An imaging apparatus including a light emitting device includes a determination unit configured to determine a weighting coefficient of each of a plurality of light metering regions, a calculation unit configured to calculate an amount of main flash light of the light emitting device after performing weighting of the light metering value of each of the plurality of light metering regions according to the weighting coefficient determined by the determination unit, and a selection unit configured to select, from the plurality of light metering regions, a reference region which is used when the weighting coefficient of each of the plurality of light metering regions is determined by the determination unit, and the selection unit selects the reference region in such a manner that a light metering region different from a light metering region whose color information acquired by the color information acquisition unit satisfies a particular condition, is preferentially selected.
