Abstract
The invention relates to a method of obtaining a stereoscopic signal from a sequence of monoscopic images. The method firstly comprises a step (S10) of obtaining a sequence of monoscopic images having been captured by an image acquisition apparatus in an acquisition mode enabling several images to be shot in the course of a regular movement substantially tangential to the plane of the lens of the acquisiton apparatus. That step is followed by a step (S31) of forming pairs of images from the sequence of images, each pair being formed on the basis of a predetermined temporal distance then a step of calibrating (S32) the images of the pairs formed, so as to improve the visual correspondence between the two images; Finally, a stereoscopic signal is constructed (S33) from the pairs so calibrated.
