Defect of the soiling, the scar and the dirt etc on the film, in order to adjust the case of digital treatment of the especially film, manner and the device which detect these defects

摘要

As for this invention, defect of the soiling, the scar and the dirt etc on the film, for example, in order to adjust the case of digital treatment of the film, it regards the manner which detects these defects. The manner which relates to this invention the film (1) is allotted on one end side, in order to illuminate at the wavelength which differs two illuminants (3a and 3b) with, is allotted the range where the top of the film is narrow at least on other end side of the film, does two images of the range which illuminates the light beam from two illuminants (4a and 4b) by, by making the film the optical device pass which has with the glass lens which is projected to the linear photosensitive component which corresponds to the wavelength of two illuminants respectively. Furthermore, comparing the digital data which is obtained from two detection components, it detects from the result and it adjusts. This invention, is suited for the use of detection of defect of the soiling, the scar and the dirt etc on the film.
