Device for stereoscopic pictures with a base-defining system

Abstract

Abstract 1. A stereoscopic viewing device with a variable base comprising means (1 to 4) for viewing as from a first and a second viewing point spaced by a variable distance B termed the base in two directions of view making an angle of THETA termed convergence, said means (1 to 4) comprising : - at least one variable focal length objective (1 and 2) ; - a device (17) for controlling the objective (1 and 2) for controlling the setting of its focal length, the setting of the focus and the setting of its diaphragm ; - a device (7 to 12) for the automatic control of the convergence and the automatic control of the base ; - a device (18) for the operation of the automatic control device (7 to 12) in order to determine a value for the convergence and a value of the base as a function of the setting of the focussing of the objective (1 and 2) ; characterized in that the device (18) for the operation of the automatic control device (7 to 12) determines the value of the convergence and of the base as a function of the setting of the focal length of the objective (1 and 2) as well in accordance with data stored in a memory (15 and 16), the setting for the focus of the objective and the value for the setting of the focal length being provided by the device (17) for the operation of the objective (1 and 2).
