What is the difference between image restoration and image reconstruction?
The introduction of this paper explains the difference and gives an example. In short:


  Image restoration techniques presume that data are acquired in the image space; that is, the raw data represent a corrupted version of the image scene. In contrast, images are not directly observed in reconstruction problems. Instead, projections of an image are obtained from two or more angles, and the image scene is pieced together from these projections.
