Software for measuring the spatial frequency response (SFR) of cameras SFR-Fit is camera resolution measurement software that measures MTF (Modulation Transfer Function). MTF indicates spatial frequency characteristics using multiple distortion and uniformity-corrected sine patterns that can be presented across one or more displays. Conventional MTF measurement methods can have issues with black box camera systems that prevent the acquisition of the RAW or minimally processed image. If these systems have sharpening enabled, slanted edges can overstate MTF, especially at high frequencies. The SFR-Fit measurement system can produce highly accurate measurements of automotive cameras and is compatible with ultra-wide-angle lenses.
