This paper describes a motion estimation algorithm and its implementation in Television pictures (temporal conversion, de-interlace technique, prediction, reconstruction, coding).The inter -image processing techniques that we have developed are based on a motion estimation algorithm which determines a motion vector at each pixel that is to be interpolated. The motion estimation algorithm is a differential, iterative, pelrecursive method (Walker /Rao algorithm). Motion field is improved by a multi-predictive procedure with a prediction along motion axis.

Included in an EuropeanProject about stereoscopic Imaging, a 3D pick-up equipment will be developed. This equipment represents an advance tool inasmuch as the goal is to built an automatic and motorised camera. The motorisation ofthis equipment allows precise and remote controls. This is required to provide the large and symetric adjustments for optics and the system. This means we modify the values of the optical and mechanical parameters (focal length, interaxial, angle of convergence) to provide optimal stereo pictures. Two kinds offunctionning are planned. The first kind corresponds to preprogrammed values which regulate all parameters for an expected stereoscopic quality. The second kind allows the cameraman to be free in order to introduce special effects or test special condition to obtain psychophysical results. The image quality will correspond to the CCIR 601 standard for both channels.
