Just a bizarre thought

[DrPizza]

This just popped into my head: would it be possible to develop software such that:

A. you take a photo of a really complicated intricate pattern
B. the software takes the RAW data & creates its own algorithm to sharpen the image, since it knows exactly what the real image is supposed to look like. i.e. it figures out where any lens flaws are & calculates how to correct for these.
C. It's able to repeat that "fix" for other photos taken with the same camera.

I know it wouldn't be a perfect solution that would turn a 100 dollar lens into a 500 dollar lens, but couldn't some sort of adaptive software be used to at least slightly improve image quality from cheaper lenses?

Sharpening wouldn't really work, since that's a function of the sensor, anti-aliasing, and interpolation.

But I think the PTLens plugin for Photoshop and Lightroom can correct for known lens imperfections. I don't own or use it, however, so don't take my word for it.

Bibble Pro does that.

Some cameras already do that with long exposure shots. They take a picture (of the same length exposure) with the shutter closed, note the incorrectly active pixels, take the regular shot, then subtract out the bad pixels.

Erm, that's dark-frame hot-pixel subtraction. I think the OP is about correcting lens flaws, such as chromatic aberrations (D3/D300/D700 applies to in-camera JPEG and Capture NX2), spherical aberrations, axial aberrations, corner light falloff, distortion, softness, softness, and flat contrast.

Canon's Digital Photo Professional already supports correction for Vignetting, distortion and CA when used with certain lenses.

DxO Optics Pro also does lens correction for a huge collection of lenses
