DIY frame-to-frame telecine machine using Raspberry Pi 3 in operation

Telecine machine to digitize old Super 8 films using the frame-by-frame procedure. The Raspberry Pi 3, which acts as a server for the commands of the main computer, is used to take images and control the movement of the film. Once an image has been captured, it is sent via LAN to the main computer, which post-processes the image and saves it on the hard disk. When the client program receives an image, it requests the following image from the server program. Both the client and server program software have been written in Python 3. A film stepping motor is used to move the film, which advances frame by frame with great precision, without the need to use a detector to take the image. The operation may seem somewhat slow, but it is necessary to take into account that three photos are taken for each frame, in order to obtain HDR images.
