Method and device for scanning a film

摘要

A method and apparatus for scanning a film, in which the film is illuminated by a light source and the light signal coming from the film is fed in channels to a plurality of imaging devices each defining a channel, wherein an exposure for the channels is adjusted to achieve different exposures of the film in at least two of the channels. The signal recorded by the imaging devices is stored as an image having a high dynamic range.

主权项

1. A method for scanning a film comprising:
illuminating the film with a light source to produce a light signal; receiving said light signal at a plurality of imaging devices, each imaging device defining a channel; adjusting an exposure of at least one of said channels to produce different exposures of the film in at least two of said channels; generating, in said plurality of imaging devices, image data indicative of said different exposures of the film; and combining said image data from said plurality of imaging devices and storing said combined image data on a storage medium as a high dynamic range image (HDRI).
