HTC One (M8)
The HTC One (M8) (also marketed as the all-new HTC One) is an Android or Windows smartphone manufactured and marketed by HTC. Following a number of leaks that occurred during the months prior, the device was officially unveiled in a press conference on March 25, 2014, and released the same day by Verizon Wireless at retail, and by other Canadian and United States carriers for online orders prior to its wider retail availability in mid-April. The device retains a similar design to the HTC One (M7), its predecessor in the HTC One series, but features a larger, rounded chassis incorporating a 5-inch 1080p display, a quad-core Qualcomm Snapdragon 801 processor, a depth of field sensor which can be used to individually refocus and apply various effects to the foreground and background elements of photos taken with the device's camera, a higher resolution front camera, improvements to the device's front-facing stereo speakers, expandable storage, new gesture functionality, and a refres ...

Accelerometer
An accelerometer is a device that measures the proper acceleration of an object. Proper acceleration is the acceleration (the rate of change (mathematics), rate of change of velocity) of the object relative to an observer who is in free fall (that is, relative to an inertial frame of reference). Proper acceleration is different from coordinate acceleration, which is acceleration with respect to a given coordinate system, which may or may not be accelerating. For example, an accelerometer at rest on the surface of the Earth will measure an Gravitational acceleration, acceleration due to Earth's gravity straight upwards of about Standard gravity, ''g'' ≈ 9.81 m/s2. By contrast, an accelerometer that is in free fall will measure zero acceleration. Accelerometers have many uses in industry, consumer products, and science. Highly sensitive accelerometers are used in inertial navigation systems for aircraft and missiles. In unmanned aerial vehicles, accelerometers help to stabili ...

Wi-Fi Direct
Wi-Fi Direct is a Wi-Fi standard for wireless connections that allows two devices to establish a direct Wi-Fi connection without an intermediary wireless access point, Router (computing), router, or Internet connection. Wi-Fi Direct is single-hop communication, rather than Multi-hop routing, multi-hop communication like Wireless ad hoc network, wireless ad hoc networks. The Wi-Fi Direct standard was specified in 2009. It is useful for things such as file transfer, casting and projecting with Miracast, wireless printing, and to communicate with one or more devices simultaneously at typical Wi-Fi speeds (IEEE 802.11) without requiring a hotspot or an Internet connection. It is therefore similar to Bluetooth technology but offers a longer range. Only one of the Wi-Fi devices needs to be compliant with Wi-Fi Direct to establish a peer-to-peer connection. Wi-Fi Direct negotiates the link with a Wi-Fi Protected Setup system that assigns each device a limited wireless access point. The ...

Wi-Fi
Wi-Fi () is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for Wireless LAN, local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks, used globally in small office/home office, home and small office networks to link devices and to provide Internet access with wireless routers and wireless access points in public places such as coffee shops, restaurants, hotels, libraries, and airports. ''Wi-Fi'' is a trademark of the Wi-Fi Alliance, which restricts the use of the term "''Wi-Fi Certified''" to products that successfully complete Interoperability Solutions for European Public Administrations, interoperability certification testing. Non-compliant hardware is simply referred to as WLAN, and it may or may not work with "''Wi-Fi Certified''" devices. the Wi-Fi Alliance consisted of more than 800 companies from ar ...

