kilohertz. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Image Stabilization
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation. It is mainly used in high-end image-stabilized binoculars, still and video cameras, astronomical telescopes, and also smartphones. With still cameras, camera shake is a particular problem at slow shutter speeds or with long focal length lenses (telephoto or zoom). With video cameras, camera shake causes visible frame-to-frame jitter in the recorded video. In astronomy, the problem of lens shake is added to variation in the atmosphere, which changes the apparent positions of objects over time. Application in still photography In photography, image stabilization can facilitate shutter speeds 2 to 5.5 stops slower (exposures 4 to times l ...

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 ...

Lithium-ion Battery
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
