Alguns podem não acreditar, mas para muitos uma das características mais importantes em um smartphone é a câmera. Não importa se a pessoa gosta de tirar fotos de paisagens, comidas, pessoas ou apenas selfies para poder escolher o aparelho correto, é essencial entender bem esse assunto para não errar na hora da matéria, vamos esclarecer algumas dúvidas a respeito das especificações técnicas de câmera de celular que todos deveriam conhecer. Vamos abordar assuntos como megapixel, abertura, ISO, velocidade do obturador, sensor tamanho e tipo, estabilização de imagem, HDR, siglas HD, Full HD e 4K, formato RAW, lentes e foco. Você conhece mais algum termo que gostaria que explicássemos? Diz aí no campo dos comentários!MegapixelsEssa é a especificação mais conhecida e mal interpretada entre todos os aspectos técnicos de uma câmera. O número utilizado para representar os megapixels reflete a quantidade de pixels que a imagem que foi capturada vai megapixel é igual a um milhão de pixels. Portanto, 20 megapixels é o mesmo que 20 milhões de pixels. De um modo geral, quanto mais megapixels, melhor tende a ser o resultado final. Assim, é possível dar zoom ou recortar uma imagem sem comprometer muito a qualidade da é perfeitamente possível ter uma foto melhor de uma câmera de 12 megapixels do que uma produzida por uma câmera de 20 megapixels. Isso acontece porque há outros aspectos que veremos a seguir que determinam a qualidade final da abertura faz referência à quantidade de luz que a lente deixa entrar. Essa medida é expressada pela letra F e, quanto menor o seu valor, mais luz entra. A abertura também faz variar a profundidade de campo, possibilitando desfocar o fundo da imagem. Nesse caso, quanto menor a abertura, medida faz referência a quão sensível uma câmera é à luz disponível. Quando maior o número ISO, maior é a sensibilidade. Porém, um ISO alto resulta em ruído nas fotos, o que produz aquele efeito granulado. No geral, um ISO baixo é o ideal, mas isso depende muito da quantidade de luz disponível na do obturadorA velocidade do obturador define quanto tempo a câmera mantém a lente aberta para registrar uma foto. Quanto maior o tempo que o obturador se mantém aberto, maior é a quantidade de luz que entra. Porém, isso também torna a câmera mais vulnerável a tremidas e action cams, nas quais a velocidade de captura é importante, uma velocidade do obturador alta é o ideal. Em fotos noturnas de objetos parados, uma exposição mais longa vai produzir resultados do sensorO sensor de uma câmera é o componente responsável por capturar a imagem. Quanto maior o sensor, melhor tende a ser a foto capturada. É por causa dele que muitos celulares têm a câmera é importante saber que há dois tipos de sensores CCD e CMOS. Smartphones mais modernos usam sensores CMOS, que são mais caros e complexos. Além disso, os sensores podem ser fabricados por empresas diferentes, como Samsung, Sony ou de imagemA estabilização de imagem pode ser óptica ou eletrônica. A óptica, mais avançada e cara, coloca o sensor dentro de um conjunto que compensa os movimentos do celular. A eletrônica tenta corrigir a imagem com ajustes na velocidade do obturador. Portanto, um smartphone com estabilização óptica de imagem é melhor do que um presença do HDR, ou grande alcance dinâmico, ajuda a registrar imagens com intensidades de luz diferentes. Quando ativado, a câmera captura imagens com exposições diferentes da mesma cena e combina as fotos para criar a imagem certa. Esse recurso está presente em muitos celulares, especialmente os mais modernos, podendo ter nomes Full HD e 4KHD, Full HD e 4K são medidas de resolução, mas são usadas para descrever as capacidades de gravar vídeos. Assim como no caso dos megapixels, uma das vantagens em altas resoluções é a capacidade de dar zoom sem perder muita resolução. Porém, o ponto negativo é o espaço ocupado pelos arquivos de vídeo, que aumenta de acordo com a = 1280x720 pixelsFull HD =1920x1080 pixelsUltra HD 4K = 3840x2160 pixelsFormato RAWA maioria dos celulares salva as imagens em JPEG, mas alguns já suportam o formato RAW. Esse formato registra tudo o que o sensor vê, sendo ideal para fotógrafos profissionais. Imagens JPEG são otimizadas e comprimidas para ocupar menos espaço. O RAW também consegue identificar mais níveis de brilho, mas ocupa mais de ser um aspecto pouco divulgado pelas fabricantes, é bom saber se o aparelho possui um bom conjunto de lentes. Algumas empresas já informam detalhes como a quantidade e o tipo de lente utilizada na câmera. Por isso, é bom ficar focalizar um objeto, as câmeras de celulares se apoiam em dois métodos o foco por contraste e o foco laser. A detecção de contraste geralmente é mais lenta e menos precisa. Já o foco laser é mais rápido e produz fotos com maior nitidez......Essas são as principais especificações de câmera que você deve analisar ao escolher um celular. Já conhecia todas elas? Gostaria de sugerir mais algum aspecto a ser considerado? Deixe a sua opinião no campo dos comentários!Você conhece bem todas as especificações técnicas de uma câmera de celular?

