ABSTRACT:
A device for measuring density of photographic transparencies, such as recorded photographic film, which is generally used in a color scanner system in which a photographic film carrying a colored image is scanned in X and Y directions with a light beam, so-called "flying spot", and the transmitted beam is separated into a plurality of component color beams which are then converted into electric signals indicative of densities of the respective component colors, which are then adequately adjusted in magnitude and utilized for preparation of multi-color printing blocks, the device having means for correcting density errors relating to polarization characteristics of the material of the film.
