Super CCD
Super CCD is a proprietary charge-coupled device that has been developed by Fujifilm since 1999. The Super CCD uses octagonal, rather than rectangular, pixels. This allows a higher horizontal and vertical resolution (at the expense of diagonal resolution) to be achieved than a traditional sensor of an equivalent pixel count. On January 21, 2003 Fujifilm announced the fourth generation of SuperCCD sensors, in two variations: SuperCCD HR and SuperCCD SR. HR stands for "high resolution" and SR stands for "super dynamic range". The SR sensor has two photodiodes per photosite, one much larger than the other. Appropriately processing information from both can yield larger black to white range of brightness (dynamic range). The 4th Generation Super CCD HR has sensors placed at 45 degrees to the horizontal. In order to convert the images into the normal horizontal/vertical pixel orientation, it interpolates one pixel between each pair of sensors, thereby producing 12 recorded megapixels ...

TrustedReviews
''Trusted Reviews'' is a web publication focused on technology, published in London, UK by Incisive Media. History Trusted Reviews was founded in 2003 by Hugh Chappell and Riyad Emeran as a response to the decline in sales of computer reviews magazines. Launched to provide a web only product for increasingly internet-literate users, access was deliberately made free to compete with paid-for magazine subscriptions. The website covers the consumer technology market, focusing on mobile phones, TV and audio visual equipment and computing. In 2007, the-then IPC Media bought Trusted Reviews in order to expand its digital operations. In 2010, Cliff Jones was appointed editor of Trusted Reviews. In 2012, Evan Kypreos was appointed editor. In 2018, Nick Merritt was appointed Editor-in-Chief. Prior to Meredith purchasing Time Inc., Trusted Reviews was regularly featured as a contributor to Time Magazine. In 2020, Future plc acquired TI Media, the then-parent company of Trusted R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charge-coupled Device
A charge-coupled device (CCD) is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a major technology used in digital imaging. In a CCD image sensor, pixels are represented by p-doped metal–oxide–semiconductor (MOS) capacitors. These MOS capacitors, the basic building blocks of a CCD, are biased above the threshold for inversion when image acquisition begins, allowing the conversion of incoming photons into electron charges at the semiconductor-oxide interface; the CCD is then used to read out these charges. Although CCDs are not the only technology to allow for light detection, CCD image sensors are widely used in professional, medical, and scientific applications where high-quality image data are required. In applications with less exacting quality demands, such as consumer and professional digital cameras, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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-sensi ...

CMOS Sensor
An active-pixel sensor (APS) is an image sensor where each pixel sensor unit cell has a photodetector (typically a pinned photodiode) and one or more active transistors. In a metal–oxide–semiconductor (MOS) active-pixel sensor, MOS field-effect transistors (MOSFETs) are used as amplifiers. There are different types of APS, including the early NMOS APS and the now much more common complementary MOS (CMOS) APS, also known as the CMOS sensor. CMOS sensors are used in digital camera technologies such as cell phone cameras, web cameras, most modern digital pocket cameras, most digital single-lens reflex cameras (DSLRs), and mirrorless interchangeable-lens cameras (MILCs). CMOS sensors emerged as an alternative to charge-coupled device (CCD) image sensors and eventually outsold them by the mid-2000s decade. The term ''active pixel sensor'' is also used to refer to the individual pixel sensor itself, as opposed to the image sensor. In this case, the image sensor is sometimes ...

DSLR
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. ...

S200EXR
The Fujifilm FinePix S200EXR (also known as S205EXR) is a digital bridge camera from Fujifilm introduced in July 2009. It features a 12 Megapixel, 1/1.6" EXR sensor, Fujifilm's 9th generation of Super CCD, first seen in F200EXR, and uses same body and lens as FinePix S100fs. The main features of the EXR sensor is the new color filter, different from largely used Bayer filter, and pixel binning capability, which it uses to produce higher dynamic range and better sensitivity. Due to the nature of EXR technology, high sensitivity (SN) and high dynamic range (DR) modes produce 6 Megapixel 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 sm ... resolution images. The S200EXR has the shape and size to a small DSLR, but with a fixed lens. However, unlike a DSLR, the S200EXR features an 0 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fujifilm FinePix F-series
The Fujifilm FinePix F series is a line of compact digital cameras that was known for its low-light performance in 2005, with relatively low image noise and natural colors even at high ISO settings. With its relatively large, but moderate resolution Super CCD sensors, it concentrated on image quality, and low-light shooting without flash, which was mostly restricted to prosumer models at the time. Image comparisons show that Fujifilm's sixth-generation, 6.3-megapixel Super CCD sensor (used on F10/F20/F30/F31 models) set the benchmark for low-noise, high ISO performance among point-and-shoot cameras and has not yet been matched by any of Fuji's higher megapixel Super CCD sensors. The Fujifilm FinePix F200EXR (February 2009) has low light capabilities similar to the F31fd in pixel binning mode, but allows for double the resolution in good light. However, at the same focal length the lens of the F200EXR is about 1/2 stop slower than that of the F31fd. The key feature of the F200 ...
