Chinese company Gpixel announces the GCINE3243, its second sensor in the GCINE product series explicitly designed for video, cinematography as well as scenic drone use. ;){kind=tracking} Gpixel GCINE3243: 8K-S35 CMOS sensor
The maximum bit depth is said to be 14 bits per pixel, which requires a correspondingly fast data interface. The GCINE3243 can be connected via 32 sub-LVDS channels, which can transmit 1.05 Gbit/s per channel. With the wafer stacking technology used, the GCINE3243 sensor sounds quite SOTA (State-Of-The-Art). Like other current cine sensors, only the sensors themselves sit on a wafer layer, while the light-facing side houses, among other things, the converters some SRAM, as well as the rest of the logic elements. ;){kind=tracking} Gpixel GCINE3243: 8K-S35 CMOS sensor In addition, the sensor should be able to handle a "dual gain read out", which is currently only found in special cine sensors from Arri, Canon or Blackmagic. Without special "calculation tricks", 81dB signal-to-noise ratio should be possible in 8K - i.e. 13.5 f-stops. In "binned 4K" even 14 f-stops are supposed to be captured, which already completely corresponds to the theoretical possible 14 bits of the data lines, if the converters work linearly. The linear mention could be important, because in a "digital multi-slope HDR mode with deterministic knee points", "relinearization without calibration" with more than 100 dB dynamic range should be possible. This would then correspond to almost 17 f-stops - which currently only ARRI can deliver in practice with its ALEXA 35. Prototypes and evaluation boards should be available immediately for interested developers.  more infos at bei www.gpixel.comdeutsche Version dieser Seite: Gpixel GCINE3243: 8K-S35 CMOS-Sensor vorgestellt mit 60 fps und 14 Bit |
