Fujifilm X-A2
The Fujifilm X-A2 is a rangefinder-styled digital mirrorless camera announced by Fujifilm on January 15, 2015, and released in the UK on March 1, 2015. Features The Fujifilm X-A2 is the first X-mount camera with a 175° LCD screen. It is aimed at the growing selfie market, with new face detection and eye detection autofocus modes, for sharper results when taking Self portraits. It was also among the one of the first of the X-mount line up to have the new Chrome film simulation as a preset The Fujifilm X-A2 sports a regular Bayer filter sensor array, as opposed to the X-Trans sensor that is typical among the X-mount camera system. The camera was designed in such a way that it could be used one handed, so all of the most used settings are within reach when using the camera in selfie mode. Key Features * 16.3 Megapixels In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest point in an ...

Fujifilm X-mount
The Fujifilm X-mount is a type of interchangeable lens mount designed by Fujifilm for use in those cameras in their X-series line that have interchangeable-lenses. These lenses are designed for 23.6mm x 15.6mm APS-C sensors. Various lens manufacturers use this mount, such as Fujifilm's own XF and XC lenses, Carl Zeiss AG (Touit lenses), Samyang Optics, Handevision, SLR Magic, Viltrox and Zhongyi Optics. Additionally, a host of adapters for a range of SLR lenses are available, allowing the mounting of lenses (without autofocus or auto aperture) from Canon, Nikon, Pentax, Minolta, Contax/Yashica, Konica and more. This mount type should not be confused with the discontinued Fujica X-mount, which is not compatible with the newer X-mount without an adapter.

LCD Screen
A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly but instead use a backlight or reflector to produce images in color or monochrome. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images with low information content, which can be displayed or hidden. For instance: preset words, digits, and seven-segment displays, as in a digital clock, are all good examples of devices with these displays. They use the same basic technology, except that arbitrary images are made from a matrix of small pixels, while other displays have larger elements. LCDs can either be normally on (positive) or off (negative), depending on the polarizer arrangement. For example, a character positive LCD with a backlight will have black lettering on a background that is the col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Selfie
A selfie () is a self-portrait photograph, typically taken with a digital camera or smartphone, which may be held in the hand or supported by a selfie stick. Selfies are often shared on social media, via social networking services such as Facebook, Twitter, Snapchat, and Instagram. They are often casual in nature (or made to appear casual). A "Selfie" typically refers to self-portrait photos that are taken with the camera held at arm's length, as opposed to those taken by using a self-timer or remote. A selfie, however, may include multiple subjects however; as long as the photo is being taken by one of the subjects featured, it is considered a selfie. However, some other terms for selfies with multiple people include usie, groufie, and wefie. Alternatively, one can take a mirror selfie, with the camera pointed at a mirror instead of directly at one's face, often to get a full-body shot. Etymology "Selfie" is an example of hypocorism – a type of word formation th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Face Detection
Face detection is a computer technology being used in a variety of applications that identifies human faces in digital images. Face detection also refers to the psychological process by which humans locate and attend to faces in a visual scene. Definition and related algorithms Face detection can be regarded as a specific case of object-class detection. In object-class detection, the task is to find the locations and sizes of all objects in an image that belong to a given class. Examples include upper torsos, pedestrians, and cars. Face detection simply answers two question, 1. are there any human faces in the collected images or video? 2. where is the located? Face-detection algorithms focus on the detection of frontal human faces. It is analogous to image detection in which the image of a person is matched bit by bit. Image matches with the image stores in database. Any facial feature changes in the database will invalidate the matching process. A reliable face-detection ...

Autofocus
An autofocus (or 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 accuracy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self Portrait
A self-portrait is a representation of an artist that is drawn, painted, photographed, or sculpted by that artist. Although self-portraits have been made since the earliest times, it is not until the Early Renaissance in the mid-15th century that artists can be frequently identified depicting themselves as either the main subject, or as important characters in their work. With better and cheaper mirrors, and the advent of the panel painting, panel portrait, many painters, sculptors and printmakers tried some form of self-portraiture. ''Portrait of a Man in a Turban'' by Jan van Eyck of 1433 may well be the earliest known panel self-portrait. He painted a separate portrait of his wife, and he belonged to the social group that had begun to commission portraits, already more common among wealthy Netherlanders than south of the Alps. The genre is venerable, but not until the Renaissance, with increased wealth and interest in the individual as a subject, did it become truly popular.

Bayer Filter
A Bayer filter mosaic is a color filter array (CFA) for arranging RGB color filters on a square grid of photosensors. Its particular arrangement of color filters is used in most single-chip digital image sensors used in digital cameras, camcorders, and scanners to create a color image. The filter pattern is half green, one quarter red and one quarter blue, hence is also called BGGR, RGBG, GRBG, or RGGB. It is named after its inventor, Bryce Bayer of Eastman Kodak. Bayer is also known for his recursively defined matrix used in ordered dithering. Alternatives to the Bayer filter include both various modifications of colors and arrangement and completely different technologies, such as color co-site sampling, the Foveon X3 sensor, the dichroic mirrors or a transparent diffractive-filter array. Explanation Bryce Bayer's patent (U.S. Patent No. 3,971,065) in 1976 called the green photosensors ''luminance-sensitive elements'' and the red and blue ones ''chrominance-sensitive ...

X-Trans
The Fujifilm X-Trans is a sensor developed by Fujifilm and used in its Fujifilm X series cameras. Unlike most sensors featuring a conventional Bayer filter array, X-Trans sensors have a unique 6 by 6 pattern of photosites. Fujifilm claims that this layout can minimise moiré effects, and in turn increase resolution by eliminating the need for a low-pass filter. Details Typical Bayer sensor arrays have RGB photosites in a repeated 2 by 2 pattern. When it overlaps with a regular pattern that is being captured, a new interference pattern can occur that does not exist in real life. In contrast, X-Trans sensors have a more randomised pattern of RGB photosites than conventional Bayer array sensors, reducing the likelihood of interference and removing a need for a low-pass filter that lowers image resolution. See U.S. Patent 8,531,563. Conventional Bayer sensors can also produce false colour as they do not have R and B photosites in some horizontal and vertical lines, Fujifilm claims t ...

Megapixels
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest point in an all points addressable 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.
