A system and method for producing formatted information related to at
least one image-capture appliance and/or at least one image-restitution
appliance. The system and method provide for production of formatted
information related to defects of the appliance, especially blurring and
noise, from a measured field. This measured field is obtained from a
universal set by performing the operations: capturing or restituting the
universal set by the appliance to produce an image; choosing an image
zone within the image; calculating a reference image from the image;
selecting, within the reference image, a reference zone homologous to the
image zone; choosing a base for representing all or part of the image
zones and reference zones; selecting variable characteristics of the
appliance; and in this way the measured field is obtained. The system and
method are applicable to photographic or video image processing, in
optical devices, industrial controls, robotics, metrology, etc.