Home> Smartphones by Brian Klug on February 22, 2013 504 PM EST Posted in Smartphones camera Android Mobile The Camera Module & CMOS Sensor Trends So after we have the lenses, what does that go into? Turns out there is some standardization, and that standardization for packaging is called a module. The module consists of of course our lens system, an IR filter, voice coil motor for focusing, and finally the CMOS and fanout ribbon cable. Fancy systems with OIS will contain a more complicated VCM and also a MEMS gyro somewhere in the module. Onto CMOS, which is of course the image sensor itself. Most smartphone CMOSes end up being between 1/4“ and 1/3” in optical format, which is pretty small. There are some outliers for sure, but at the high end this is by far the prevailing trend. Optical format is again something we need to go look at a table for or consult the manufacturer about. Front facing sensors are way smaller, unsurprisingly. The size of the CMOS in most smartphones has been relatively fixed because going to a larger sensor would necessitate a thicker optical system, thus the real trend to increase megapixels has been more of smaller pixels. The trend in pixel size has been pretty easy to follow, with each generation going to a different size pixel to drive megapixel counts up. The current generation of modern pixels is around microns square, basically any 13 MP smartphone is shipping microns, like the Optimus G, and interestingly enough others are using microns at 8 MP to drive thinner modules, like the thinner Optimus G option or Nexus 4. The previous generation of 8 MP sensors were using micron pixels, and before that at 5 MP we were talking or micron pixels. Those are pretty tiny pixels, and if you stop and think about a wave of very red light at around 700nm, we’re talking about waves with micron pixels, around 2 waves at microns, and so forth. There’s really not much smaller you can go, it doesn’t make sense to go smaller than one wave. There was a lot of talk about the difference between backside BSI and front side illumination FSI for systems as well. BSI images directly through silicon into the active region of the pixel, whereas FSI images through metal layers which incur reflections and a smaller area and thus loss of light. BSI has been around for a while in the industrial and scientific field for applications wanting the highest quantum efficiency conversion of photons to electrons, and while they were adopted in smartphone use to increase the sensitivity quantum efficiency of these pixels, there’s an even more important reason. With pixels this small in 2D profile eg x microns the actual geometry of a pixel began to look something like a long hallway, or very tall cylinder. The result would be quantum blur where a photon being imaged onto the surface of the pixel, converted to an electron, might not necessarily map to the appropriate active region underneath - it takes an almost random walk for some distance. In addition the numerical aperture of these pixels wouldn’t be nearly good enough for the systems they would be paired with. Around the time I received the One X and One S last year, I finally became curious about whether we could ever see nice bokeh blurry background with an F/ system and small pixels. While trapped on some flight somewhere, I finally got bored enough to go quantify what this would be, and a side effect of this was some question about whether an ideal, diffraction limited no aberrations, ideal, if we had perfect optics system could even resolve a spot the size of the pixels on these sensors. It turns out that we can’t, really. If we look at the airy disk diameter formed from a perfect diffraction limited HTC One X or S camera system the parameters I chose since at the time this was, and still is, the best system on paper, we get a spot size around microns. There’s some fudge factor here since interpolation takes place thanks to there being a bayer grid atop the CMOS that then is demosaiced, more on that later, so we’re close to being at around the right size, but obviously microns is just oversampling. Oh, and also here are some hyperfocal distance plots as a function of pixel size and F/ for the same system. It turns out that everything is in focus pretty close to your average smartphone, so you have to be petty close to the subject to get a nice bokeh effect. 