Automated minimum resolvable contrast (AMRC) test |
摘要 |
A system for automatically performing the Minimum Resolvable Contrast (MRC) test on an image sensor, such as a TV camera, using a digital signal processor for controlling the testing, wherein an edge response from a square aperture target edge is used to generate a Modulation Transfer Function (MTF) which, in combination with signal and noise data obtained using the square aperture target, provides an input to automated MRC (AMRC) processing equations, from which a value can be calculated for an AMRC output. Alternatively, a slit target may be substituted for the square target aperture when measuring camera MTF.
