Descrizione del progetto
Uno scanner innovativo per digitalizzare i film storici
I progressi della tecnologia digitale hanno contribuito a preservare il nostro patrimonio culturale; tuttavia, c’è ancora molto da fare. Vaste raccolte di film storici devono ancora essere digitalizzate. Nonostante la crescita economica dell’8 % all’anno e oltre 400 milioni di euro di valore stimato, la digitalizzazione deve affrontare alcune sfide. In primo luogo, sul mercato mancano scanner professionali aggiornati per pellicole e si percepisce una lacuna di conoscenza sui film storici tra i fornitori di servizi. Il progetto VeCoScan, finanziato dall’UE, svilupperà e collauderà un’unità di scansione multispettrale e versatile progettata per adattarsi al tipo di pellicola specifico da scansionare e in grado di digitalizzare correttamente l’intera gamma di colori delle pellicole. Il progetto offrirà prove delle proprietà fisiche degli stock di pellicole e modelli per la ricostruzione del colore secondo standard scientifici.
Obiettivo
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.
