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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image capture apparatus and control method thereof","description":"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.
