Smartphone manufacturers are constantly working on ways to improve the light sensitivity of their cameras for better-exposed photos at night.
The only problem is that the high number of megapixels – which provide sharper photos – often goes against this lens As the more megapixels, the smaller the pixels are on the image sensor, the less space means less light captured by each pixel.
That's what makes the latest Sony news so interesting. 48 megapixel image sensor, called IMX586, it's the largest number of megapixels we've ever seen in a sensor developed for mobile devices, but Sony is adamant that it will not be done not at the expense of performance in dark conditions.

Moreover, as Sony provides the majority of the phone makers with the sensors that are behind their goals, there is a very good change that the IMX586 could power the camera in your future handset. The IMX586 is not the first image sensor to promise paradoxically sharper and brighter images. The triple camera Huawei P20 Pro implemented a 40 megapixel main sensor next to a monochrome sensor of 20 MP and another 8 MP RGB sensor connected to a telephoto lens.
alleviate the effect that all these megapixels would typically have on darker planes. The sensors inside the P20 Pro are huge – easily several times larger than what you see in most smartphones. This makes the pixels themselves larger, which helps to attract much needed light in less than ideal photo operations, but it creates a packaging nightmare in thinner, more compact cameras. 
L & # 39; Sony IMX586 borrows some tricks. the total of 48 megapixels in 12 megapixels with increased sensitivity to light.What is said, the IMX586 is not bigger than a conventional image sensor, which means that he should be able to adapt to more devices.On the day, when things are the ear and the light are not very worrying, the sensor will use all 48 of these megapixels to provide a cleaner shot.
Of course, we will not know exactly how the IMX586 compares to sensors in modern phones for some time. In itself, it probably does not replace a set of sensors and multiple lenses, all serving different tasks with a layer of software that brings everything together. But it is more versatile, and will likely appear in a wider range of flagship offerings because of its small footprint.
Sharper and brighter pictures are not all that the IMX586 can do, either. The latest Sony sensor can also capture 4K video at 90 frames per second, which is currently not possible on any smartphone.
According to Sony, the IMX586 will begin to hit manufacturers in the fall, which means that you will probably see phones launched in mid-2019.
