Title
(EN) METHOD AND APPARATUS FOR DETERMINING THE SHOT TYPE OF AN IMAGE
(FR) METHODE ET APPAREIL POUR DETERMINER UN TYPE D'IMAGE PHOTOGRAPHIEE
Abstract
(EN)
A method and apparatus for determining the type of shot of an image is disclosed. The method comprising the steps of: assigning (203, 205) portions of the image to at least a first cluster or a second cluster, the clusters having different ranges of depth values associated therewith; and determining (207, 209) the shot type of the image on the basis of whether both the first and second clusters have been assigned at least one portion or whether there is a stepped or gradual change in the difference between the depth of the first and second clusters.
(FR)
L'invention concerne une méthode et un appareil pour déterminer le type d'une image photographiée. Cette méthode comprend les étapes consistant à: attribuer (203, 205) des parties de l'image à au moins un premier groupe ou à un second groupe, les groupes présentant des plages différentes de valeurs de profondeur associées à ceux-ci; et déterminer (207, 209) le type d'image, à la fois en fonction de l'attribution d'au moins une partie de l'image au première groupe et de l'attribution d'au moins une partie de l'image au seconde groupe, ou en fonction d'un changement échelonné ou graduel de la différence entre la profondeur du premier groupe et du second groupe.
