Abstract
Provided is an image capture apparatus that can perform focus detection based on a focus evaluation value indicating contrast of a subject image included in a focus detection area using an image signal output from an image sensor. In accordance with the extent of a blur amount of the subject image, the image capture apparatus determines how to use a method for performing focus detection through a reciprocating motion of a focus lens and a method for performing focus detection by moving the focus lens in a direction toward which the focus evaluation value increases. Focus detection is performed based on the determination.
