(54) Title (EN): SHARED BLOCK COMPARISON ARCHITECTURE FOR IMAGE REGISTRATION AND VIDEO
CODING
(54) Title (FR): ARCHITECTURE DE COMPARAISON DE BLOC PARTAGÉE POUR UNE MISE EN
CORRESPONDANCE D'IMAGE ET UN CODAGE VIDÉO
(57) Abstract:
(EN): This disclosure describes an efficient architecture for an imaging device that supports image registration for still images and
video coding of a video sequence. For image registration, the described architecture uses block-based comparisons of image blocks
of a captured image relative to blocks of another reference image to support image registration on a block by block basis. For video
coding, the described architecture uses block-based comparisons, e.g., to support for motion estimation and motion compensation.
According to this disclosure, a common block comparison engine is used on a shared basis for both block based image registration
and block-based video coding. In this way, a hardware unit designed for block based comparisons may be implemented so as to
work in both the image registration process for still images and the video coding process for coding a video sequence.
(FR): L'invention concerne une architecture efficace pour un dispositif d'imagerie qui prend en charge une mise en
correspondance pour des images fixes et un codage vidéo d'une séquence vidéo. Pour une mise en correspondance d'image,
l'architecture décrite utilise des comparaisons sur la base de blocs de blocs d'image d'une image capturée par rapport à des blocs
d'une autre image de référence pour prendre en charge une mise en correspondance d'image bloc par bloc. Pour un codage
vidéo, l'architecture décrite utilise des comparaisons sur la base de blocs pour prendre en charge, par exemple une estimation
de mouvement et une compensation de mouvement. Selon la présente invention, un moteur de comparaison de bloc commun
est utilisé de manière partagée pour une mise en correspondance d'image sur la base de blocs et un codage vidéo sur la base de
blocs. De cette manière, une unité de matériel conçue pour des comparaisons sur la base de blocs peut être mise en œuvre afin de
fonctionner dans le processus de mise en correspondance d'image pour des images fixes et le processus de codage vidéo pour coder
une séquence vidéo.
