Samsung, Google, and Apple are in three-way fight when it comes to photography, but among the three, Samsung is usually The most upcoming With the new progress in your sensor technology. This recently Published a deep dive in your nanoprism techniqueA new type of microles that say that it significantly improves light aggregation.
Oversimplim, a sensor can collect as light, better photos. This basic principle becomes more difficult because sensors and pixels become smaller. On smartphones, where sensors are incredibly smaller than standalone cameras, getting light to Pixel is a challenge.
“Technology smartphone has developed towards making the pixel small and smaller to feel high-resolution images without increasing the size of the camera module. However, it has gradually reduced the sensitivity of the unit pixel and the image quality caused by the crossstock between the pixel caused the image quality. By Image sensor world,
All smartphone makers have chosen to deal with the problem of poorly low-light photos in different ways, software and algorithm is the most popular approach-even for Samsung. But the company is implementing a concept proposed earlier in 2017: nanoprism.
Each pixel on a sensor is accompanied by a microllenge that focuses the light on the pixel. The better the microlyns, the better the mild gathering capacity of each pixel, and therefore better quality final image. It is easy for large pixels to manufacture microles, but as the pixel becomes smaller, becomes more and more difficult to make microlns and control.
“In the existing microles-based optics, the color filters of the microllenge and pixels match 1: 1, so the color of each pixel can only be accepted by the pixel corresponding to the color filter.
Nanoprism technique changes the design of those microlines so that instead of a standard round lens, the pixel microllenge is accompanied by a nanoscale structure in the position, which directs each color-to-sequel to the pixel.
“Simply put, the amount of light obtained by each pixel is increased, as the color can be sent to adjacent pixels using the refraction and spread of light lost due to color mismatch.”
The replacing a microllan with a nanoprism allows the pixel to obtain more light. Samsung argues that this is a far better solution than the current method, but if it is, then why have it taken eight years to implement it?
“The commercialization of the meta-photonics technique in the image sensor was a challenging task,” says Samsung. “As it can be estimated by nanoprism by its name, it was especially difficult from the development of the process to mass production because the precise and complex nanometer (NM) structures were to be implemented in the pixel. To bring new technology to life, special techniques and methods were introduced, in which CMP (chemical mechanical polishing) and low-temperature processes (chemical mechanical polishing) and low-temperature procedures were introduced. Disforn.
The commercial implementation of nanoprism technology is called the Iscell JNP, which went into large -scale production this year and is already included in the “recent smartphone”. Samsung did not say that smartphone or which camera system is found in Isocell JNP, but it says where it is used, sensitivity increases by 25% compared to the previous sensor, with the same specifications, but using pre -microlance technology.
