Panasonic confirms it is nonetheless growing its 8K natural CMOS sensor with WDR and 60 fps world shutter recording: Digital Pictures Overview


One of many first photographs shared by Panasonic revealing what’s, no less than to our information, nonetheless a prototype model of an 8K cinema digicam that may use this natural sensor know-how.

Again in February 2018, Panasonic introduced it was growing an natural 8K picture sensor that supplied huge dynamic vary (WDR) and a worldwide shutter at as much as 60 frames per second (fps). Whereas little has been revealed about that sensor since then, it seems as if the know-how remains to be in growth, as Panasonic has revealed further details about the 35MP Tremendous 35mm sensor.

Evaluating typical BSI CMOS picture sensor design (left), Panasonic’s new OPF/CMOS picture sensor (proper). Be aware how skinny the OPF layer is in comparison with a conventional silicon photodiode. This enables a big space to be dedicated to circuitry, and likewise means every pixel can settle for a wider cone of incident gentle. This will increase the CRA (chief ray angle) from the standard 30-40º to 60º.

As we defined in our preliminary protection of the sensor, this 8K sensor ‘combines an natural photosensitive movie that sits atop CMOS circuitry.’ This design separates the sunshine capturing factor from the readout factor, which means you do not get the compromises and trade-offs that all-silicon CMOS designs carry.

Separating the sunshine seize course of from the sensor’s readout means that you would be able to cease the sensor being gentle delicate, then take the time to learn your complete sensor. In typical CMOS the publicity is ended by beginning the readout course of, so you’ll be able to solely shut your shutter on the charge that you would be able to read-out all of the traces of pixels.

Likewise, making a cost storage space separate from the sunshine delicate a part of the pixel permits larger cost storage capability and therefore wider dynamic vary seize.

Lastly, having a thinner light-sensitive factor that is nearer to the floor of the sensor permits gentle seize from a wider vary of angles, lowering how a lot work the microlenses should do to maximise gentle seize.

In accordance with this newest report from Monoist, which showcases new photographs of the prototype 8K cinema digicam Panasonic first confirmed off again in October 2018 and has as soon as once more highlighted on the 4K/8K Expertise Expo 2021 in Majuhari Messe, Chiba, Japan, this 8192 x 4320 pixel sensor will supply as much as 4 occasions the dynamic vary of a conventional CMOS sensor.

The sensor seems to stem from what was initially billed as a collaboration between Fujifilm and Panasonic again in June of 2013. Fujifilm was mentioned to be engaged on the photosensitive natural movie however has not been talked about in current updates, suggesting the event of the movie know-how has been accomplished and Panasonic is continuous to work on turning the know-how right into a completed product by itself.

Panasonic exhibits off the unbelievable dynamic vary of this new natural sensor.

The demonstration of working samples at commerce exhibits recommend the know-how is sort of prepared for primetime. We do not but know what the sensor’s energy consumption will probably be like, nor whether or not it’s going to be sensible to incorporate it in a client stills/video digicam, so it’s going to be attention-grabbing to see whether or not it may possibly compete with the efficiency and appreciable worth of the stacked CMOS chips that are actually being seen in digicam producer’s high-end fashions.
