Hello and welcome..Over the past decade, the performance of smartphonecamera has improved immensely,.changing the way we take pictures forever..To make mobile image sensor even better thanit already is,.Samsung continues to push innovation through’higher resolutions’ and ‘multiple cameras’..Today I’m proud to introduce ISOCELL JN1,.the industry’s first mass produced 50MP image sensor.with 0.64μm pixels..Up until now, the ultra-high resolution wasexclusive to flagships and high-end smartphones..However, this new breakthrough in micro-sizedpixel technology will allow more people to.experience awesome details..And now, without further ado, here is ISOCELL JN1,.the image sensor built for awesome cameraseverywhere..Hello everyone..Thank you for joining us today..Before we dive further into our latest innovation,I’d liked to quickly go over what image sensor.is and what Samsung has achieved so far..Image sensor is very similar to our eyes..well, retina in our eyes, to be more exact..Like the retina which converts the light receivedinto neural signals for our brain, image sensor.converts the light into digital signals and thensends it over to a mobile processor..Samsung released its first image sensors in2002, almost twenty years ago..And since then Samsung has continuously beenat the forefront, pulling the industry forward..The year 2019 was a quite a memorable year for Samsung.as we’ve achieved two technical breakthroughs in mobile image sensor..The industry’s highest resolution at 108MP,.and the industry’s smallest pixel size at 0.7μm..Why is this important?.Well because the two achievements show ourability to integrate more number of pixels.while keeping the sensor small enough to fit in a slim device..Even after we have hit our big milestone wecontinued forward and broke our own record again.with ISOCELL JN1, the industry’s firstmanufactured 0.64μm image sensor..Thank you Ran for going over the ISOCELL’spath of innovation..Now let’s go through some key details of thenew JN1..Recently, more and more smartphones in the high to low range are replacing 8 to 12Mp with super high resolution cameras.making 32 to 48MP the new norm..To meet this new demand for small-sized imagesensor with high resolution,.ISOCELL JN1 was designed early on with 0.64μm pixels..With 50 million pixels packed in 1/2.76 inchoptical format size, JN1 is arguably the smallest.50 mega-pixel sensor available today..And this makes it highly unique and beneficial in its own way..Currently, 1/2.8 inch optical format sizeis the most widely used and preferred size.in mobile image sensors..This is because it is well suited for bothfront and rear-facing cameras and helps smartphone.design to stay slim and sleek..At 1/2.76 inch, JN1 is fully compatible with 1/2.8 inch in size.and can fully utilize its camera-related componentssuch as lens and module..This allows the device manufacturers to upgradecamera resolution on their devices to 50 mega-pixel with ease..JN1 does not just make the resolution betterbut it also make slimmer design possible..Due to its small size, JN1’s camera moduleheight can be reduced by around 10-percent,.when compared to a 48Mp sensor with 0.7μm pixels..Being compatible with 1/2.8 inch also makesJN1 a perfect choice for front-facing and all types of rear cameras.including wide, ultra-wide, and telephoto..Except for the main wide-camera, sub-camerasgenerally use 16Mp resolution.or lower sensors due to spacelimitations..But with JN1, even the sub-cameras can nowoffer higher resolution.delivering significant improvements such as 4K video at 60 frame per second.and high-zoom ratio without compromising the module height..With such high versatility,.ISOCELL JN1 allows the device manufacturers to save engineering and sourcing resources..But making a pixel smaller is a very challenging task..Image sensor needs to capture enough lightwith pixels that are approximately 100 times smaller.than the average thickness of a human hair..Samsung’s answer to this challenge is ISOCELL,.a pixel technology developed in 2013..’ISOCELL’ is a compound word made up of ‘Isolate’ or ‘ISO’,.the standard for light sensitivity, and ‘Cell’..ISOCELL adds a barrier around each and every pixel,.that brings both crosstalk reduction and charge storage capacity increase by up to 30% each..Recently, ISOCELL was upgraded to version 2.0..The first phase of ISOCELL 2.0 improved thepixel’s light sensitivity by around 15%..For JN1, an enhanced version of ISOCELL 2.0 wasapplied adding up to 16% more boost in sensitivity..For brighter and more vivid results, JN1 featuresTetrapixel technology..In day light or outdoors Tetrapixel reorganizesthe