Samsung has just announced a new mobile image sensor that may just reveal what's in store for the rumored Galaxy S9 smartphone—specifically in the slow-motion capture department.

Announced earlier today, Samsung's new ISOCELL Fast imager chips feature a 3-stack Fast Readout design that Samsung claims will shoot Full HD 1080p video at a whopping 480fps. That's not quite as fast as the eye-watering 960fps in Sony's high-end Xperia models, but the Sony mode can only capture for a fracture of a second—Samsung's super-slow-motion could potentially offer longer capture times.

According to Samsung's product page, the ISOCELL fast sensors also come with advanced autofocus technologies—such as Dual-Pixel or Super-PD—built into the chip, allowing for very fast focusing in all light conditions. ISOCELL Fast sensors with the aforementioned technologies are currently available with 12 and 16MP resolutions and sizes ranging from 1/2.8" to 1/2.56".

As usual, there is no way of knowing for certain if either of these sensor variants will make it into the Galaxy S9, but it's safe to assume we'll see the new 480fps Full HD mode in a Samsung mobile device in the near future.
