Abstract | The present invention appropriately controls the focus. An imaging device is equipped with a control unit. The control unit sets a first mode or a second mode on the basis of predetermined conditions. The first mode carries out an auto-focus process by moving a focus lens on the basis of the contrast in an image generated by means of an imaging unit. The second mode carries out an auto-focus process by moving the focus lens on the basis of a matching processing result pertaining to a first image and a second image generated by means of the imaging unit while the focus lens was at a different position.
La présente invention vise à commander de façon appropriée le foyer. Un dispositif d'imagerie est équipé d'une unité de commande. L'unité de commande règle un premier mode ou un second mode sur la base de conditions prédéterminées. Le premier mode réalise un processus d'autofocalisation par déplacement d'une lentille à foyer sur la base du contraste dans une image générée au moyen d'une unité d'imagerie. Le second mode réalise un processus d'autofocalisation par déplacement de la lentille à foyer sur la base d'un résultat de traitement de correspondance concernant une première image et une seconde image générées au moyen de l'unité d'imagerie alors que la lentille à foyer était à une position différente. |
