So before we learn how to convert resolution from low to high, we must understand the different kinds of blur.

To know how to fix the blur, you must know what kind of blur you are dealing with. There are 3 main and common types that you should know.

Motion Blur
This occurs when the camera's optical stabilizer does not stabilize a rapidly moving picture. Part of the image appears streaked because of this.
Apps that use automatic shake pattern analysis technology can easily fix this.

Defocused Blur
These pictures are harder to fix as the entire image and its primary subject are blurry. Some programs are able to at least make the image readable but the quality might still be poor depending on how unfocused it is.

Gaussian Blur
These blurs are caused by using a software program to blur every pixel of the image to a set pixel value. An example would be the one that I used for the game earlier, I intentionally blurred the picture using a Gaussian Blur. These blurs are actually easier to reverse than defocused images.
