CYGM Filter
In digital photography, the CYGM filter is an alternative color filter array to the Bayer filter (GRGB). It similarly uses a mosaic of pixel filters, of cyan, yellow, green and magenta, and so also requires demosaicing to produce a full-color image. Overview CYGM gives more accurate luminance information than the Bayer filter, hence a wider dynamic range, but at the expense of color accuracy. This is because the cyan and yellow components of the colour filter array do not produce a true monochromatic yellow or cyan but are rather modifications of the filters used to absorb 'color'. Under the conventional trichromatic theory, a 'green' measurement is taken by placing a color filter which absorbs 'red' and 'blue' in front of the light sensor. A 'blue' measurement is taken with a 'green' and 'red' absorbing filter, and a 'red' measurement with a 'blue' and 'green' absorbing filter. RGB is therefore derived by using filters which each absorb 2/3 of the spectrum for each measurement. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trichromacy
Trichromacy or trichromatism is the possessing of three independent channels for conveying color information, derived from the three different types of cone cells in the eye. Organisms with trichromacy are called trichromats. The normal explanation of trichromacy is that the organism's retina contains three types of color receptors (called cone cells in vertebrates) with different Absorption spectroscopy, absorption spectra. In actuality the number of such receptor types may be greater than three, since different types may be active at different light intensities. In vertebrates with three types of cone cells, at low light intensities the rod cells may contribute to color vision. Humans and other animals that are trichromats Humans and some other mammals have Evolution, evolved trichromacy based partly on pigments inherited from early vertebrates. In fish and birds, for example, Tetrachromacy, four pigments are used for vision. These extra cone receptor visual pigments detect ...

Foveon X3 Sensor
The Foveon X3 sensor is a digital camera image sensor designed by Foveon, Inc., (now part of Sigma Corporation) and manufactured by Dongbu Electronics. It uses an array of photosites that consist of three vertically stacked photodiodes. Each of the three stacked photodiodes has a different spectral sensitivity, allowing it to respond differently to different wavelengths. The signals from the three photodiodes are then processed as additive color data that are transformed to a standard RGB color space. The X3 sensor technology was first deployed in 2002 in the Sigma SD9 DSLR camera, and subsequently in the SD10, SD14, SD15, SD1 (including SD1 Merrill), the original mirrorless compact Sigma DP1 and Sigma DP2 in 2008 and 2009 respectively, the Sigma dp2 Quattro series from 2014, and the Sigma SD Quattro series from 2016. The development of the Foveon X3 technology is the subject of the 2005 book ''The Silicon Eye'' by George Gilder. Operation The diagram to the right depic ...

RGBE Filter
In digital photography, the RGBE filter is an alternative color filter array to the Bayer filter (GRGB). It similarly uses a mosaic of pixel filters, of red, green, blue and "emerald" ("like cyan" according to Sony), and so also requires demosaicing to produce a full-color image. It was developed by Sony and so far is used only in the ICX456 8-megapixel CCD and in the Sony Cyber-shot DSC-F828 camera. Sony states that the reason for adding the fourth filter color is "to reduce the color reproduction errors and to record natural images closer to the natural sight perception of the human eye". press release, DPReview.com, 15 July 2003. |
Color Filter Array
In digital imaging, a color filter array (CFA), or color filter mosaic (CFM), is a mosaic of tiny color filters placed over the pixel sensors of an image sensor to capture color information. The term is also used in reference to e paper devices where it means a mosaic of tiny color filters placed over the grey scale display panel to reproduce color images. Image sensor overview Color filters are needed because the typical photosensors detect light intensity with little or no wavelength specificity and therefore cannot separate color information. Since sensors are made of semiconductors, they obey solid-state physics. The color filters filter the light by wavelength range, such that the separate filtered intensities include information about the color of light. For example, the Bayer filter (shown by the image) gives information about the intensity of light in red, green, and blue (RGB) wavelength regions. The raw image data captured by the image sensor is then converted to a fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Canon PowerShot G1
The Canon PowerShot G is a series of digital cameras introduced by Canon in its PowerShot line in 2000. The G series cameras are Canon's flagship compact models aimed at photography enthusiasts desiring more flexibility than a point-and-shoot without the bulk of a digital single-lens reflex camera. The G series has a lithium-ion battery, full manual exposure control, an articulated LCD screen (G7, G9, G10, G15, and G16 have a fixed screen), Raw image format capture (all models except G7), a lens with a wider maximum aperture than standard PowerShot models, remote capture (except G11), and faster image processing. The range also includes a hot shoe (except G7 X and G9 X) for an external flashgun, including Canon's EX range. New models in the series have larger sensors than most other point-and-shoot cameras ( G1X, G1X Mark II, G7X). Main specifications G1 to G6 Common features across the early G series were: * A fast lens (minimum F number of 2.0). * A flip out and twist LCD, ...

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, act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
