The image pickup apparatus calculates reflection luminances of reflected light from an object at pre-emission of a lighting device, detects a face area from an image, divides the face area into blocks, calculates a face reflection luminance from a weighted average of reflection luminances of the blocks and first weights of the blocks, calculates a face ambient light luminance from a weighted average of ambient light luminances of the object of the blocks and second weights of the blocks, and determines an emission amount of the lighting device for main photographing with using the face reflection luminance and the ambient light luminance. A first weight of an abnormal luminance block is reduced than that of a block other than the abnormal luminance block."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image pickup apparatus that controls flash emission amount at photographing and control method therefor","description":"An image pickup apparatus that is capable of reducing influence of abnormal reflection light at pre-emission upon determination of an emission amount for main photographing.
