I did not touch on that subject, as my focus was strictly on the capability of the camera hardware. But since you mentioned it, I'll expound as best I can on what LE can and can not do regarding enhancement.
Various filtering techniques may be applied to both still and moving images. By filtering, I'm including sharpness enhancement, blurring, brightness, contrast, gamma, plus a multitude of techniques that involve overlaying an image over itself and applying additive, multiplicative, subtractive, dodging, burning (plus others) of luminance, color, edge enhancement, interpolation, etc.
Note that no technique may *add* missing information to an image, that 'fills in the blanks', other than for approximation or assumption of 'what should be there based on what surrounds it': this smooths the image rather than enhances clarity but can be useful.
Applying sharpness algorithms is the best technique and most common used to enhance clarity, but this has limits. Increasing sharpness detects pixel transitions and attempts to clarify the edge relative to surrounding pixels.
