  • Patent number: 12361639
    Abstract: An electronic device and a control method thereof are provided. The electronic device includes a camera, a camera flash, and at least one processor configured to control the camera to capture a natural light image and a depth image of an object, control the camera and the camera flash to capture an artificial light image of the object, obtain distance information from the depth image to generate a depth mask image, create a cluster mask image from the natural light image, obtain a flash image in which the illuminance of the natural light image has been removed from the illuminance of the artificial light image, obtain an optimization parameter based on the distance information, the depth mask image, the cluster mask image, and the flash image, and obtain three-dimensional topographic information and surface reflection information about the object based on the obtained optimization parameter.
