An automatic focusing apparatus includes: plural focus detection units detecting focus states in plural areas independently; a unit measuring detection time of the focus detection units; a unit calculating a maximum focus detection time; a unit calculating defocus amounts based on outputs from the focus detection units; a unit driving a focus lens based on the defocus amounts; and a unit calculating an object predicted position. When the focus detection time exceeds the maximum focus detection time, all detections by the focus detection units are completed, defocus amounts corresponding to the respective plural areas are calculated based on the focus states in the areas detected by the focus detection units, and the focus lens is driven according to an output of the focus detection unit corresponding to a focus target position where a difference between the focus target position and the object predicted position is within an allowable range. |
