Abstract
The resolution of a digital camera is defined as its ability to reproduce fine detail in an image. To test this ability methods like the Slanted Edge SFR measurement developed by Burns and Williams1 and standardized in ISO 122332 are used. Since this method is - in terms of resolution measurements - only applicable to unsharpened and uncompressed data an additional method described in this paper had to be developed. This method is based on a Sinusoidal Siemens Star which is evaluated on a radius by radius or frequency by frequency basis. For the evaluation a freely available runtime program developed in MATLAB is used which creates the MTF of a camera system as the contrast over the frequency.
