Samsung Group (; stylised as SΛMSUNG) is a South Korean multinational manufacturing conglomerate headquartered in the Samsung Town office complex in Seoul. The group consists of numerous affiliated businesses, most of which operate under the Samsung brand, and is the largest (business conglomerate) in South Korea. Samsung has the world's fifth-highest brand value. Founded in 1938 by Lee Byung-chul as a trading company, Samsung diversified into various sectors, including food processing, textiles, insurance, securities, and retail, over the next three decades. In the late 1960s, Samsung entered the electronics industry, followed by the construction and shipbuilding sectors in the mid-1970s—areas that would fuel its future growth. After Lee died in 1987, Samsung was divided into five business groups: Samsung Group, Shinsegae Group, CJ Group, Hansol Group, and JoongAng Group. Key affiliates of Samsung include Samsung Electronics, the world's largest information techn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qualcomm Snapdragon
Snapdragon is a suite of system-on-chip (SoC) semiconductor products for mobile devices designed and marketed by Qualcomm, who often refers to these SoCs as "mobile platforms". They typically integrate central processing units (CPU) based on the ARM architecture, a graphics processing unit (GPU), some digital signal processors (DSP), and may or may not include a cellular modem. Snapdragon semiconductors are designed for embedded systems, e.g., smartphones, netbooks, and vehicles. In addition to the processors, the lineup also includes modems, Wi-Fi chips and mobile charging products. The first Snapdragon-branded product was released in December 2007, using CPU based on Qualcomm’s “Scorpion” microarchitecture. The architecture’s successor, “Krait”, was introduced in 2011 and featured asynchronous symmetrical multi-processing: cores can adjust their clock speed and voltage independent of each other. On the announcement of Snapdragon 800 in 2013 Consumer E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Display Aspect Ratio
The display aspect ratio (DAR) is the Aspect ratio (image), aspect ratio of a display device and so the proportional relationship between the display size, physical width and the height of the display. It is expressed as two numbers separated by a colon (''x'':''y''), where ''x'' corresponds to the width and ''y'' to the height. Common aspect ratios for displays, past and present, include 5:4, 4:3, 16:10, and 16:9. To distinguish: * The display aspect ratio (DAR) is calculated from the physical width and height of a display, measured each in inch or Centimetre, cm (Display size). * The pixel aspect ratio, pixel aspect ratio (PAR) is calculated from the width and height of one pixel. * The storage aspect ratio, storage aspect ratio (SAR) is calculated from the numbers of pixels in width and height stated in the Graphics display resolution, display resolution. Because the units cancel out, all aspect ratios are unitless. Diagonal and area The size of a television set or computer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AMOLED
AMOLED (active-matrix organic light-emitting diode; ) is a type of OLED display device technology. OLED describes a specific type of thin-film-display technology in which organic compounds form the electroluminescence, electroluminescent material, and active matrix refers to the technology behind the addressing of pixels. Since 2007, AMOLED technology has been used among mobile phones, media players, TVs and digital cameras, and the current progress over this technology is in lower power usage, lower cost, better resolution and specifically for larger screen (e.g. 8k screens). Design An AMOLED display consists of an active matrix of OLED pixels generating light (luminescence) upon electrical activation that have been deposited or integrated onto a thin-film transistor (TFT) array, which functions as a series of switches to control the current flowing to each individual pixel. Typically, this continuous current flow is controlled by at least two TFTs at each pixel (to trigger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Image Stabilization
Image stabilization (IS) is a family of techniques that reduce motion blur, blurring associated with the motion of a camera or other imaging device during exposure (photography), exposure. Generally, it compensates for panning (camera), pan and tilt (camera), tilt (angular movement, equivalent to aircraft principal axes, yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation about the optical axis (aircraft principal axes, roll). It is mainly used in high-end image-stabilized binoculars, digital camera, still and video camera, 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 lens, telephoto or zoom lens, zoom). With video cameras, camera shake causes visible frame-to-frame jitter (optics), jitter in the recorded video. In astronomy, the problem of lens shake is added to Astronomical seeing, ...

Autofocus
An autofocus (AF) optical system uses a sensor, a control system and a motor to focus on an automatically or manually selected point or area. An electronic rangefinder has a display instead of the motor; the adjustment of the optical system has to be done manually until indication. Autofocus methods are distinguished as active, passive or hybrid types. Autofocus systems rely on one or more sensors to determine correct focus. Some AF systems rely on a single sensor, while others use an array of sensors. Most modern SLR cameras use through-the-lens optical sensors, with a separate sensor array providing light metering, although the latter can be programmed to prioritize its metering to the same area as one or more of the AF sensors. Through-the-lens optical autofocusing is usually speedier and more precise than manual focus with an ordinary viewfinder, although more precise manual focus can be achieved with special accessories such as focusing magnifiers. Autofocus accur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultra Wide Angle Lens
An ultra wide-angle lens is a Photographic lens, lens whose focal length is shorter than that of an average wide-angle lens, providing an even wider view. The term denotes a different range of lenses, relative to the size of the sensor in the camera in question. * For 1" any 9mm or shorter is considered ultra wide angle. * For Four Thirds system, 4/3" any 10 mm or shorter lens is considered ultra wide angle. * For APS-C any lens shorter than 15 mm. * For 35mm format, 35mm film or full-frame sensor any lens shorter than 24 mm * For Medium format (film), 6x4.5 cm any lens shorter than 41 mm * For Medium format (film), 6x6 cm and Medium format (film), 6x7 cm any lens shorter than 56 mm Features 'Fisheye' and rectilinear lenses Ultra-wide angle lenses come in two varieties: Fisheye lenses with curvilinear perspective, curvilinear barrel distortion, and rectilinear lenses which are designed so that straight lines in the scene will render straight (uncurv ...

Telephoto Lens
A telephoto lens, also known as telelens, is a specific type of a long-focus lens used in photography and cinematography, in which the physical length of the lens is shorter than the focal length. This is achieved by incorporating a special lens group known as a ''telephoto group'' that extends the light path to create a long-focus lens in a much shorter overall design. The angle of view and other effects of long-focus lenses are the same for telephoto lenses of the same specified focal length. Long-focal-length lenses are often informally referred to as ''telephoto lenses'', although this is technically incorrect: a telephoto lens specifically incorporates the telephoto group. Construction A simple photographic lens may be constructed using one lens element of a given focal length; to focus on an object at infinity, the distance from this single lens to focal plane of the camera (where the sensor or film is) has to be adjusted to the focal length of that lens. For example, g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
F-number
An f-number is a measure of the light-gathering ability of an optical system such as a camera lens. It is calculated by dividing the system's focal length by the diameter of the entrance pupil ("clear aperture").Smith, Warren ''Modern Optical Engineering'', 4th Ed., 2007 McGraw-Hill Professional, p. 183. The f-number is also known as the focal ratio, f-ratio, or f-stop, and it is key in determining the depth of field, diffraction, and Exposure (photography), exposure of a photograph. The f-number is dimensionless number, dimensionless and is usually expressed using a lower-case Ƒ, hooked f with the format ''N'', where ''N'' is the f-number. The f-number is also known as the inverse relative aperture, because it is the Multiplicative inverse, inverse of the relative aperture, defined as the aperture diameter divided by focal length. The relative aperture indicates how much light can pass through the lens at a given focal length. A lower f-number means a larger relative apertur ...
