A digital camera and an auto-focusing method are provided to prevent focusing accuracy from deterioration due to hand trembling or noise. A digital camera includes an estimation value computing unit, a focusing point computing unit(19a), a perspective competition determination unit, and a focusing point selector(19f). The estimation value computing unit computes a first estimation value for focus control of an imaging optical system based on an image signal of a first region of a captured image and computes a second estimation value based on an image signal of a second region smaller than the first region, which is included in the first region. The focusing point computing unit computes a first focusing point of the imaging optical system based on the first estimation value and computes a second focusing point of the imaging optical system based on the second estimation value. The perspective competition determination unit determines whether perspective competition occurs in the first region. The focusing point selector selects one of the first focusing point and the second focusing point based on the determination result of the perspective competition determination unit. The focusing point selector selects the second focusing point when the perspective competition determination unit determines that perspective competition occurs in the first region.
