Abstract
Digital reproductions of any size made from images scanned from film or taken by an electronic camera are optimally sharpened in a system-wide operation. The images are captured by an imaging device having an electronic imager and subsequently reproduced in a reproduction device, both imaging and reproduction devices having respective modulation transfer functions. Initially, the imaging device modulation transfer function and the reproduction device modulation transfer function are stored in separate devices. After an image is captured with the imaging device, a system modulation transfer function is generated from the imaging device modulation transfer function and the reproduction device modulation transfer function. Then a sharpening function is generated from the system modulation transfer function and the sharpening filter function is applied to the image captured by the imaging device in order to sharpen the image.
