I suspect that, with respect, you don't understand the issue. Definition is nothing to do with interpolation interpolation, and the sheer physics of having a small sense and a small sensor, trying to detect small things from a distance with a device that is designed to output impressive looking images rather that true capture, compared to a big lens, big/full frame sensor and a shorter distance with an SLR camera.
The effect is small lenses and small sensors have lots of 'photoshop' type of corrections going on to produce impressive images with cost effective architecture.
Feel free to go ahead and stick with your rainwashing theory, I'm going the game.
