Abstract: A method and device with synthetic image generation is included. A method includes acquiring a first image captured by a first camera and second images captured by a second camera having a narrower field of view (FOV) when the second images are captured thereby than that of the first camera when the first image is captured thereby. The method also includes detecting respective blur statuses of each of the second images, selecting a region of the first image on the basis of the region corresponding to a second image, of the second images, selected based on a determination that the blur status of the second image satisfies a blur condition, and generating a synthetic image by synthesizing together the selected region of the first image and the second images not including the selected second image.

Abstract: A method of recognizing a fingerprint includes generating, by using a fingerprint sensor, an input fingerprint image that is to be used when a fingerprint verification mode is executed; obtaining, from a memory, a registered fingerprint image that is generated from a finger image captured by a camera and stored in the memory prior to the generating the input fingerprint image; determining, from among partial regions of a registered fingerprint image that is obtained, a partial region of the registered fingerprint image, which is superimposed on the input fingerprint image, as a registered superimposed image; converting the registered superimposed image such that a first histogram of the registered superimposed image corresponds to a second histogram of the input fingerprint image; and determining, by comparing the registered superimposed image, which is converted, with the input fingerprint image, whether the input fingerprint image is verified.
