Abstract
An electronic device is disclosed. The electronic device may comprise: an image sensor for acquiring raw image data corresponding to light of infrared band and visible light band, with respect to an external object; and a processor, wherein the processor is configured to: receive a request for acquiring the raw image data corresponding to the external object; on the basis of the request configured to be performed using a first function of the image sensor, generate an RGB image related to the external object by using first raw image data corresponding to the light of visible light band, obtained through the image sensor, and on the basis of the request configured to be performed using a second function of the image sensor, perform biometric authentication related to the external object by using second raw image data corresponding to the light of infrared band, obtained through the image sensor. In addition, various embodiments recognized through the specification are possible.
