Normally we adjust the parameters to make image looks better, however some improper parameters will cause the blurred. Sharpness and DNR level will affect the image definition.
Sharpness mainly works on object edge. If it is too low, the definition of object edge will be blurry (the left); otherwise (the right) it will be too sharp.
DNR level will also affect image definition. Image noise will be reduced when DNR is enabled, if DNR level is too high the image details will lose.
