Abstract
A 3D camera comprises first and second laterally displaced optical imaging systems each comprising one or more lenses. The optical imaging systems also each comprise one or more actuators arranged to move one or more lenses of the respective optical imaging system, and a digital image analyzer configured to evaluate the respective field of view of first and second images of a stereoscopic image pair obtained respectively from the first and second optical imaging systems and to generate a disparity value based on a disparity between the respective fields of view. The 3D camera is arranged in operation to adjust the field of view of one or more images generated by the first and second optical imaging systems responsive to the disparity value so as to reduce the disparity between the respective fields of view of stereoscopic image pairs obtained from the first and second optical imaging systems.
