ion in other projects wikimedia commons wikidata item appearance move to sidebar hide from wikipedia the free encyclopedia device that converts images into electronic signals image capture redirects here for the software see image capture an image sensor or imager is a sensor used for imaging it converts light into electrical signals small bursts of current in proportion to the light intensity the pattern of electrical signals conveys the information in the image image sensors are used in electronic imaging devices of both analog and digital types which include digital cameras camera modules camera phones optical mouse devices medical imaging equipment night vision equipment such as thermal imaging devices radar sonar and others as technology changes electronic and digital imaging tends to replace chemical and analog imaging the two main types of electronic image sensors are the charge coupled device ccd and the active pixel sensor cmos sensor both ccd and cmos sensors are based on metal oxide semiconductor mos technology with ccds based on mos capacitors and cmos sensors based on mosfet mos field effect transistor amplifiers analog sensors for invisible radiation tend to involve vacuum tubes of various kinds while digital sensors include flat panel detectors commonly an image sensor requires a lens to project images onto the image sensor so they can be captured as done in a camera image sensors that require no lens have been developed pixels in image sensors can be damaged by high power lasers 1 comparison between ccd and cmos sensors edit a micrograph of the corner of the photosensor array of a webcam digital camera image sensor upper left on the motherboard of a nikon coolpix l2 6 mp the two main types of digital image sensors are the charge coupled device ccd and the active pixel sensor cmos sensor fabricated in complementary mos cmos or n type mos nmos or live mos technologies both ccd and cmos sensors are based on the mos technology 2 with mos capacitors being the building blocks of a ccd 3 and mosfet amplifiers being the building blocks of a cmos sensor 4 5 cameras integrated in small consumer products generally use cmos sensors which are usually cheaper and have lower power consumption in battery powered devices than ccds 6 ccd sensors are used for high end broadcast quality video cameras and cmos sensors dominate in still photography and consumer goods where overall cost is a major concern both types of sensor accomplish the same task of capturing light and converting it into electrical signals each cell of a ccd image sensor is an analog device a pinned photodiode 7 when light strikes the chip it is held as a small electrical charge in each photodiode the charges in the line of pixels nearest to the one or more output amplifiers are amplified and output then each line of pixels shifts its charges one line closer to the amplifiers filling the empty line closest to the amplifiers this process is then repeated until all the lines of pixels have had their charge amplified and output 8 a cmos image sensor has an amplifier for each pixel compared to the few amplifiers of a ccd this results in less area for the capture of photons than a ccd but this problem has been overcome by using microlenses in front of each photodiode which focus light into the photodiode that would have otherwise hit the amplifier and not been detected 8 behind each microlens sits a color filter made of special colored photoresist some cmos imaging sensors also use back side illumination to increase the number of photons that hit the photodiode 9 cmos sensors can potentially be implemented with fewer components use less power and or provide faster readout than ccd sensors 10 they are also less vulnerable to static electricity discharges it is possible to replace the color filter with a meta lens or microscopic prisms in order to garner light of the same color across pixels and direct it to a single pixel this is known as color splitting 11 12 another design a hybrid ccd cmos architecture sold under the name scmos consists of cmos readout integrated circuits roics that are bump bonded to a ccd imaging substrate a technology that was developed for infrared staring arrays and has been adapted to silicon based detector technology 13 another approach is to utilize the very fine dimensions available in modern cmos technology to implement a ccd like structure entirely in cmos technology such structures can be achieved by separating individual poly silicon gates by a very small gap though still a product of research hybrid sensors can potentially harness the benefits of both ccd and cmos imagers 14 performance edit see also emva1288 there are many parameters that can be used to evaluate the performance of an image sensor including dynamic range signal to noise ratio and low light sensitivity for sensors of comparable types the signal to noise ratio and dynamic range improve as the size increases it is because in a given integration exposure time more photons hit the pixel with larger area exposure time control edit exposure time of image sensors is generally controlled by either a conventional mechanical shutter as in film cameras or by an electronic shutter electronic shuttering can be global in which case the entire image sensor area s accumulation of photoelectrons starts and stops simultaneously or rolling in which case the exposure interval of each row immediately precedes that row s readout in a process that rolls across the image frame typically from top to bottom in landscape format global electronic shuttering is less common as it requires storage circuits to hold charge from the end of the exposure interval until the readout process gets there typically a few milliseconds later 15 color separation edit bayer pattern on sensor foveon s scheme of vertical filtering for color sensing there are several main types of color image sensors differing by the type of color separation mechanism integral color sensors 16 use a color filter array fabricated on top of a single monochrome ccd or cmos image sensor the most common color filter array pattern the bayer pattern uses a checkerboard arrangement of two green pixels for each red and blue pixel although many other color filter patterns have been developed including patterns using cyan magenta yellow and white pixels 17 integral color sensors were initially manufactured by transferring colored dyes through photoresist windows onto a polymer receiving layer coated on top of a monochrome ccd sensor 18 modern color filters are manufactured by using photolithography to reposit special pigment colored photoresists onto the image sensor one color at a time 19 since each pixel provides only a single color such as green the missing color values such as red and blue for the pixel are interpolated using neighboring pixels 20 this processing is also referred to as demosaicing or de bayering some image sensors have a high pixel count but to offset their disadvantages such as low light sensitivity and