Based on a ratio of a difference between the luminance value of each region in the image captured with flash light and the luminance value of the corresponding region in the image captured without flash light to the luminance value of the corresponding region in the image captured without flash light, a degree of influence of light representing the influence of light emitted by the light emitting device on the luminance value of each region in the image captured with flash light is calculated. Regions in which the degrees of influence of light are larger than a predetermined threshold are determined as illuminated regions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image processing apparatus and control method therefor","description":"An image captured with flash light and an image captured without flash light are each divided into a plurality of regions, and a luminance value is calculated for each region.
