Abstract
(EN)
The present disclosure relates to an image processing device and method, which are capable of suppressing an increase in prediction error. Image data is encoded by a method corresponding to the type of a pixel. For example, image data is encoded by a method according to whether the pixel is an image plane phase difference detection pixel or a normal pixel. Further, the encoded data of the image data is decoded by a method corresponding to the type of the pixel. For example, the encoded data is decoded by a method according to whether the pixel is an image plane phase difference detection pixel or a normal pixel. The present disclosure can be applied to, for example, an image processing device, an image encoding device, an image decoding device, an imaging element, or an imaging device.

La présente invention concerne un dispositif et un procédé de traitement d'image qui sont aptes à supprimer une augmentation d'erreur de prédiction. Des données d'image sont codées par un procédé correspondant au type d'un pixel. Par exemple, des données d'image sont codées par un procédé selon que le pixel est un pixel de détection de différence de phase de plan d'image ou un pixel normal. En outre, les données codées des données d'image sont décodées par un procédé correspondant au type du pixel. Par exemple, les données codées sont décodées par un procédé selon que le pixel est un pixel de détection de différence de phase de plan d'image ou un pixel normal. La présente invention peut être appliquée, par exemple, à un dispositif de traitement d'image, un dispositif de codage d'image, un dispositif de décodage d'image, un élément d'imagerie ou un dispositif d'imagerie.
