Apple filed a patent for a new type of image sensor, which can give future iPhone and other Apple devices the opportunity to shoot photos and videos with dynamic levels of the range approaching human levels. />
a patent, called the “image sensor with pixels folded with a high dynamic range and low noise level” was first discovered by Y.M.Cinema magazine and describes the advanced architecture of the sensor, which combines the folded silicon, multiple levels of light capture and the mechanisms of noise suppression on the chip to reach up to 20 stacks of dynamic dynamic stopes range. About 20-30 stops, depending on how it corrects the pupil and how light is processed over time. Most smartphone cameras today make from 10 to 13 stops. If the proposed Apple sensor reaches its potential, it will not only surpass current iPhone, but also surpass many professional cinema cameras, such as Arri Alexa 35. The upper layer called the sensor contains details that capture light. The layer under it logic dies, processes processing, including noise reduction and exposure control.
Currently, Apple uses sensors made by Sony in the iPhone line. These sensors also use a two -layer design, but the Apple version includes several original functions and takes up less space. This allows each pixel in the sensor to store various amounts of light, depending on how bright scene is all in one image. At the same time, the sensor can cope with extremely wide differences in lighting, such as a person standing in front of a bright window, without losing detail in the shade or glare. Each pixel has its own built -in memory scheme, which measures and cancels electronic noise associated with heat heat, in real time. This is done on the chip itself before the image is saved or edited by software.
Patent documents cannot be accepted as evidence of Apple's direct plans, but they indicate the fields of active research and interest for the company, as well as the fact that it considers the development for future devices.
