ABSTRACT
The term performance is used to cover all aspects of an imaging system on its ability to perform a specific task. We talk about optical performance to refer to the efficacy or achievement with which the optical system produces good images. The term image quality is used in a more restrictive sense to describe the fineness
of detail that can be resolved in the image or the similarity between the image and their corresponding object. On the other hand, visual performance is defined by the speed and accuracy of processing visual information (CIE 2011), that is, by how well a visual task, for example, spatial vision, can be performed by a subject.
