METHOD AND DEVICE FOR TRANSMITTING A VIDEO SEQUENCE COMPRISING A FACE IN A MOBILE VIDEOPHONE SYSTEM

摘要

The device comprises a means for capturing a current image, means MT for treating the image thus captured comprising an ETC coding stage for the captured image comprising an MM image memory storing a previous reconstructed image, a unit for estimating movement BEM connected to the output of the acquisition means in order to create an estimation of movement and a prediction unit BEM in order to create a predicted image from the previous reconstructed image and information on the estimation of movement, in addition to emitting means for the image delivered by the treatment means. The coding stage ETC also comprises a detection unit for the face DVS in said image, which is connected to the capture means and provides an indication of the localization of the area of the face in said image. The output of the detection unit for the face is connected to an input of the movement estimation unit.
