With Sony's new camera sensor it's easy to record super slow motion fighting scenes on phones


Soon you might be able to record super slow motion videos from your smartphone itself, as in at amazingly slow speeds like you see in action movies that, for example, gives some sense to the utterly bewildering fighting scenes.

Sony has developed a new camera sensor for smartphones that can record 1000 frames in a second for Full HD videos. Not to mention it is one of the fastest camera sensors of its type that reduces distortion when shooting fast moving objects.
The 21.2 megapixel CMOS sensor includes a "DRAM" memory chip that can temporarily store all the frames shot at high speed and are sent to the image processing chip -- that resides on the phone chipset -- at a normal rate.
The sensor is capable of reading one still image of 19.3 million pixels in 1/120 of a second which Sony says is approximately four times faster than sensors currently used in the smartphones. So the photos taken of a fast moving object will be free from any distortion as the camera is inherently fast at making them and not just processing them.
Sony revealed in a blog post that "in order to realize the high-speed readout, the circuit used to convert the analog video signal from pixels to a digital signal has been doubled from a 2-tier construction to a 4-tier construction". Which simply means the sensor includes a storage chip, fused between the two sections of the sensor -- one converts light to electrical signals and other readies it for the ISP -- to hoards the frames before they go out for processing.
This is different from a buffer memory used for burst shots where the frames are stored after processing and before they make it to main storage for viewing.
Though we don't know yet if the duration of a super slow motion video recorded on a smartphone carrying the sensor would be limited. But Sony claims it would automatically kick in whenever the sensor detects "sudden subject movement" and begin the high speed shooting if set that way.
The sensor can otherwise record in up to 4K resolution at 60fps and Full HD or 720p resolution at 240fps. Currently iPhone 7 or the Samsung Galaxy S7 can do 240fps at 720p. Sony has also posted a video that shows off how slow will be the new super slow motion sensor, take a look.
