Noise can't be "blurred". It's not affected by the optical resolution.

Think about where the noise comes from, then have another go.

I already did. The noise can't be blurred.

Try again

No reason. As one would hope you'd know, noise is defined by being perfectly random.

Wrong way round, Anders. Noise is modelled as a Poisson process. The actual noise depends on the random arrival of photons and that in turn depends on the distribution of the photons.
