Title:
LATENT IMAGE BURN-IN DEVICE
Document Type and Number:
WIPO Patent Application WO/2004/077150
Kind Code:
A1
Abstract:
A latent image burn-in device eliminates a burn-in failure with a low-cost detection means, so that a latent image of characteristics data is burned in stably and accurately in an edge portion of a film. The device comprises detection means for measuring the movement amount of a long unexposed film being fed, exposure means provided with a light emitting body having a large number of light projection sources for radiating light such that pixels are formed in a direction perpendicular to the movement direction of the film, and a control device for selecting a large number of light projection sources according to output information from the detection means and allowing them to radiate light so that the exposure means burns characteristics values such as letters and figures in the film. The device is characterized in that digitized latent image data of the characteristics values and inspection data corresponding to the digitized latent image data are integrated in a memory in order to conduct burn-in control.
