Front-facing Camera
A front-facing camera, commonly known as a selfie camera, is a common feature of cameras, mobile phones, smartphones, tablets, laptops, and some handheld video game consoles. While stand-alone cameras face forward, away from the operator, tablets, smartphones and similar mobile devices typically have a camera facing the operator to allow taking a self-portrait photograph or video while looking at the display of the device, usually showing a live preview of the image. These are called front-facing cameras and are important for videotelephony and the taking of selfies. Often, the preview image is by default a mirror image, which is more intuitive for most people; this default can be overridden, and in any case the recorded image is not reversed. History While not a dedicated front-facing camera, the Casio QV-10 digital camera featured a lens that rotated 180 degrees. Introduced in 1995 it was the first consumer digital camera with a color LCD display. This allowed for the use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pixel
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a Raster graphics, 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 Sampling (signal processing), sample of an original image; more samples typically provide more accurate representations of the original. The Intensity (physics), intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as RGB color model, red, green, and blue, or CMYK color model, 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 ''wikt:sensel, sensel'' is sometimes used), while in yet ...

Camera Features
A camera is an instrument used to capture and store images and videos, either digitally via an electronic image sensor, or chemically via a light-sensitive material such as photographic film. As a pivotal technology in the fields of photography and videography, cameras have played a significant role in the progression of visual arts, media, entertainment, surveillance, and scientific research. The invention of the camera dates back to the 19th century and has since evolved with advancements in technology, leading to a vast array of types and models in the 21st century. Cameras function through a combination of multiple mechanical components and principles. These include exposure control, which regulates the amount of light reaching the sensor or film; the lens, which focuses the light; the viewfinder, which allows the user to preview the scene; and the film or sensor, which captures the image. Several types of camera exist, each suited to specific uses and offering unique cap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NEC E616
The NEC e616 is a 3G mobile phone from NEC Corporation announced in October 2003 and released in early 2004. Rechargeable battery The e616 takes Lithium ion battery, Lithium ion batteries, which are available in different capacities: * 780 mA·h standard battery (always included) tested standby time in 3G network : 6–12 h depending on use of the phone * 1360 mA·h high capacity battery (sometimes included) tested standby time in 3G network : 12–24 h depending on use of the phone Usage notes Batteries should always be recharged in the recharger and not within the mobile phone. Recharging in the mobile takes longer and the standby time will be halved. The short standby time and recharging error may be caused by faulty firmware or a faulty 3G network. In addition the battery time can be increased by turning off the GPS and vibra call alert, and by turning down the backlight of the display. Testing has revealed that using the phone in 2G network will provide 3-4 time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cellular Network
A cellular network or mobile network is a telecommunications network where the link to and from end nodes is wireless network, wireless and the network is distributed over land areas called ''cells'', each served by at least one fixed-location transceiver (such as a base station). These base stations provide the cell with the network coverage which can be used for transmission of voice, data, and other types of content via radio waves. Each cell's coverage area is determined by factors such as the power of the transceiver, the terrain, and the frequency band being used. A cell typically uses a different set of frequencies from neighboring cells, to avoid interference and provide guaranteed service quality within each cell. When joined together, these cells provide radio coverage over a wide geographic area. This enables numerous Mobile device, devices, including mobile phones, Tablet computer, tablets, laptops equipped with mobile broadband modems, and Wearable technology, wea ...

Wireless communication (or just wireless, when the context allows) is the transfer of information (''telecommunication'') between two or more points without the use of an electrical conductor, optical fiber or other continuous guided transmission medium, medium for the transfer. The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth, or as far as millions of kilometers for NASA Deep Space Network, deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, Mobile phone, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio ''wireless technology'' include Global Positioning System, GPS units, garage door openers, wireless Mouse (computing), computer mouse, Keyboard (computing), keyboards and Headset (audio), headsets, headphones, radio receivers, satelli ...

Personal Handy-phone System
The Personal Handy-phone System (PHS), also known as the Personal Communication Telephone (PCT) in Thailand, and the Personal Access System (PAS) and commercially branded as ''Xiaolingtong'' () in China, was a mobile network system operating in the 1880–1930 MHz frequency band. In Japan, it was introduced as a low-cost wireless service with smaller coverage areas than standard cellular networks. Its affordability made it popular in China, Taiwan, and other parts of Asia, as both the handsets and network infrastructure were relatively inexpensive to maintain. Developed in the 1990s, PHS used a microcell architecture with low-power base stations covering . unlike conventional cellular networks that relied on large cell sites for extensive coverage, PHS’s design was better suited for dense urban environments and reduced infrastructure costs. PHS was overtaken in the marketplace by GSM (3G) and UMTS (4G), with the last retail network decommissioned in 2021 and the last commerci ...
