Ещё раз к вопросу о мегачипах.

1500py073По весне был рассказ Мегачипы – весеннее обострение, о чипах с площадью свыше 1000 квадратных миллиметров. А теперь посмотрим какой к зиме урожай собрался. Для декады компьютерной графики, вполне подходящая информация.
Вот как о этом с стороной в 20см мегачипе Canon пишет под спойлером можно прочитать.
The World's Largest Ultrahigh-Sensitivity CMOS Image Sensor
A certain level of light is required when shooting with a digital camera or camcorder, and without it, images cannot be captured due to insufficient sensitivity.
In the pursuit of further improving the sensitivity of imaging elements, Canon has embraced the challenge of achieving higher levels of sensitivity and larger element sizes while maintaining high-speed readout performance, and has succeeded in developing the world's largest class of CMOS image sensor measuring approximately 20 cm square. At present, the standard diameter of the silicon wafers on which CMOS sensors are fabricated is 12 inches (approx. 30 cm). As such, a 20-cm-square sensor is the largest size that can be manufactured based on these dimensions, and is equivalent to nearly 40 times the size of a 35 mm full-frame CMOS sensor.
Increasing the size of CMOS sensors entails overcoming such problems as distortion and transmission delays for the electrical signals converted from light. To resolve these issues, Canon not only made use of a parallel processing circuit, but also exercised ingenuity with the transfer method itself. As a result, the sensor makes possible the shooting of video at 60 frames per second with only 0.3 lux of illumination (approximately the same level of brightness as that generated by a full moon).
Possible applications for this ultrahigh-sensitivity CMOS sensor include the video recording of celestial objects in the night sky, nocturnal animal behavior and auroras, and use in nightwatch cameras.
When installed in the 105 cm Schmidt camera at the Kiso Observatory operated by the University of Tokyo's Institute of Astronomy, the ultrahigh-sensitivity sensor made possible the world's first video recording of meteors with an equivalent apparent magnitude of 10, a level so dark that image capture had not been possible until now. As a result, the sensor provided proof that the frequency with which faint meteors occurred coincided with theoretical estimates to date. By supporting more detailed recording and statistical analysis of meteors, the technology could lead to an increased understanding of the influence that meteors may have exerted on the development of life on Earth.
Съёмка при освещении 0.3 lux с частотой кадров 60 в секунду, позволило Токийскому университету в своей обсервотории фиксировать движение метеоритов с яркостью как у звёзд 10-й величины. Это достойно, но похоже цена пока фашистская у этого мегачипа, разве![[livejournal.com profile]](https://www.dreamwidth.org/img/external/lj-userinfo.gif)
eddy_em таким задником прибарахлится.
Вот продукт, для более простого народа, матрица 9х11 дюймов (примерно 18х28см) всего за 106 000 долларов США, почти халява, похоже наш агент Трамп выгнал производителей матриц для спутников и аэрофотосъёмки на мороз, и парни должны в новом году сами добывать себе пропитание.
размер пиксела имеет значение
матрица 9х11 дюймов
а разрешеие 12 Мп
Всё для качества без компромисов!
Подазреваю, что продукция LargeSense может оказаться более русской-народной, чем у Canon. Особливо для любителей при Луне снимать видео 4К, что впрочем и Canon с верхнего фото делать умеет.
