Fujifilm’s SuperCCD EXR Unveiled: Sensor Promises High Res, High Quality Imaging

Fujifilm ’s “ topnotch ccd ” technology ’s been about forquitea while , but with the Modern Super CCD EXR it looks like the main focal point is on ameliorate image quality . It ’s not going to signal an end to the stupid megapixel race , but the EXR detector has a new mosaic color filter placement , new pixel - binning method acting and completely new electronic charge ascendancy : these result in improved light predisposition with lower noise as well as a wider dynamic ambit . These should make up for the epitome timber problems because of the shrinkage of photo - junction rectifier sizes as megapixel count has go up … but we ’ll have to see some test shoot to see if the sensing element hold out up to its hope . mechanical press release below .

PHOTOKINA 2008 , COLOGNE , GERMANY , September 23 , 2008 -FUJIFILM Corporation , on the anniversary of 10 twelvemonth of FinePix camera , has evolve “ Super CCD EXR , ” a revolutionary unexampled sensor developed in the tight interest of high figure of speech quality . There is strong demand in the digital tv camera market to increase the numeral of pixels on a sensor , which , all too often , is used as a convenient yard measure for figure of speech calibre . While introducing first-class 12 - megapixel cameras such as the FinePix F50fd and the FinePix F100fd , Fujifilm has had dandy achiever in increase pixel density while at the same time controlling racket and optimizing predisposition . Fujifilm ’s effort to improve overall prototype quality , while at the same clip increasing detector resolution , has been coordinated under the program of ‘ Real Photo Technology . ’ ‘ Real Photo Technology ’ is bear out by the notion that experienced photographers , many brought up using famous reversal films like FUJICHROME Velvia or PROVIA , realise that true image quality is about a combining of many factors like look , hue , colour fidelity , dynamic range , asperity , and solution . It is well recognize that increasing the pixel count on a sensor really makes it more difficult to attain high sensitivity and wide active range . As the photodiode gets smaller , the trouble of increase noise , blooming and clipping gain . It is widely believed that ‘ high firmness ’ and ‘ eminent sensitiveness ’ are irreconcilable opposites , and impossible to optimize on the same sensor , especially for thick cameras , where sensors are needs smaller . High calibre pictures are dependent on the topic . fantabulous low scant word-painting need high sensitivity ; high-pitched contrast picture show ask extensive dynamic range , while okay details , like the folio of a Sir Herbert Beerbohm Tree or strands of a modeling ’s hair , depend on high resolving . Fujifilm engineers set about the chore of building a pliant sensor to match the demand of the photographer . The end - goal is to bring on a sensing element that works as close to that of the human oculus as potential . Whatever nuance of color or sensitivity of timber that makes the scene so special to the photographer should be the continual challenge of the sensor engineer . The EXR sensor is fundamentally a switchable sensing element ; change its complex electronic behaviour to suit the subject , changing its characteristics as the photographer demands , and producing the very best ikon without urinate compromise . “ Super CCD EXR ” is the latest new generation of Super CCD to be produced by Fujifilm . Over the years , Fujifilm has excelled in gamy resolving power sensors through ‘ HR ’ technology ( F50fd , F100fd ) and high-pitched sensitiveness / all-embracing dynamic range through ‘ SR ’ detector ( S3 Pro , S5 Pro ) . The direction in the futurity will be to aggregate HR and SR applied science together to grow one universal detector suitable for all high lineament photography . The Technology of Super CCD EXR Super CCD EXR offer three principal changes from premature Fujifilm sensors : 1 . A new organisation of the mosaic colour filter 2 . A raw method of pixel bin 3 . A double-dyed revision of the electronic charge control 1 . EXR : ‘ Pixel Fusion Technology ’ for High Sensitivity and Low Noise Boosting sensitivity by increasing addition causes the coevals of random increased haphazardness , and conventional efforts to control this dissonance have resulted in blur images and loss of resolution . On the other hired hand , a low - noise signal can be obtained by pixel binning . However , the conventional approach to bin ( along the horizontal and vertical bloc ) generates fictive colors because of the separation of pixels of the same color . Because it is necessary to suppress this phenomenon , the result is a pregnant drop in sharpness . EXR changes the color filter arrangement . Two side - by - side , same - colored picture element are take together as a single picture element . With this design , the domain of imaging elements is doubled , the sensitivity is twice the normal level , and ‘ dark noise ’ is extremely small . Therefore it is potential to create a high sensitivity mental image with small noise , or else of increase the profit from a single pixel and increasing the disturbance . Another job with traditional pixel binning is the length between same - biased pixels . Since the pixels are combined vertically or horizontally , the distance between combined same - color pixels is magnanimous , resulting in the coevals of sour vividness . boast a new engineering called Close Incline Pixel Coupling , the newfangled Super CCD EXR can forbid the generation of put on colors by mixing two adjoining pixels as one , and deal to achieve both broken noise and excellent sharpness . 2 . EXR : ‘ Dual Capture Technology ’ for wide-eyed active Range Super CCD EXR use flexible and gamey - preciseness exposure control to at the same time get two image of the same prospect : one take at high sensitivity and the other at low sensitiveness . It then coalesce the two images to generate a pic that has excellent depth and range . Previously , Fujifilm used two unlike method acting to better dynamic grasp . The first was Super CCD SR . Through the acceptation of a “ double pixel anatomical structure ” based on silverish halide film , which comprises an “ S pixel ” with a great domain and gamy sensitiveness and an “ radius pixel ” with a small-scale area , a dynamic range four metre that of schematic sensing element was reach . The second was based on Super CCD HR , where the step of shadows was gradually line up while raising the predisposition of sign processing , and where highlights were softened to trace an optimal curve . like to Super CCD SR , the fresh EXR sensor employ Dual Exposure Control to pass on two differing sensitivities by controlling the light vulnerability clock time ( the time in which bang accumulates ) . Unlike SR , the imaging elements are the same ( big ) size , which intend the voltage for widened dynamical mountain chain is even bully , and facilitates a gravid spectrum of calibrated expression . 3 . EXR : ‘ o.k. Capture Technology ’ for High Resolution The classifiable complex body part of the new Super CCD EXR fully exploit all the pixels in the bed beneath the new gloss filter matrix and takes advantage of the optimise sign processing of the raw RP C.P.U. to create an image with the high potential resolution quality . Even though the detector has been designed for ‘ Dual Capture ’ for wide of the mark Dynamic Range and ‘ Pixel Fusion ’ for Low Noise , it actually performs as well as former 12 - megapixel Super CCD detector due to the Modern filter and photodiode conception . When light is full and even , and when fine detail is required , EXR can fork out exquisite detailed expression for landscape painting or architectural photography , and render the hunky-dory detail of clothes , hair or jewelry in portrayal picture taking . EXR : The Future Fujifilm is determined to habituate 10 of imaging know - how clear through the evolution of film to push the boundaries of what is potential to reach with an visualize sensor . The market for digital cameras is only around a decade older , and Fujifilm believe that it is potential to follow the holy Sangraal of ‘ infrangible image lineament ’ in the knowledge domain of electronic imaging , just as it did with schematic imaging . With EXR , Fujifilm can take one engineering science direction , rather than developing freestanding sensing element for in high spirits sensitivity and high result . Fujifilm looks forrader with excitement to introducing this sensor into its range of mellow timber cameras , and anticipate enthusiasts to see a quantum spring in image quality from anything they have view before .
