Introducing7 Key Innovations


TDI Sensor

• TDI – Time Delay and Integration - Advantages– High sensitivity– High speed– High flexibility

• Scanning Speeds (35mm 4perf)– 15 fps in 4K resolution– 25 fps in 2K resolution

• About 50 Times More Sensitive– Compared to single line CCD sensor– Lens with small aperture resulting in large focal

depth– Easy to set focus – tolerant to film bending

• Low Power Light Source– LEDs with long life

• Focus Adjustment While Film Is In Stop

Innovation 1


LED Illumination• Low maintenance, low operational cost• Flashed with line scanning frequency• Pulse-width-modulation for light level control • Optical color matching• Various film stocks are illuminated with different

spectral wavelengths (R1, R2, G, B)• Cool, durable, (Nitrate film friendly)• Diffused in an Integration Sphere for reduced visibility

of dust and scratches

Innovation 2


Roller Gate• Precision Roller Gate

– Film is running on the roller for ~ 8 frames ensuring best intra-frame steadiness

– Best for legacy films– Safe – gentle – clean – quiet – Rollers are the only parts touching the film

• Interchangeable 35 and 16mm lens gate assemblies (LGA)

• Maximum aperture 25.80 mm / 1.016 inch– Perforation edges visible on both sides

• Continuous transport via capstan

Roller GateInnovation 3


No pinsNo sprocketsNo skid plate No edgesNo frictionNo abrasionNo harsh audible noise

Roller Gate


35 mm Lens Gate Assembly (16 mm optional)

2 Gate Rollers, just the edges of the film touching the free-wheeling gate rollers

Capstan

Optical Perforation Detection• IR illuminated perforation holes• Perforations are sensed by a dedicated line camera• Widely independent from film shrinkage• Proven algorithms to provide correction vectors• Touch-free Pin Registration

– Image repositioning with a precision of 1/64 of a 4K pixel (~ 0,1 micron) in the spatial processor

• For both 16mm and 35mm film• System redundancies ensure tolerance to damaged

or broken perforations

Optical Perforation DetectionInnovation 4


Dedicated Processing• Sub pixel steadiness processing• LUTs, (log, de-log, lin, 1/x) all in 16 bit• Image scaling, cropping, reformatting• Frame buffer• Proxy generation for cache supported navigation• Scanner calibration • Camera link interface to TDI cameras• PCI-express interface to work station

Dedicated ProcessingInnovation 5


In-built HDR

• DFT has invented a technique* that has been developed to increase, by over 3 stops, dynamic range of a film- scan without affecting either the resolution of the scan or the speed of scanning

*Patent Applied

Dedicated ProcessingInnovation 6 – Coming Soon


Wet Gate System

• DFT is introducing a wet gate system in-built in the scanner

• The system uses an environment friendly process

Dedicated ProcessingInnovation 7 – Coming Soon
