I have a coolplx Nikon camera how do you change to make it not blurr? To make it clear?

Clear pictures?
How to make photo bigger and smaller when you take a picture?

READ THE MANUAL

Bigger?

Set your camera to its highest resolution…

Smaller?

Do that in post and rename the smaller file so you do NOT overwrite your original

Reduce blur?

Shoot at thigh shutter speeds, exotically when you are using the camera at its longest zoom focal length.

You do know how to use the camera optical zoom, right?

All of this is in your user manual.

Scroll and browse until you see the button options or something
