For example, an M4 Carbine with a twist rate of 1 in 7 inches (177.8 mm) and a muzzle velocity of 3,050 feet per second (930 m/s) will give the bullet a spin of 930 m/s / 0.1778 m = 5.2 kHz (314,000 rpm).
314 krpm, oh. No way to correct for that digitally.
It would not be impossible correct. (I've worked in digital image processing.) There would be many difficulties such as surviving both firing and impact to transmit, which might be possible with a hard metal bullet and a soft target. Still miniaturizing everything and making a sufficiently fast tiny camera would be hard. It is also not hard to calculate the trajectory if you know the end points and barrel angle.
I'd think that the biggest issue would be exposure time. It seems that you'd need a very high frame rate to avoid massive blur. Or maybe you mean some sophisticated DSP that converts what looks like successive frames of lots of concentric circles of color into sharp pictures.

Why would that be a problem?
