A dual-shot image preview method and apparatus is disclosed. An electronic device with dual image sensors provides a preview screen combining in real-time a partial image captured from a first image sensor and a rear image captured from a second image sensor. The partial image is a portion of a front image that includes a desired portion of the user, such as the user's face based on algorithmic detection. The electronic device displays a dual-shot preview screen by overlaying the partial image on the rear image.
