Abstract

See full text

An image capture apparatus and control method thereof that improve focus detection accuracy in scenes that have low luminance, contrast, and the like is disclosed. The image capture apparatus has a focus detection mode suited to scenes that have low luminance, contrast, and the like. In this focus detection mode, the focus detection is carried out on the basis of a frequency component extracted from an image signal to which a coefficient for correcting intensity differences between color components is not applied, or to which a coefficient having a lower difference among color components than the computed coefficient has been applied.