dynamic range under normal shooting conditions they resort to pixel binning in which the sensor reads 4 or 9 adjacent pixels as one group and all groups have the same color filter color 21 foveon x3 sensor using an array of layered pixel sensors separating light via the inherent wavelength dependent absorption property of silicon such that every location senses all three color channels this method is similar to how color film for photography works 3ccd using three discrete image sensors with the color separation done by a dichroic prism the dichroic elements provide a sharper color separation thus improving color quality because each sensor is equally sensitive within its passband and at full resolution 3 ccd sensors produce better color quality and better low light performance 3 ccd sensors produce a full 4 4 4 signal which is preferred in television broadcasting video editing and chroma key visual effects specialty sensors edit infrared view of the orion nebula taken by eso s hawk i a cryogenic wide field imager 22 special sensors are used in various applications such as creation of multi spectral images video laryngoscopes gamma cameras flat panel detectors and other sensor arrays for x rays microbolometer arrays in thermography and other highly sensitive arrays for astronomy 23 while in general digital cameras use a flat sensor sony prototyped a curved sensor in 2014 to reduce eliminate petzval field curvature that occurs with a flat sensor use of a curved sensor allows a shorter and smaller diameter of the lens with reduced elements and components with greater aperture and reduced light fall off at the edge of the photo 24 lensless sensing edit lenses focus light onto a camera s sensor as an image lensless sensors substitute alternative optical components and computational technologies to form images for example a coded aperture zone platem or diffraction grating can replace the lens these systems can reduce manufacturing cost and allow thin optical path lengths as well as high light throughput and application across broader frequency ranges 25 history edit see also digital imaging early analog sensors for visible light were video camera tubes they date back to the 1930s and several types were developed up until the 1980s by the early 1990s they had been replaced by modern solid state ccd image sensors 26 the basis for modern solid state image sensors is mos technology 27 28 which originates from the invention of the mosfet by mohamed m atalla and dawon kahng at bell labs in 1959 29 later research on mos technology led to the development of solid state semiconductor image sensors including the charge coupled device ccd and later the active pixel sensor cmos sensor 27 28 the passive pixel sensor pps was the precursor to the active pixel sensor aps 5 a pps consists of passive pixels which are read out without amplification with each pixel consisting of a photodiode and a mosfet switch 30 it is a type of photodiode array with pixels containing a p n junction integrated capacitor and mosfets as selection transistors a photodiode array was proposed by g weckler in 1968 4 this was the basis for the pps 5 these early photodiode arrays were complex and impractical requiring selection transistors to be fabricated within each pixel along with on chip multiplexer circuits the noise of photodiode arrays was also a limitation to performance as the photodiode readout bus capacitance resulted in increased noise level correlated double sampling cds could also not be used with a photodiode array without external memory 4 in june 2022 samsung electronics announced that it had created a 200 million pixel image sensor the 200mp isocell hp3 has 0 56 micrometer pixels with samsung reporting that previous sensors had 0 64 micrometer pixels a 12 decrease since 2019 the new sensor contains 200 million pixels in a 1 by 1 4 inch 25 by 36 mm lens 31 charge coupled device edit main article charge coupled device the charge coupled device ccd was invented by willard s boyle and george e smith at bell labs in 1969 32 while researching mos technology they realized that an electric charge was the analogy of the magnetic bubble and that it could be stored on a tiny mos capacitor as it was fairly straightforward to fabricate a series of mos capacitors in a row they connected a suitable voltage to them so that the charge could be stepped along from one to the next 27 the ccd is a semiconductor circuit that was later used in the first digital video cameras for television broadcasting 33 early ccd sensors suffered from shutter lag this was largely resolved with the invention of the pinned photodiode ppd 5 it was invented by nobukazu teranishi hiromitsu shiraki and yasuo ishihara at nec in 1980 5 34 it was a photodetector structure with low lag low noise high quantum efficiency and low dark current 5 in 1987 the ppd began to be incorporated into most ccd devices becoming a fixture in consumer electronic video cameras and then digital still cameras since then the ppd has been used in nearly all ccd sensors and then cmos sensors 5 active pixel sensor edit main article active pixel sensor the nmos active pixel sensor aps was invented by olympus in japan during the mid 1980s this was enabled by advances in mos semiconductor device fabrication with mosfet scaling reaching smaller micron and then sub micron levels 4 35 the first nmos aps was fabricated by tsutomu nakamura s team at olympus in 1985 36 the cmos active pixel sensor cmos sensor was later improved by a group of scientists at the nasa jet propulsion laboratory in 1993 5 by 2007 sales of cmos sensors had surpassed ccd

image sensor it was a modified mos dynamic ram dram memory chip 38 mos image sensors are widely used in optical mouse technology the first optical mouse invented by richard f lyon at xerox in 1980 used a 5 μm nmos integrated circuit sensor chip 39 40 since the first commercial optical mouse the intellimouse introduced in 1999 most optical mouse devices use cmos sensors 41 in february 2018 researchers at dartmouth college announced a new image sensing technology that the researchers call qis for quanta image sensor instead of pixels qis chips have what the researchers call jots each jot can detect a single particle of light called a photon 42 it is possible to make a light field camera by using an image sensor with two layers of micro lenses one stacked on top of the other 43 44 45 each large microlens covers a cluster consisting of several small microlenses this way the image sensor captures one copy of the subject for every large microlens and each copy varies in perspective slightly capturing a light field the light field represents a three dimentional capture of light in the image which can be used to adjust the focal point of the image during image editing this way the subjects in the image can be separated from the background without green screen or rotoscopy by determining which objects are in focus 46 47 48 49 see also edit list of sensors used in digital cameras
