Digital static camera
A patented design
The patented concept implements an algorithm of simulation of a linear scan starting from a radial scan of the image, which has the advantage of being able to be carried out at high speed by one or more linear sensors.
Radial scan is carried out in the image plan of the objective of the camera, either by sensors placed on a rotating support, or by the rotation of the image by means of a prism, the sensors being fixed with respect to the frame.
The scanning movement being a continuous rotational movement and not an alternative linear movement, the speed of digitalization is limited by the performances of the sensors rather than by mechanical constraints.
A new concept to scan books and bound documents.
Slowness of digital static cameras has been until now an obstacle for their use for systematic digitalization of books or other bound documents (Patents, reviews, registers…).
Used with a support for automatic digitalization, and coupled to a laser printer or a digital copier, this new camera makes it possible to implement the ideal station for copying book pages for libraries.
