A new method for testing the resolution of digital cameras has been developed. The new method is an extension of the ISO 12233 Slanted-edge Spatial Frequency Response test 1,2 . The new method computes the spatial frequency response along the edge of a circle. It is especially well adapted to inexpensive imaging systems with rotationally symmetric lens distortion. In addition to presenting the new method, a set of practical improvements is described which can be applied to both the slanted-edge and circular-edge methods.
