单词 | unsharp masking |
释义 | unsharp maskingunsharp masking(un-sharp ) A process for amplifying fine detail in the image on a photographic plate. A positive contact copy is made through the glass on low-contrast film. The copy is blurred, containing only the large-scale features of the original image; this is the unsharp mask. When placed in contact with the back of the plate, it effectively cancels out the large-scale features, revealing the fine detail on the plate.unsharp maskingun·sharp mask·ingSee USM |
