Description du projet
Un scanner innovant pour numériser les films historiques
Les progrès des technologies numériques ont permis de préserver notre patrimoine culturel, mais il reste encore beaucoup à faire. De très nombreuses séries de films historiques doivent encore être numérisées. Malgré une croissance économique de 8 % par an et une valeur estimée à plus de 400 millions d’euros, la numérisation fait face à un certain nombre d’écueils. Tout d’abord, le marché ne dispose pas de suffisamment de scanners de films professionnels haut de gamme et les fournisseurs de services manquent de compétences en matière de films historiques. Le projet VeCoScan, financé par l’UE, développera et testera une unité de numérisation multispectrale et polyvalente, conçue pour s’adapter au type de film spécifique à numériser et capable de numériser correctement toute la gamme de couleurs des films. Le projet apportera des indications sur les propriétés physiques des stocks de films et des modèles pour une reconstruction des couleurs basée sur des normes scientifiques.
Objectif
Film archives contain large and diverse collections of historical films. In order to exhibit and exploit these collections
commercially, archives need to digitize their holdings. With more than 400 Mio. € per year globally and growth rates of 8 %
annually, the digitization of analog film material is an exponentially growing market.
However, as a study by the research team has shown, there is no professional high-end film scanner on the market that is
able to digitize the whole range of these films.
The PoC VeCoScan tackles this lack of technical solutions by developing and testing a multi-spectral and versatile core film
scanner unit. This versatile design will allow the film scanner to adapt the spectral distribution and the directional
arrangement of its illumination system, based on colorimetric measurements of film stocks executed by the research team.
The higher image quality of the raw scans will achieve better results in terms of both the accuracy with the original colors
and the potential to digitally reconstruct faded colors that concern an estimated 90% of chromogenic film stocks up to 1980.
The most important bottleneck in digitization workflows is the optical set-up of the scanners. The second bottleneck is a
lack of knowledge of historical films on the part of most service providers. The PoC will address both of these current
drawbacks: by improving the scanner, and by delivering a comprehensive package that includes information about the film
stocks’ physical properties and models for color reconstruction, in line with high scientific standards. As a result, scanning
and post-processing times will be greatly reduced and workflows will become much more cost-efficient. Furthermore, an
accurate digital rendition of analog films is crucial for the long-term sustainability of digital representation.
