Abstract
A focus detecting device capable of focus detection in a plurality of focus-detecting areas, includes a setter for setting a first group including at least two focus-detecting areas, and a second group including a plurality of focus-detecting areas, which are not included in the first group, and a focus detector means for executing focus detection in the order from the focus-detecting areas included in the first group. The focus detecter ends focus detection without executing focus detection in the focus-detecting areas included in the second group, when the focus-detecting area included in the first group satisfies a predetermined condition.
