Abstract: A method for generating a depth map includes acquiring at least one image of a scene including a reflective object or a semi-transparent object, acquiring, from the at least one image, a first depth map including a depth value for at least one opaque object which is reflected by the reflective object or viewed through the semi-transparent object, acquiring, from the at least one image, a second depth map including a depth value for the reflective object or the semi-transparent object, and generating a depth map for the scene based on the acquired first depth map and the acquired second depth map, and the generated depth map includes the depth value for the reflective object or the semi-transparent object and the depth value for the at least one opaque object which is reflected by the reflective object or viewed through the semi-transparent object.

Abstract: An electronic device is provided. The electronic device includes a camera and a processor, wherein the processor is configured to obtain a first screen including a plurality of objects through the camera, identify s size of each of the plurality of objects, based on a geometric shape of each of the plurality of objects, identify a relative position of each of the plurality of objects, based on distances between the plurality of objects, obtain a first descriptor of the first screen, based on the size and the relative position of each of the plurality of objects, and display augmented-reality content in a space of the first screen, using the first descriptor.

Abstract: Provided is a method, performed by an electronic device, of reading a barcode, the method including obtaining an image by capturing an image of the barcode, determining a plurality of lines that cover a part of the barcode from the image, obtaining information about a distortion level of the barcode in a region adjacent to each of the plurality of lines, determining at least one line for reading the barcode from among the plurality of lines, based on the obtained information, and reading the barcode based on the determined at least one line.
