Fascinating! Though, I doubt that the jumping spider's view would have such a blowing DOF, as in the picture. I guess, all vision systems (sensors and processing) would be optimized for primary needs, should these be food search, mating, shelter, and predator evasion? As for dogs, I wonder if for them the "vision" is more than just optical pathway. It may be augmented with olfactory detail to "color" the visuals as needed for their priority. After all, colors is very notional concept, even to humans it's more than just wavelengths.
