Sony predicts: smartphone camera quality will surpass DSLR cameras in two years
According to Sony If smartphone cameras want to surpass DSLR and mirrorless cameras, they must meet several important factors. The first factor is the size of the sensor. The size of mobile image sensors is expected to reach 1 inch and even beyond in the next two years. It should be noted that previously the smartphone Sony Xperia Pro I was equipped with a 20-megapixel image sensor with a diameter of 1 inch. Of course, due to the limitations of the distance between the lens and the sensor, only 12 megapixels of the surface of this sensor can be used, which practically turns it into a 1/1.3-inch sensor, which is quite common in other flagship smartphones.
Another factor is the new structure of image sensors. For example, the potential of Sony’s new sensor (double-layer CMOS) cannot be ignored. This new sensor separates the manufacturing process of the photodiode and transistor layers and optimizes them more effectively. While in previous designs, both elements (photodiode and transistor) were on the same wafer. According to Sony, in this new structure (compared to conventional sensors that are exposed from the back), each pixel is saturated with light up to twice as much, which increases the dynamic range and reduces noise in low-light environments.
Even if smartphone image sensors can’t get big enough to compete with APS-C cameras, smaller sensors will be able to capture more light in the near future. It’s not clear when this kind of technology will make its way to smartphones, but for now, Sony It uses it in making its advanced mirrorless cameras.
Another effective factor in the growth of smartphone cameras is artificial intelligence. Artificial intelligence processing capabilities in combination with advanced hardware will be effective in improving things like multi-frame HDR, increasing the zoom range and video recording quality. Obviously, computerized photography has made smartphone cameras appear beyond expectations. The $599 Pixel 6 is just one small example of this development. . Currently, the industry trend is towards combining image signal processing with machine learning (both on-chip and on-device). Needless to say, the processing power of smartphones is already more than that of DSLR cameras and it is expected that this power will increase more rapidly.
It is interesting to know, Sony not long ago by unveiling a smartphone Xperia 1 IV, a first in the mobile industry , unveiled a camera with a variable focal length. The lens of this camera is of periscopic type and its focal distance changes between 85 and 125 mm. In this way, you can experience the joy of zooming with DSLR cameras while working with Xperia 1 IV. With this account, if it is possible to expand the range of the focal length, this technology can eliminate some of the problems of camera sets in smartphones – including the use of multiple image sensors, lack of space, high cost, and inconsistency of image and lens quality.
Thus, the day may come when we will no longer see multiple cameras on the back of smartphones. Also, with all the advances in smartphone cameras, maybe in less than two years, you won’t be able to tell if a photo was taken with a professional camera or a smartphone.
