Paper Abstract

The paper deals with parameters of image sensors, which are important for the image quality evaluation. The influence of the most important parameters upon image quality is investigated. Particularly the modulation transfer function, contrast, dynamic range, the influence of aliasing upon image distortion, sensor resolution, signal to noise ratio and detective quantum efficiency have been briefly reviewed. The most important parameter MTF was described in detail. The main goal was to find the suitable method for obtaining on 2D qualitative parameter - 2D MTF depending on sampling distance, sampling aperture and fill factor. At the end of this paper the influence of the 2D MTF from the point of image quality is evaluated via Matlab CCDSIM for the large area image sensors, used for medical application.
