Electronic device for analyzing and searching for photo on basis of sound and operation method therefor
Provided are an electronic device for analyzing and searching for a photo on the basis of a sound, and an operation method therefor. The electronic device may: acquire a sound signal by means of a microphone for a preset time before and after a time point at which a photo is captured by using a camera; input a feature vector extracted from the sound signal to an artificial neural network model; acquire at least one type of emotion or taste pertaining to the sound signal by analyzing the feature vector by using the artificial neural network model; and store the at least one type of emotion or taste as metadata for the photo captured by using the camera.
