A light amount change period of light from a photometric target is determined, based first and second evaluation values calculated, respectively, based on a predetermined photometric value, and each of photometric values at first and second intervals causing the photometric values to be in the same phase relationship and the opposite phase relationship with the predetermined photometric value, respectively, in a case where the light from the photometric target changes at a predetermined frequency. It is determined whether or not the light from the photometric target changes at a light amount change period corresponding to the predetermined frequency."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image pickup apparatus capable of determining light amount change characteristic, method of determining light amount change characteristic, and storage medium","description":"An image pickup apparatus capable of determining a light amount change characteristic at the time of photographing with high accuracy.
