Piezoelectric stepper to improve image resolution in digital cameras

Digital cameras are already pretty high resolution, but in good light, given the high sensitivity of the sensors, it would be possible to multiply the effective sensor resolution without changing the chip.camera enhancement

I had this idea a decade ago or so, but only just got around to drawing a nice pic. The CMOS sensor could obviously be swapped to any other imaging tech.

As a free afterthought, another piezo crystal on the back could also step the sensor forwards and backwards to make sure at least one image is in crystal-clear focus.
