Title: Aperture value calculation for a digital camera capable of displaying and/or recording a movie image

Abstract: There is disclosed a digital camera in which an aperture value is regulated between the open aperture value and a predetermined aperture value during acquisition of a movie image. The predetermined aperture value can be determined based on a range of a luminous flux for use in focal detection. The predetermined aperture value can be set, for example, such that the range between the open aperture value and the predetermined aperture value is suitable for a focal detecting operation.