88 88 people found this article helpful Sensors impact images more than you realize Updated on September 28, 2020 A Complementary Metal-Oxide Semiconductor CMOS image sensor is a type of image sensor technology inside some digital cameras. It consists of an integrated circuit that records an image. You can think of the image sensor as being similar to the film in an old film camera. The CMOS sensor consists of millions of pixel sensors, each of which includes a photodetector. As light enters the camera through the lens, it strikes the CMOS image sensor, which causes each photodetector to accumulate an electrical charge based on the amount of light that strikes it. The digital camera then converts the charge to a digital reading, which determines the strength of the light measured at each photodetector, as well as the color. The software used to display photos converts those readings into the individual pixels that make up the photo when displayed together. CMOS vs. CCD CMOS uses a slightly different technology from a Charged Coupled Device CCD—another type of image sensor found in digital cameras. More digital cameras are using CMOS technology than CCD because CMOS image sensors use less power and can transmit data faster than CCD. However, CMOS image sensors tend to cost more than CCD. And as image sensors have been increasing in the number of pixels they record, the ability of a CMOS image sensor to move the data faster on the chip and to other components of the camera has become more valuable. In the early days of digital cameras, the batteries were larger because the cameras were larger, and so the CCD's higher power consumption was not a huge concern. But as digital cameras shrunk in size, requiring smaller batteries, CMOS became the better option. Benefits of CMOS One area where CMOS really has an advantage over other image sensor technologies is in the tasks it is able to perform on a chip, rather than sending the image sensor data to the camera's firmware or software for processing. For example, a CMOS image sensor can perform noise reduction capabilities directly on the chip, which saves time when moving data inside the camera. The CMOS image sensor can also perform analog-to-digital conversion processes on the chip—something CCD image sensors cannot do. Some cameras will even perform autofocus work on the CMOS image sensor itself, which again improves the camera's overall performance speeds. Continued Improvements in CMOS As camera manufacturers have migrated toward CMOS technology for image sensors in cameras, more research has gone into the technology, resulting in even strong improvements. For example, while CCD image sensors used to be cheaper than CMOS to manufacture, the additional research focus on CMOS image sensors has allowed the cost of CMOS to continue to drop. One area where this emphasis on research has benefited CMOS is in low light technology. CMOS image sensors continue to show improvement in their ability to record images with decent results in low-light photography. The on-chip noise reduction capabilities of CMOS have steadily increased in recent years, further improving the ability of the CMOS image sensor to perform well in low light. Another recent improvement to CMOS was the introduction of back-illuminated image sensor technology. With this design, the wires that move data from the image sensor to the camera are moved from the front of the image sensor—where they can block some of the light striking the sensor—to the back. This help the CMOS image sensor perform better in low light, while retaining the chip's ability to move data at a high speed when compared with CCD image sensors. Thanks for letting us know! Get the Latest Tech News Delivered Every Day Subscribe In any digital camera, the sensor is the most important piece of equipment. Without it, we wouldn’t be able to capture any images with our digital cameras. In fact, if you search around the internet, you may notice how many people agree that the sensor is more important than for good reason. That’s because, if you look at how a smartphone camera works, the sensor is the most vital part of the whole what exactly is the sensor? How does it work? Does the size impact picture at all? In this article, I will answer these and other questions you may have regarding the smartphone camera you continue, I recommend you read my article on how smartphone cameras work just so that you have a bit of context around what happens in a phone’s camera before the light that enters the camera reaches the sensor. It might help you understand this article a bit this article will not cover mobile camera depth sensors also known as depth cameras. For that, you can read this article or learn about smartphone ToF cameras let’s jump right is the sensor?A smartphone camera image sensor is a device that takes the light that enters