OmniVision: a 4 K sensor compatible smartphone...

Film with its smartphone in 4 K will perhaps become a reality by the beginning of next year, there will more be to equip themselves in compatible TV...


After the Nokia PureView proposing to jolis clichés to 41 million pixels, OmniVision Society announces the launch of a new sensor for smartphones capable of filming in 4K2K... and even more! The reference of this new CMOS sensor is OV16825 and aligns 16 million photosensitive cells or already on a surface of only 1.34 µm each. These already operate technology originally introduced in 2007 by the same company and named "Back-illuminated CMOS" placing the substrate containing the photo-cathodes directly across from light to capture and put behind all the wiring necessary for the functioning of these cells. This technique allows to pass 60% of light being captured to nearly 90%.


The capabilities of this new sensor are rather impressive, since it will be possible to film scenes in Full HD at 60 fps with a system of digital stabilization, but also in 4K2K - or 3840 x 2160 - 60 images per second without stabilization and finally in full definition of the sensor - is 4608 x 3456 - 30 images per second. OmniVision is also on his sheet a new sensor OV16825 has all the essential features for the taking of photo, such as the setting of the exhibition or the sensitivity expressed in ISO. Output, it will be possible to send images to format RAW 10 and 12-bit for a richer colour rendering, 1024 levels of colors for the 10-bit and 4096 colors for the 12-bit levels.

If manufacturers engage in a race to the finesse in the market of smartphones, this sensor will not respond. The size of the sensor is 1/2.3 "instead of" 1/3.2 in normal time and measure 9.2 x 8.9 mm for the single die and 1.28 x 1.18 cm for the complete package. There is still a last problem to be overcome for the manufacturers, the flow of data sent by this sensor must be huge. It seems difficult for the SoC current to be able to support such a definition. Perhaps the next mobile processors will fail, knowing that this type of sensor is not due until early 2013 and will also address the market of compact cameras and camcorders.
