Claim 6:
7. A notification apparatus comprising at least one processor and/or at least one circuit which functions as:
an obtainment unit configured to obtain a plurality of object classes organized hierarchically according to a hierarchical structure in which an object class in a higher hierarchy level contains an object class in a lower hierarchy level, the plurality of object classes having been detected from a specific image regardless of a display magnification rate of the specific image and including at least one object class in a first hierarchy level and at least one object class in a second hierarchy level lower than the first hierarchy level, wherein the object class in the higher hierarchy level has a higher level of abstraction than the object class in the lower hierarchy level;
a display control unit configured to display, on a display, at a first magnification rate or a second magnification rate higher than the first magnification rate, the specific image from which the plurality of object classes including the at least one object class in the first hierarchy level and the at least one object class in the second hierarchy level has been detected;
a selection unit configured to select a specific hierarchy level on the basis of a predetermined selection criterion, wherein when the display magnification rate of the specific image is the first magnification rate, the selection unit selects the first hierarchy level as the specific hierarchy level, and when the display magnification rate of the specific image is the second magnification rate higher than the first magnification rate, the selection unit selects the second hierarchy level lower than the first hierarchy level as the specific hierarchy level; and
a notification unit configured to notify a user of one or more of the plurality of object classes, with priority given to an object class belonging to the specific hierarchy level,
wherein in a case where the plurality of object classes organized hierarchically, which has been detected from the specific image, is obtained, the notification unit notifies the user of the object class belonging to the specific hierarchy level selected by the selection unit, with priority given to the object class belonging to the specific hierarchy level.
