V2 Sony imx219 specifications?

Wed Aug 21, 2019 10:24 pm

The V1 OV5647 Pi camera has published specifications for S/N Ratio, Well Capacity, Dynamic range and sensitivity.
But the V2 Sony camera does not list them. https://www.raspberrypi.org/documentati ... re/camera/

Are they available someplace else? Mainly interested in the S/N Ratio of the IMX219 imager.

Thanks for the link - I reviewed and still don't find these values in the datasheet.
They state the IMX219 has high sensitivity, low dark current, but don't give values. One plot of color sensitivity (RGB) but again no values.
No mention of Well capacity nor dynamic range.

I would think S/N Ratio, Well Capacity, Dynamic range and sensitivity would be a common thing to specify for a camera imager, but maybe not.

All information we have from Sony on the IMX219 is under NDA.
The datasheet HermanSW linked to has been released by someone else, probably breaking their own NDA with Sony.

Sorry, if the information hasn't been published, then we are not at liberty to disclose it (and indeed may not have those specific numbers to hand).

Is there an imager chip in the same product family as the Sony imx219 that would publish these specs?

Maybe these specs are worse than the v1 imager (OV5647) - that is why Sony won't publish them?

Where did you find those values?
The ov5647 spec on sparkfun says "S/N ratio tbd":

Found the SNR (36dB) here: https://www.raspberrypi.org/documentati ... re/camera/
But no documented reference was given. Your link is a preliminary spec for the OV5647.

Maybe a final released OV5647 datasheet was disclosed (under NDA) by Omnivision to Pi Foundation?
Or was determined via measurements?
