Minimum Resolvable Contrast

From Wikipedia, the free encyclopedia

Minimum Resolvable Contrast is a subjective measure of a visible sensor’s sensitivity and ability to resolve data. A series of four bar targets of selected spatial frequencies and different contrast coatings are presented to the sensor. A trained observer selects the smallest target reasonable at each contrast level. The software collects the data and provide a graph of contrast v.s. special frequency at tech luminance level.