the camera through the lens and produces a digital image from it. The surface of a sensor contains millions of photosites also known as pixels which are responsible for capturing the light. The total number of these light-capturing elements is known as a sensor is similar to a film frame. Back in the early days of photography before digital cameras, people used to take photos on a roll of celluloid film. This film was coated with a special chemical that produced an image when it was exposed to digital photography took over, the old film system was done away with and replaced with an electronic device– the image sensor. When the camera shutter is activated, the sensor is exposed to light and captures it in its photosites until the shutter is duration for which the shutter remains activated is known as the shutter speed. The longer the shutter is activated, the more light the camera’s sensor can receive. This means your photos can come out looking bright even in low light ideal but there is a downside to messing around with the shutter speed you need to be aware of. Ignoring it can lead to blurry a side note When shooting at slow shutter speeds, it’s very important that you keep your phone steady by using a camera support system such as a tripod. Personally, the Joby range of tripods for mobile phones is one of my favourites because of their small size and versatility. Definitely worth checking default, smartphone sensors do not see colour. Cameras that produce colour images have a colour filter array placed over the photosites in order to reproduce the colour information in the final digital image. If you look closely at the image above, you will see the red, green, and blue of the play a big role in how a photo turns out in terms of size and quality. A big sensor can fit more and bigger photosites than a small one. That means a smartphone with a big sensor can produce photos of a quality good enough to print and of sensorsThere are two types of sensors that can be found in digital cameras the CCD and CMOS sensors. They’re both responsible for converting light into electric signals but they work CCD Charge-Coupled Device sensor is the more traditional sensor. It’s an analogue device that captures an image in one shot and converts it into one sequence of voltage. A CCD sensor performs well in low light and doesn’t suffer as much from digital noise as a CMOS because the CCD sensor is expensive and uses a lot of power, it is not as popular in smartphone cameras as the CMOS Complementary Metal-Oxide Semiconductor uses less power than CCD, which makes it ideal for mobile devices. This type of sensor doesn’t capture an entire image in a single instance but rather captures images in a scanning type of downside to this is an issue known as the rolling shutter effect, where the image gets skewed when the sensor tries to interpret a moving object. This is an issue that’s especially most problematic when recording almost universally use CMOS sensors. Very few use CCD these does the sensor work?The sensor as a device is made up of millions of light-catching cavities known as photosites sometimes referred to as pixels, which can be confusing. When the shutter is activated, these photosites capture light for as long as the sensor remains light photons that are captured by each photosite are interpreted as an electrical signal. The strength of this signal will vary depending on how many photons were captured by the best way to understand this to imagine each photosite/pixel as a bucket catching rainwater. The rain represents the light that enters the camera and is captured by the photosites. If the bucket is filled all the way up to the top, the camera’s processor determines that it’s a white pixel. If the bucket is empty, it’s a black pixel. Anything else in between will be a varied intensity of white, and grey? What about colour? This is where a colour filter array comes into colour filter arrayTo capture images in colour, something known as a colour filter array CFA is needed. There are different types of CFAs but the most common is the Bayer Filter Array. It consists of alternating rows of the three primary colours red, green, and the array is made up of green filters, while blue and red each take up a quarter each. The reason for this is because our eyes are naturally more sensitive to green light. So having more green filters on the CFA will produce images that look more natural to our colour filter covers one photosite and captures light that corresponds with its colour. In other words, the red filter allows red light to be captured, the green filter captures green light and the blue filter allows blue light in. Using the Bayer filter, digital cameras can only capture one primary colour in each photosite. The