摘要:
This International Standard specifies the principal MTFs associated with a sampled imaging system, togetherwith related terms, and outlines a number of suitable techniques for measuring these MTFs. It also defines ameasure for the “aliasing” related to imaging with such *** International Standard is particularly relevant to electronic imaging devices such as digital still and videocameras and the detector arrays they *** a number of MTF measurement techniques are described, the intention is not to exclude othertechniques, provided they measure the correct parameter and satisfy the general definitions and guidelines forMTF measurement as set out in ISO 9334 and ISO 9335. The use of a measurement of the edge spreadfunction, rather than the line spread function (LSF), is noted in particular as an alternative starting point fordetermining the OTF/MTF of an imaging system.
