This is a fascinating, retro novelty. Two screws on the opposite side hold the housing over the circuit board and CCD array inside. A frame flip book cut and bound from photo paper prints on a color inkjet printer. Each of the two claw teeth is a symmetric tapered rectangle, with a 0. The listing you’re looking for has ended. The first layer is a narrower strip stuck on the glass with double-stick tape, carefully aligned with the scanner axis.

Microtek ScanMaker 3750i Flatbed Scanner

The same could not be said of the film in the sprocket portion of the path, where the film is free to move about on the sprocket teeth. Squinting stops down the lens aperture of your eye, reducing your visual resolution, thus smoothing the pixel transitions, much like anti-aliasing algorithms in digital photo editors. By comparing to the microphotograph, it is apparent that this film scanner is doing a thorough job of capturing the film image in all its detail.

Correlating the microgek ideal sprocket pattern against the pixel column yields a minimum at the desired Y offset. Maintaining updated Microtek ScanMaker i software prevents crashes and maximizes hardware and system performance.

A film stepper could register each frame under the microscope using a similar technique to what I propose for the flatbed scanning. The loose side-to-side fit of the teeth accommodates the tolerances in the sprocket hole sizes and relative position on the film stock.

Good contrast and sharp definition allows accurate pattern recognition of sprocket hole registration. Best Selling in Scanners See all. Each of the two claw teeth is a symmetric tapered rectangle, with a 0. The Microtek i scanner set up for 16mm film scanning. I presume 33750i motion of the claw is articulated by some combination of a cam and cam follower running off the projector motor.


Note the that dust fiber on the upper right edge resolves to 1 or 2 pixels across; this approaches the Nyquist limit, proving that the digital samples genuinely resolve at that spatial frequency.

Note how the analog grain renders shading, such as the mucrotek of the lady’s cheek or the fontanel on the baby’s head. Microtek ScanMaker i Drivers: It looks much better if you apply an optical low-pass spatial filter, which micotek to say, squint at it! Dust artifacts on the image are mostly not on the film but on a clear carrier I was forced to improvise to trick the film scanner into 7350i the 16mm film was 35mm.

But this loose fit does not imply backlash sloppy registration of the stop-motion in the direction of film travel.

A frame flip book cut and bound from photo paper prints on a color inkjet printer. Solvusoft’s close relationship with Microsoft as a Gold Certified Partner enables us to provide best-in-class software solutions that are optimized for performance on Windows operating systems.

Document lid is removed. There are two layers of transparency material making up the the gate. Note that the sprocket wheels are relieved with concavity towards the center, to likewise avoid contact with the film’s image area. This chip die shown is about 0. My motive for this project centers on my desire to preserve and view a short clip of year-old 16mm movie film, which happens to be the only movie of me taken during my childhood.

The Microtek i includes a flexible ability to scan transparencies, plain paper, and slides in color mode enabling you to scan in sharp clarity and keep the digital records in electronic storage.

Dust appears dark because this is a transmission scan. The sprocket portion of the wheel appears to be a separately machined disk not unlike a star wheel from a clockwork stacked on an axle bearing with a machined center portion. The optimal shape is generated by the involution of the perforation edge as the tooth drops away. The high spatial frequency of the pixel transitions are a form of periodic noise which make this image look worse than it should. With the flexible functionality found on this flatbed scanner, you can meet your document scanning needs every time.

Note that this piece of film has torn sprocket holes from clumsy projection many years ago.
