Phone cameras have features increasingly amazing, and in some cases they surpass professional cameras. For example, you could spend more than a thousand dollars in a camera that records in 1080p at 120 fps, while a modern high range mobile phone has it built-in. obviously, the size of the sensor and the image quality differ from one another, but it still is amazing that today’s mobile phones are able to record at such frame rate with such high resolution.
Cameras able to record in 4K at 60fps and 1080 at 240 fps thank to Sony’s new sensor.
On top of that modern mobile phones can record in 1080 at 120fps, or 4K at 30 fps, the new sensors designed by Sony entail that in some time no so long from now we will see the first mobile phones able to record in 4K at 60fps, 1080p at 240fps, slow-motion with an amazing quality and able to play at that frame rate in compatible monitors (since there are already some with a spec up to 240 Hertz), with a maximum theoretical frame rate of 1.000fps in 1080. Regarding photographs, the sensor will count with 21.2 Megapixels.
Sony has designed this new phone CMOS sensor that consist in three layers, including in one of them something that has not been previously seen in a camera sensor: a RAM memory chip. Specifically, it will include a 125 MB chip that can read 19.3 million pixels in 1/120 seconds, which is four times faster than current chips.
Current phone sensors have a hard time taking pictures at high speed, these, having slight distortion due to the capture rate and the way that sensors work, even in speeds greater than 1/300 seconds. The new Sony sensor is four times faster than current ones, which helps to highly mend the problem. The pixel size of the sensor is 1.22μm, which improves the lighting as well in low light spaces, while reducing noise.
Higher speed thanks to the RAM and its new construction.
Digital sensor shutters on mobile phones don’t count with a mechanical shutter as it happens in Digital single-lens reflex cameras, for which exposure time is control digitally. That’s why distortion is created when taking pictures of moving objects as car or a train. The inclusion of the RAM chip in the sensor allows higher processing speed, while reducing software loading time.
Sony has not announce when the new sensor with RAM will be available, but it should be for year’s end or earlier next year, and it probably will be release in Xperia phones, coming later for other brands.
