At the IBC, Cintel is showing a new module called D/SCO for its Ditto film scanners. D/SCO stands for “Dust/Scratch Concealment Option”. This is a technology that filters scratches out of scanned film images by optical means.
The light from red, green and blue light-emitting diodes is directed through a diffusion sphere (an internally diffusely mirrored hemisphere) in such a way that it strikes the film not perpendicularly, but diffusely. The new optics use this diffuse image to reconstruct the colour layers beneath the scratches. In this way, it is possible to remove almost all surface damage that does not cut through the film’s colour layers. If the colour layers themselves are damaged, the damage is reduced but remains present.
Such more severe damage can be corrected in other software using a defect map generated by the scanner. The defect map more or less corresponds to the infrared scan in other scanners; all damaged areas are marked white in it.
Cintel’s D/SCO option is available immediately and costs around 20,000 dollars.