color filter array into a traditional RGB format.using a re-mosaic algorithm toproduce highly detailed images..In the evening or indoors, Tetrapixel mergesJN1’s four pixels to imitate single large 1.28μm pixel.for an incredible low light photography..For further improvement in picture quality,.ISOCELL JN1 comes with Smart-ISO..Smart-ISO intelligently selects between high and low ISO level.according to the illumination of the environment for optimal light-to-electric signal conversion..Generally speaking, many image sensors have high ISO as a single level of amplifier to help brighten up the images..While this may be sufficient in most cases,.amplifying the light signal received in a really bright setting may wash out details due to oversaturation..JN1 is able to save more essential detailsin bright settings by using low ISO,.and produce brighter results in the dark with high ISO..Smart-ISO also comes in handy when in a mixed-light environment..Smart-ISO simultaneously produce two differentreadouts, one using low and another with high ISO,.and merge them together via mobile processorto create more perfectly balanced high dynamic range image..Now let’s talk about autofocus..When taking pictures of your constantly movingpet or the fleeting precious moment,.there may be nothing more important than a fast auto focus..Phase detection autofocus or PDAF is one ofthe most popular auto focusing method.used in modern smart phones..Super PD is one of Samsung’s auto-focusingtechnologies..It has auto-focus optimized micro-lens overone out of thirty-two pixels to detect and.check the difference betweenleft and right phases to get in focus..For faster focus even in low-light, ISOCELLJN1 is equipped with upgraded Double Super PD technology..With twice the focusing agent density, DoubleSuper PD offers the same level of AF performance.as Super PD even with about 60% less illumination..To sum up, our new 50MP ISOCELL JN1 is thefirst of our upcoming new line-up of 0.64μm sensors..To capture and produce images in a most awesomeway possible, JN1 comes with various advanced.sensor technologies including Tetrapixel,Smart-ISO, and Double Super PD..Being compatible with popular 1/2.8 inch opticalformat size,.JN1 is our recommended choice for all kindsof rear and front facing cameras..ISOCELL JN1 is currently in mass productionand new smart phones powered by JN1 may become.available in the marketin the 2nd half of this year..And now,Let’s answer some of the questions we’ve received..Ok, here are the three most asked questions..First question,.(Q) Will we see ISOCELL JN1 in the next generation premium devices?.Miguel, how about you take this one?.A: Well, JN1 is a highly versatile solutionthat can be used for and fit into main, sub,.and even front cameras..So, yes, you may expect to see JN1 in premiumdevices for sub-cameras, but for main rear camera,.it may be unlikely as the sensor isgeared more toward the volume zone smart phones..Alright, next one is yours..Q: It’s great that 50Mp can snuggly fit intoa smartphone,.but wouldn’t ISOCELL JN1’s small 0.64μm pixel size affect the quality of photos?.A: Yes, pixel size does matter when it comesto quality of photos..But with large-sized pixels,.it’s almost impossible to increase the resolution as the space available for camera is limited..To deliver small-sized 50Mp image sensor with high color fidelity,.we haven’t just reduced the size of the pixelbut also significantly diminished optical loss,.improved light sensitivity, and reducednoise through advanced technologies.such as ISOCELL 2.0, Tetrapixel and Smart-ISO..Ok last one..Q: When can we expect the image sensor tohave human eye like resolution?.…hmm what do you think?.A: Well, ISOCELL’s ultimate goal is to bringhuman eye like resolution and quality to mobile phones..But at current pixel size,such high resolution would have huge camera bump.which would not be pleasing to see or to have..To achieve our goal, we will not only continueto bring innovations to pixel technology,.but also provide a total camera solution withCorephotonics for an amazing picture quality..Thanks Miguel..Well, I hope we’ve answered some of the questionsyou may have on ISOCELL..Thank you and happy snapping!.While we make advancements in ultra-smallpixel technology, we also offer products.in big pixel categoryas part of our two track strategy..Last February,we’ve unveiled our biggest 50MP sensor ISOCELL GN2.with 1.4μm pixels, and today,ISOCELL JN1..Samsung has made amazing strides in sensorinnovation.and will continue to do so..We will be back soon with more 0.64μm sensorsthis year, so please stay tuned..Thank you and stay safe..