others are begs the question if a sensor only receives red, green, and blue colour information, how do digital images pixels have colour information such as yellow, purple, orange, magenta, or any other colour? This is done through an interpolation process known as the Bayer filter is an RGB mosaic, every pixel is missing colour information from the other two colours of the RGB colour combo. Demosaicing happens when the camera’s processor calculates the colour values missing in each pixel by calculating the colour values of neighbouring better understand this process, check out How A Smartphone Camera Processes An Image. This will give you better insight into how a mobile camera’s ISP image signal processor creates the final image you can view and camera sensor sizeThe size of the sensor is usually expressed in inches as a fraction such as 1/ or 1/3”. This might seem to indicate the diagonal measurement of the sensor but that is not the case, which can be a whole history behind why this method of measurement. It’s quite involved but it pretty much boils down to manufacturers trying to veer consumer attention away from how small the sensors actually were. If you want to do a deep dive into it, I found this post really phones have different size sensors but smartphone camera sensors are notoriously small. At some point, the average sensor size on popular high-end smartphone cameras from the likes of Apple and Samsung was 1/ But recent smartphone camera trends show the size going up, especially in phones with high megapixel phone that holds the record of having the largest sensor to date is the 2014 Panasonic Lumix CM1 that had a 1-inch sensor. In 2019, the biggest sensor was 1/ found on the Huawei P30 Pro and Mate 30 Pro. In 2020, the Huawei P40 Pro+ has the largest sensor on the market at 1/ with the biggest sensors of all timePhone ModelSensor sizePixel SizeMegapixelsRelease date1Panasonic Lumix CM11” PureView 8081/ P40 Pro +1/ 50MP20204Samsung Galaxy S20 Ultra1/ 108MP20205Xiaomi Mi 10 Pro1/ 108MP20206Motorola Edge+1/ 108MP2020 * Pixel size after pixel binningHow big is it compared to full-frame DSLRSmartphone camera sensors have definitely increased in size over the years, and indeed have reached some amazing heights but they still pale in comparison to full-frame sensors the likes of which are found in DSLR image sensors are 35mm in diameter, the same size as old school celluloid film. Hence the name full-frame. There are many smaller frame sensors known as crop sensors, and smartphone sensors are found at the tail end of the full-frame 35mm sensor measures 864mm2 while a 1/ smartphone sensor only measures 43mm2. That means the once-praised Huawei P30 Pro’s sensor, for example, is 20 times smaller than a full-frame DSLR sensor. That’s a lot!How does the size of a sensor impact photos?The size of the sensor definitely has a huge impact on the quality of the images that a camera can produce. It’s one of the important factors that contribute to what makes a mobile phone photo look the bigger the sensor, the bigger the photosites. Big photosites mean the sensor gets to capture more light. This is especially useful in situations where the lighting is poor. You’re less likely to have issues with digital noise depending on how big the photosites a big sensor can pack more megapixels. The more megapixels a smartphone camera has, the higher the resolution of its images will be. If you’re into printing large prints of your mobile photos, then this is a you can’t have it both ways. You can’t pack a lot of large photosites on a sensor, not on smartphone camera sensors at least. Due to the physical size of the sensor being fixed, the more pixels a camera has, the smaller they poses a challenge on mobile cameras. Because they’re so small in size, the photosites on a smartphone camera sensor are very tiny. This puts smartphone cameras at a disadvantage when it comes to how much light their sensors can photosites don’t perform well when there isn’t enough lighting. You’d have to increase the camera’s ISO by quite a bit to get the brightness of images captured on a sensor with small photosites to match that of an image from a sensor with larger looking to buy a new phone, a lot of people simply go for the phone with the most megapixel camera and believe it’s the best. And, honestly, there’s nothing wrong with even though having lots of megapixels can give you prints with fine detail, don’t fall for the smartphone companies’ marketing hype and believe more megapixels means a better quality camera. In reality, the truth about megapixels is something totally you’re about to buy a new smartphone and the main camera is your biggest priority, just be sure to also lookout for a phone that has a camera with a big sensor.
