On Semiconductor has launched two new 4k ready CMOS global shutter sensors with new technology for reduced noise and improved image quality. The parts are geared to surveillance, automotive, consumer devices and industrial applications. Both sensors are able to do high frame rates at 4k at full resolution.
The XGS 8000 is an 8.8 Mp (4096 x 2160) 4k / UHD resolution Global Shutter CMOS image sensor in 1/1.1 inch optical format capable of 120fps at full 8.8MP resolution. This first one geared for smaller devices. The XGS 12000 is a 12.6 Mp (4096 x 3072) CMOS image sensor in 1″ inch format, supporting up to 90 fps readout at full 12.6MP resolution. This sensor is better for higher resolution solutions.
Sony Semiconductor division has announced the new IMX183CLK-J “Mono” & IMX183CQJ-J “Color” Sensors in 1″ size. The sensor seems to be a step up compared to the ones used in the last RX100 and RX10 camera series. While there is no mention in the press release of a stacked combo; the sensor itself should be able to be built on a high speed stacked memory package which should allow extreme frame rates at HD resolutions.
The sensor used in the RX100 V, for example, is a 1″ Exmor RS which allows for HDR capture in both photo and video modes. The new sensors announced are of the R variety “No video HDR” which could mean another variation of the sensor will debut with the RX100 VI. Considering the cameras are due for a refresh this year we expect Sony to up the ante when it comes to read-out data speeds and use their stacking technology.
Regardless of what the GoPro and Ambarella marriage can provide in tandem hardware it is clear the company wants to branch out of the fledgling sales of GoPro which have tanked in recent quarters and the stock price from a high near a $100 USD is now trading at a mere $12 which is half the IPO price. By branching out it seems they want their chips in many more imaging devices and be less affected by the GoPro product cycle.
The announced H2 and H12 chips are able to provide beefy 4k specs at high frame rates for mobile devices at a mere 2 Watts of power. As to 1080p frame rates it will remain to be seen how this powerful new chip can handle that in a camera design and how it is implemented to squeeze that performance. 120fps at 4k from the H2 in theory should be able to yield 480fps at 1080p just counting the Pixel processing. This however can be limited by the rest of the components like imaging sensor.