Depth Of Field
The depth of field (DOF) is the distance between the nearest and the farthest objects that are in acceptably sharp focus (optics), focus in an image captured with a camera. See also the closely related depth of focus. Factors affecting depth of field For cameras that can only focus on one object distance at a time, depth of field is the distance between the nearest and the farthest objects that are in acceptably sharp focus in the image. "Acceptably sharp focus" is defined using a property called the "circle of confusion". The depth of field can be determined by focal length, distance to subject (object to be imaged), the acceptable circle of confusion size, and aperture. Limitations of depth of field can sometimes be overcome with various techniques and equipment. The approximate depth of field can be given by: \text \approx \frac for a given maximum acceptable circle of confusion , focal length , f-number , and distance to subject . As distance or the size of the acc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Back-illuminated Sensor
Comparison of simplified back-illuminated and front-illuminated pixel cross-sections A back-illuminated (BI) sensor, also known as back-side illumination (BSI) sensor, is a type of digital image sensor that uses a novel arrangement of the imaging elements to increase the amount of light captured and thereby improve low-light performance. The technique was used for some time in specialized roles like low-light security cameras and astronomy sensors, but was complex to build and required further refinement to become widely used. Sony was the first to reduce these problems and their costs sufficiently to introduce a 5-megapixel 1.75 μm BI CMOS sensor at general consumer prices in 2009.''Sony'', 2009 BI sensors from OmniVision Technologies have since been used in consumer electronics from other manufacturers as in the HTC EVO 4G Android smartphone, and as a major selling point for the camera in Apple's iPhone 4.''Apple'', 2010 Description A traditional, front-illuminated di ...

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] |
Gorilla Glass
Gorilla Glass is a brand of chemically strengthened glass developed and manufactured by Corning Inc. Currently in its ninth generation, it is designed to be thin, light, and damage-resistant. Its surface strength and crack-resistance are achieved through immersion in a hot potassium-salt ion-exchange bath. The alkali- aluminosilicate sheet glass is primarily used as cover glass for portable electronic devices, including smartphones, smartwatches, portable media players, portable computer displays, and television screens. It is manufactured in Harrodsburg, Kentucky; Asan, South Korea; and Taiwan. As of October 2017, Gorilla Glass was used in approximately five billion devices worldwide. Despite its market dominance, Gorilla Glass faces competition from similar products, including AGC Inc.'s Dragontrail, Schott AG's Xensation, and synthetic sapphire. Background and development Corning experimented with chemically strengthened glass in 1960 as part of a "Project Muscle" in ...

Corning Inc
Corning Incorporated is an American multinational technology company specializing in glass, ceramics, and related materials and technologies including advanced optics, primarily for industrial and scientific applications. The company was named Corning Glass Works until 1989. Corning divested its consumer product lines (including CorningWare and Visions Pyroceram-based cookware, Corelle Vitrelle tableware, and Pyrex glass bakeware) in 1998 by selling the Corning Consumer Products Company subsidiary (later Corelle Brands) to Borden. , Corning had five major business sectors: display technologies, environmental technologies, life sciences, optical communications, and specialty materials. Corning is involved in two joint ventures: Dow Corning and Pittsburgh Corning. The company completed the corporate spin-offs of Quest Diagnostics and Covance (now Fortrea) in January 1997. Corning is one of the main suppliers to Apple Inc. Since working with Steve Jobs in 2007, to develop t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pixel Density
Pixels per inch (ppi) and pixels per centimetre (ppcm or pixels/cm) are measurements of the pixel density of an electronic image device, such as a computer monitor or television display, or image digitizing device such as a camera or image scanner. Horizontal and vertical density are usually the same, as most devices have square pixels, but differ on devices that have non-square pixels. Pixel density is not the same as where the former describes the amount of detail on a physical surface or device, the latter describes the amount of pixel information regardless of its scale. Considered in another way, a pixel has no inherent size or unit (a pixel is actually a sample), but when it is printed, displayed, or scanned, then the pixel has both a physical size (dimension) and a pixel density (ppi). Basic principles Since most digital hardware devices use dots or pixels, the size of the media (in inches) and the number of pixels (or dots) are directly related by the 'pixels per inch ...

Pixels
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest addressable element in a dot matrix display device. In most digital display devices, pixels are the smallest element that can be manipulated through software. Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black. In some contexts (such as descriptions of camera sensors), ''pixel'' refers to a single scalar element of a multi-component representation (called a ''photosite'' in the camera sensor context, although ''sensel'' is sometimes used), while in yet other contexts (like MRI) it may refer to a set of component intensities for a spatial position.
